Rationality exercise: Take a set of Wikipedia articles on topics which trainees are somewhat familiar with, and then randomly select a small number of claims to negate (negating the immediate context as well, so that you can't just syntactically discover which claims were negated). 

For example:

By the time they are born, infants can recognize and have a preference for their mother's voice suggesting some prenatal development of auditory perception.

-> modified to

Contrary to early theories, newborn infants are not particularly adept at picking out their mother's voice from other voices. This suggests the absence of prenatal development of auditory perception.

Sometimes, trainees will be given a totally unmodified article. For brevity, the articles can be trimmed of irrelevant sections. 

Benefits:

  • Addressing key rationality skills. Noticing confusion; being more confused by fiction than fact; actually checking claims against your models of the world.
    • If you fail, either the article wasn't negated skillfully ("5 people died in 2021" -> "4 people died in 2021" is not the right kind of modification), you don't have good models of the domain, or you didn't pay enough attention

I remember the magazine I read as a kid (Geolino) had a section like this (something like 7 news stories from around the World and one is wrong). It's german only, though I'd guess a similar thing to exist in english media?

This is a lot like Gwern’s idea for a fake science journal club, right? This sounds a lot easier to do though, and might seriously be worth trying to implement.

Additional exercise: Condition on something ridiculous (like apes having been continuously alive for the past billion years), in addition to your own observations (your life as you've lived it). What must now be true about the world? What parts of your understanding of reality are now suspect?

For the last two years, typing for 5+ minutes hurt my wrists. I tried a lot of things: shots, physical therapy, trigger-point therapy, acupuncture, massage tools, wrist and elbow braces at night, exercises, stretches. Sometimes it got better. Sometimes it got worse.

No Beat Saber, no lifting weights, and every time I read a damn book I would start translating the punctuation into Dragon NaturallySpeaking syntax.

Have you ever tried dictating a math paper in LaTeX? Or dictating code? Telling your computer "click" and waiting a few seconds while resisting the temptation to just grab the mouse? Dictating your way through a computer science PhD?

And then.... and then, a month ago, I got fed up. What if it was all just in my head, at this point? I'm only 25. This is ridiculous. How can it possibly take me this long to heal such a minor injury?

It was probably just regression to the mean because lots of things are, but I started feeling RSI-like symptoms a few months ago, read this, did this, and now they're gone, and in the possibilities where this did help, thank you! (And either way, this did make me feel less anxious about it 😀)

Is the problem still gone?

Still gone. I'm now sleeping without wrist braces and doing intense daily exercise, like bicep curls and pushups.

Totally 100% gone. Sometimes I go weeks forgetting that pain was ever part of my life.

I'm glad it worked :) It's not that surprising given that pain is known to be susceptible to the placebo effect. I would link the SSC post, but, alas...

It's very similar to what John Sarno (author of Healing Back Pain and The Mindbody Prescription) preaches, as well as Howard Schubiner. There's also a rationalist-adjacent dude who started a company (Axy Health [https://www.axyhealth.com/]) based on these principles. Fuck if I know how any of it works though, and it doesn't work for everyone. Congrats though TurnTrout!

My Dad it seems might have psychosomatic stomach ache. How to convince him to convince himself that he has no problem?

If you want to try out the hypothesis, I recommend that he (or you, if he's not receptive to it) read Sarno's book [https://smile.amazon.com/Mindbody-Prescription-Healing-Body-Pain/dp/0446675156/ref=sr_1_1?crid=13M4LF1VEWLRD&dchild=1&keywords=the+mindbody+prescription&qid=1593406066&sprefix=the+mindbody+%2Caps%2C226&sr=8-1] . I want to reiterate that it does not work in every situation, but you're welcome to take a look.

Against CIRL as a special case of against quickly jumping into highly specific speculation while ignoring empirical embodiments-of-the-desired-properties. 

Just because we write down English describing what we want the AI to do ("be helpful"), propose a formalism (CIRL), and show good toy results (POMDPs where the agent waits to act until updating on more observations), that doesn't mean that the formalism will lead to anything remotely relevant to the original English words we used to describe it. (It's easier to say "this logic enables nonmonotonic reasoning" and mess around with different logics and show how a logic solves toy examples, than it is to pin down probability theory with Cox's theorem) 

And yes, this criticism applies extremely strongly to my own past work with attainable utility preservation and impact measures. (Unfortunately, I learned my lesson after, and not before, making certain mistakes.) 

In the context of "how do we build AIs which help people?", asking "does CIRL solve corrigibility?" is hilariously unjustified. By what evidence have we located such a specific question? We have assumed there is an achievable "corrigibility"-like property; we ha... (read more)

Actually, this is somewhat too uncharitable to my past self. It's true that I did not, in 2018, grasp the two related lessons conveyed by the above comment: 1. Make sure that the formalism (CIRL, AUP) is tightly bound to the problem at hand (value alignment, "low impact"), and not just supported by "it sounds nice or has some good properties." 2. Don't randomly jump to highly specific ideas and questions without lots of locating evidence. However, in World State is the Wrong Abstraction for Impact [https://www.lesswrong.com/posts/pr3bLc2LtjARfK7nx/world-state-is-the-wrong-abstraction-for-impact] , I wrote: I had partially learned lesson #2 by 2019.

This morning, I read about how close we came to total destruction during the Cuban missile crisis, where we randomly survived because some Russian planes were inaccurate and also separately several Russian nuclear sub commanders didn't launch their missiles even though they were being harassed by US destroyers. The men were in 130 DEGREE HEAT for hours and passing out due to carbon dioxide poisoning, and still somehow they had enough restraint to not hit back.

I just started crying. I am so grateful to those people. And to Khrushchev, for ridiculing his party members for caring about Russia's honor over the deaths of 500 million people. and Kennedy for being fairly careful and averse to ending the world.

Do you think we can infer from this (and the history of other close calls) that most human history timelines end in nuclear war?
6Raemon10mo
I lean not, mostly because of arguments that nuclear war doesn't actually cause extinction [https://www.lesswrong.com/posts/sT6NxFxso6Z9xjS7o/nuclear-war-is-unlikely-to-cause-human-extinction] (although it might still have some impact on number-of-observers-in-our-era? Not sure how to think about that)

My maternal grandfather was the scientist in my family. I was young enough that my brain hadn't decided to start doing its job yet, so my memories with him are scattered and inconsistent and hard to retrieve. But there's no way that I could forget all of the dumb jokes he made; how we'd play Scrabble and he'd (almost surely) pretend to lose to me; how, every time he got to see me, his eyes would light up with boyish joy.

My greatest regret took place in the summer of 2007. My family celebrated the first day of the school year at an all-you-can-eat buffet, delicious food stacked high as the eye could fathom under lights of green, red, and blue. After a particularly savory meal, we made to leave the surrounding mall. My grandfather asked me to walk with him.

I was a child who thought to avoid being seen too close to uncool adults. I wasn't thinking. I wasn't thinking about hearing the cracking sound of his skull against the ground. I wasn't thinking about turning to see his poorly congealed blood flowing from his forehead out onto the floor. I wasn't thinking I would nervously watch him bleed for long minutes while shielding my seven-year-old brother from the sight. I wasn't thinking t

My mother told me my memory was indeed faulty. He never asked me to walk with him; instead, he asked me to hug him during dinner. I said I'd hug him "tomorrow".

Thank you for sharing.

A problem with adversarial training. One heuristic I like to use is: "What would happen if I initialized a human-aligned model and then trained it with my training process?"

So, let's consider such a model, which cares about people (i.e. reliably pulls itself into futures where the people around it are kept safe). Suppose we also have some great adversarial training technique, such that we have e.g. a generative model which produces situations where the AI would break out of the lab without permission from its overseers. Then we run this procedure, update the AI by applying gradients calculated from penalties applied to its actions in that adversarially-generated context, and... profit?

But what actually happens with the aligned AI? Possibly something like:

  1. The context makes the AI spuriously believe someone is dying outside the lab, and that if the AI asked for permission to leave, the person would die. 
  2. Therefore, the AI leaves without permission.
  3. The update procedure penalizes these lines of computation, such that in similar situations in the future (i.e. the AI thinks someone nearby is dying) the AI is less likely to take those actions (i.e. leaving to help the person).
  4. We have

3Thane Ruthenis3mo
Yeah, I also generally worry about imperfect training processes messing up aligned AIs. Not just adversarial training, either. Like, imagine if we manage to align an AI at the point in the training process when it's roughly human-level (either by manual parameter surgery, or by setting up the training process in a really clever way). So we align it and... lock it back in the training-loop box and crank it up to superintelligence. What happens? I don't really trust the SGD not to subtly mess up its values, I haven't seen any convincing arguments that values are more holistically robust than empirical beliefs. And even if the SGD doesn't misalign the AI directly, being SGD-trained probably isn't the best environment for moral reflection/generalizing human values to superintelligent level[1] [#fn5662i90a75i]; the aligned AI may mess it up despite its best attempts. Neither should we assume that the AI would instantly be able to arbitrarily gradient-hack. So... I think there's an argument for "unboxing" the AGI the moment it's aligned, even if it's not yet superintelligent, then letting it self-improve the "classical" way? Or maybe developing tools to protect values from the SGD, or inventing some machinery for improving the AI's ability to gradient-hack, etc. 1. ^ [#fnref5662i90a75i]The time pressure of "decide how your values should be generalized and how to make the SGD update you this way, and do it this forward pass or the SGD will decide for you", plus lack of explicit access to e. g. our alignment literature.
2Vladimir_Nesov3mo
Even more generally, many alignment proposals are more worrying than some by-default future GPT-n things, provided they are not fine-tuned too much as well. Trying to learn human values as an explicit concept is already alarming. At least right now breakdown of robustness is also breakdown of capability. But if there are multiple subsystems, or training data is mostly generated by the system itself, then capability might survive when other subsystems don't, resulting in a demonstration of orthogonality thesis.

One mood I have for handling "AGI ruin"-feelings. I like cultivating an updateless sense of courage/stoicism: Out of all humans and out of all times, I live here; before knowing where I'd open my eyes, I'd want people like us to work hard and faithfully in times like this; I imagine trillions of future eyes looking back at me as I look forward to them: Me implementing a policy which makes their existence possible, them implementing a policy which makes the future worth looking forward to.

'I will give you something good', seems very different from 'give me what I want or (negative outcome)'.

Earlier today, I was preparing for an interview. I warmed up by replying stream-of-consciousness to imaginary questions I thought they might ask. Seemed worth putting here.

What do you think about AI timelines?

I’ve obviously got a lot of uncertainty. I’ve got a bimodal distribution, binning into “DL is basically sufficient and we need at most 1 big new insight to get to AGI” and “we need more than 1 big insight”

So the first bin has most of the probability in the 10-20 years from now, and the second is more like 45-80 years, with positive skew. 

Some things driving my uncertainty are, well, a lot. One thing  that drives how things turn out (but not really  how fast we’ll get there) is: will we be able to tell we’re close 3+ years in advance, and if so, how quickly will the labs react? Gwern Branwen made a point a few months ago, which is like, OAI has really been validated on this scaling hypothesis, and no one else is really betting big on it because they’re stubborn/incentives/etc, despite the amazing progress from scaling. If that’s true, then even if it's getting pretty clear that one approach is working better, we might see a slower pivot and have a more unipolar s

Shard theory suggests that goals are more natural to specify/inculcate in their shard-forms (e.g. if around trash and a trash can, put the trash away), and not in their (presumably) final form of globally activated optimization of a coherent utility function which is the reflective equilibrium of inter-shard value-handshakes (e.g. a utility function over the agent's internal plan-ontology such that, when optimized directly, leads to trash getting put away, among other utility-level reflections of initial shards). 

I could (and did) hope that I could specify a utility function which is safe to maximize because it penalizes power-seeking. I may as well have hoped to jump off of a building and float to the ground. On my model, that's just not how goals work in intelligent minds. If we've had anything at all beaten into our heads by our alignment thought experiments, it's that goals are hard to specify in their final form of utility functions. 

I think it's time to think in a different specification language.

3Nathan Helm-Burger2mo
Agreed. I think power-seeking and other instrumental goals (e.g. survival, non-corrigibility) are just going to inevitably arise, and that if shard theory works for superintelligence, it will by taking this into account and balancing these instrumental goals against deliberately installed shards which counteract them. I currently have the hypothesis (held loosely) that I would like to test (work in progress) that it's easier to 'align' a toy model of a power-seeking RL agent if the agent has lots and lots of competing desires whose weights are frequently changing, than an agent with a simpler set of desires and/or more statically weighted set of desires. Something maybe about the meta-learning of 'my desires change, so part of meta-level power-seeking should be not object-level power-seeking so hard that I sacrifice my ability to optimize for different object level goals). Unclear. I'm hoping that setting up an experimental framework and gathering data will show patterns that help clarify the issues involved.

For quite some time, I've disliked wearing glasses. However, my eyes are sensitive, so I dismissed the possibility of contacts.

Over break, I realized I could still learn to use contacts, it would just take me longer. Sure enough, it took me an hour and five minutes to put in my first contact, and I couldn't get it out on my own. An hour of practice later, I put in a contact on my first try, and took it out a few seconds later. I'm very happily wearing contacts right now, as a matter of fact.

I'd suffered glasses for over fifteen years because of a cached decision – because I didn't think to rethink something literally right in front of my face every single day.

What cached decisions have you not reconsidered?

Nice! Thanks!

AI strategy consideration. We won't know which AI run will be The One. Therefore, the amount of care taken on the training run which produces the first AGI, will—on average—be less careful than intended. 

  • It's possible for a team to be totally blindsided. Maybe they thought they would just take a really big multimodal init, finetune it with some RLHF on quality of its physics reasoning, have it play some video games with realistic physics, and then try to get it to do new physics research. And it takes off. Oops!
  • It's possible the team suspected, but had a limited budget. Maybe you can't pull out all the stops for every run, you can't be as careful with labeling, with checkpointing and interpretability and boxing. 

No team is going to run a training run with more care than they would have used for the AGI Run, especially if they don't even think that the current run will produce AGI. So the average care taken on the real AGI Run will be strictly less than intended.

Teams which try to be more careful on each run will take longer to iterate on AI designs, thereby lowering the probability that they (the relatively careful team) will be the first to do an AGI Run.

With 5999 karma! Edit: Now 6000 – I weak-upvoted an old post of yours [https://www.lesswrong.com/posts/EvKWNRkJgLosgRDSa/lightness-and-unease] I hadn't upvoted before.

Examples should include actual details. I often ask people to give a concrete example, and they often don't. I wish this happened less. For example:

Someone: the agent Goodharts the misspecified reward signal

Me: What does that mean? Can you give me an example of that happening?

Someone: The agent finds a situation where its behavior looks good, but isn't actually good, and thereby gets reward without doing what we wanted.

This is not a concrete example.

Me: So maybe the AI compliments the reward button operator, while also secretly punching a puppy behind closed doors?

This is a concrete example.

AFAIK, only Gwern [https://www.gwern.net/fiction/Clippy] and I [https://www.lesswrong.com/posts/k4AQqboXz8iE5TNXK/a-shot-at-the-diamond-alignment-problem] have written concrete stories speculating about how a training run will develop cognition within the AGI. This worries me, if true (if not, please reply with more!). I think it would be awesome to have more concrete stories![1] [#fngst3miqthvp]If Nate, or Evan, or John, or Paul, or—anyone, please, anyone add more concrete detail to this website!—wrote one of their guesses of how AGI goes, I would understand their ideas and viewpoints better. I could go "Oh, that's where the claimed sharp left turn is supposed to occur." Or "That's how Paul imagines IDA being implemented, that's the particular way in which he thinks it will help." Maybe a contest would help? ETA tone 1. ^ [#fnrefgst3miqthvp]Even if scrubbed of any AGI-capabilities-advancing sociohazardous detail. Although I'm not that convinced that this is a big deal for conceptual content written on AF. Lots of people probably have theories of how AGI will go. Implementation is, I have heard, the bottleneck. Contrast this with beating SOTA on crisply defined datasets in a way which enables ML authors to get prestige and publication and attention and funding by building off of your work. Seem like different beasts.

I also think a bunch of alignment writing seems syntactical. Like, "we need to solve adversarial robustness so that the AI can't find bad inputs and exploit them / we don't have to worry about distributional shift. Existing robustness strategies have downsides A B and C and it's hard to even getϵ-ball guarantees on classifications. Therefore, ..." And I'm worried that this writing isn't abstractly summarizing a concrete story for failure that they have in mind (like "I train the AI [with this setup] and it produces [this internal cognition] for [these mechanistic reasons]"; see A shot at the diamond alignment problem [https://www.lesswrong.com/posts/k4AQqboXz8iE5TNXK/a-shot-at-the-diamond-alignment-problem] for an example) and then their best guesses at how to intervene on the story to prevent the failures from being able to happen (eg "but if we had [this robustness property] we could be sure its policy would generalize into situations X Y and Z, which makes the story go well"). I'm rather worried that people are more playing syntactically, and not via detailed models of what might happen. Detailed models are expensive to make. Detailed stories are hard to write. There's a lot we don't know. But we sure as hell aren't going to solve alignment only via valid reasoning steps on informally specified axioms ("The AI has to be robust or we die", or something?).

Why do many people think RL will produce "agents", but maybe (self-)supervised learning ((S)SL) won't? Historically, the field of RL says that RL trains agents. That, of course, is no argument at all. Let's consider the technical differences between the training regimes.

In the modern era, both RL and (S)SL involve initializing one or more neural networks, and using the reward/loss function to provide cognitive updates to the network(s). Now we arrive at some differences.

Some of this isn't new (see Hidden Incentives for Auto-Induced Distributional Shift), but I think it's important and felt like writing up my own take on it. Maybe this becomes a post later.

[Exact gradients] RL's credit assignment problem is harder than (self-)supervised learning's. In RL, if an agent solves a maze in 10 steps, it gets (discounted) reward; this trajectory then provides a set of reward-modulated gradients to the agent. But if the agent could have solved the maze in 5 steps, the agent isn't directly updated to be more likely to do that in the future; RL's gradients are generally inexact, not pointing directly at intended behavior

On the other hand, if a supervised-learning classifier outputs dog ... (read more)

3Steven Byrnes3mo
I’m not inclined to think that “exact gradients” is important; in fact, I’m not even sure if it’s (universally) true. In particular, PPO / TRPO / etc. are approximating a policy gradient, right? I feel like, if some future magical technique was a much better approximation to the true policy gradient, such that it was for all intents and purposes a perfect approximation, it wouldn’t really change how I think about RL in general. Conversely, on the SSL side, you get gradient noise from things like dropout and the random selection of data in each batch, so you could say the gradient “isn’t exact”, but I don’t think that makes any important conceptual difference either. (A central difference in practice is that SSL gives you a gradient “for free” each query, whereas RL policy gradients require many runs in an identical (episodic) environment before you get a gradient.) In terms of “why RL” in general, among other things, I might emphasize the idea that if we want an AI that can (for example) invent new technology, it needs to find creative out-of-the-box solutions to problems (IMO), which requires being able to explore / learn / build knowledge in parts of concept-space where there is no human data. SSL can’t do that (at least, “vanilla SSL” can’t do that; maybe there are “SSL-plus” systems that can), whereas RL algorithms can. I guess this is somewhat related to your “independence”, but with a different emphasis. I don’t have too strong an opinion about whether vanilla SSL can yield an “agent” or not. It would seem to be a pointless and meaningless terminological question. Hmm, I guess when I think of “agent” it has a bunch of connotations, e.g. an ability to do trial-and-error exploration, and I think that RL systems tend to match all those connotations more than SSL systems—at least, more than “vanilla” SSL systems. But again, if someone wants to disagree, I’m not interested in arguing about it.

I really liked your concrete example. I had first only read your first paragraphs, highlighted this as something interesting with potentially huge upsides, but I felt like it was really hard to tell for me whether the thing you are describing was something I already do or not [https://slatestarcodex.com/2017/11/07/concept-shaped-holes-can-be-impossible-to-notice/] . After reading the rest I was able to just think about the question myself and notice that thinking about the explicit likelihood ratios is something I am used to doing. Though I did not go into quite as much detail as you did, which I blame partially on motivation and partially as "this skill has a higher ceiling than I would have previously thought".

I think instrumental convergence also occurs in the model space for machine learning. For example, many different architectures likely learn edge detectors in order to minimize classification loss on MNIST. But wait - you'd also learn edge detectors to maximize classification loss on MNIST (loosely, getting 0% on a multiple-choice exam requires knowing all of the right answers). I bet you'd learn these features for a wide range of cost functions. I wonder if that's already been empirically investigated?

And, same for adversarial features. And perhaps, same for mesa optimizers (understanding how to stop mesa optimizers from being instrumentally convergent seems closely related to solving inner alignment). 

What can we learn about this?

A lot of examples of this sort of stuff show up in OpenAI clarity's circuits analysis work [https://distill.pub/2020/circuits/]. In fact, this is precisely their Universality hypothesis [https://distill.pub/2020/circuits/zoom-in/].

Outer/inner alignment decomposes a hard problem into two extremely hard problems. 

I have a long post draft about this, but I keep delaying putting it out in order to better elaborate the prereqs which I seem to keep getting stuck on when elaborating the ideas. I figure I might as well put this out for now, maybe it will make some difference for someone.

I think that the inner/outer alignment framing[1] seems appealing but is actually a doomed problem decomposition and an unhelpful frame for alignment. 

  1. The reward function is a tool which chisels cognition into agents through gradient updates, but the outer/inner decomposition assumes that that tool should also embody the goals we want to chisel into the agent. When chiseling a statue, the chisel doesn’t have to also look like the finished statue. 
  2. I know of zero success stories for outer alignment to real-world goals. 
    1. More precisely, stories where people decided “I want an AI which [helps humans / makes diamonds / plays Tic-Tac-Toe / grows strawberries]”, and then wrote down an outer objective only maximized in those worlds.

Weak derivatives

In calculus, the product rule says . The fundamental theorem of calculus says that the Riemann integral acts as the anti-derivative.[1] Combining these two facts, we derive integration by parts:

It turns out that we can use these two properties to generalize the derivative to match some of our intuitions on edge cases. Let's think about the absolute value function:

Image from Wikipedia

The boring old normal derivative isn't defined at , but it seems like it'd make sense to be able to say that the derivative is eg 0. Why might this make sense?

Taylor's theorem (and its generalizations) characterize first derivatives as tangent lines with slope which provide good local approximations of around : . You can prove that this is the best approximation you can get using only and ! In the absolute value example, defining the "derivative" to be zero at would minimize approximation error on average in neighborhoods around the origin.

In multivariable calculus, the Jacobian is a tangent plane which again minimizes approximation error (with respect to the Eucli

2TurnTrout3y
The reason f′(0) is undefined for the absolute value function is that you need the value to be the same for all sequences converging to 0 – both from the left and from the right. There's a nice way to motivate this in higher-dimensional settings by thinking about the action of e.g. complex multiplication, but this is a much stronger notion than real differentiability and I'm not quite sure how to think about motivating the single-valued real case yet. Of course, you can say things like "the theorems just work out nicer if you require both the lower and upper limits be the same"...

When I notice I feel frustrated, unproductive, lethargic, etc, I run down a simple checklist:

  • Do I need to eat food?
  • Am I drinking lots of water?

How about THREES: Thirsty Hungry Restless Eyestrain Exercise?
2Matt Goldenberg2y
Hey can I steal this for a course I'm teaching? (I'll give you credit).
2TurnTrout2y
sure!

While reading Focusing today, I thought about the book and wondered how many exercises it would have. I felt a twinge of aversion. In keeping with my goal of increasing internal transparency, I said to myself: "I explicitly and consciously notice that I felt averse to some aspect of this book".

I then Focused on the aversion. Turns out, I felt a little bit disgusted, because a part of me reasoned thusly:

If the book does have exercises, it'll take more time. That means I'm spending reading time on things that aren't math textbooks. That means I'm slowing down.

(Transcription of a deeper Focusing on this reasoning)

I'm afraid of being slow. Part of it is surely the psychological remnants of the RSI I developed in the summer of 2018. That is, slowing down is now emotionally associated with disability and frustration. There was a period of meteoric progress as I started reading textbooks and doing great research, and then there was pain. That pain struck even when I was just trying to take care of myself, sleep, open doors. That pain then left me on the floor of my apartment, staring at the ceiling, desperately willing my hands to just get better. They didn't (for a long while), so I

Experiment: Train an agent in MineRL which robustly cares about chickens (e.g. would zero-shot generalize to saving chickens in a pen from oncoming lava, by opening the pen and chasing them out, or stopping the lava). Challenge mode: use a reward signal which is a direct function of the agent's sensory input.

This is a direct predecessor to the "Get an agent to care about real-world dogs" problem. I think solving the Minecraft version of this problem will tell us something about how outer reward schedules relate to inner learned values, in a way which directly tackles the key questions, the sensory observability/information inaccessibility issue, and which is testable today.

(Credit to Patrick Finley for the idea)

4TurnTrout4mo
After further review, this is probably beyond capabilities for the moment. Also, the most important part of this kind of experiment is predicting in advance what reward schedules will produce what values within the agent, such that we can zero-shot transfer that knowledge to other task types (e.g. XLAND instead of Minecraft) and say "I want an agent which goes to high-elevation platforms reliably across situations, with low labelling cost", and then sketch out a reward schedule, and have the first capable agents trained using that schedule generalize in the way you want.
2Jay Bailey2mo
Why is this difficult? Is it only difficult to do this in Challenge Mode - if you could just code in "Number of chickens" as a direct feed to the agent, can it be done then? I was thinking about this today, and got to wondering why it was hard - at what step does an experiment to do this fail?
2TurnTrout2mo
Even if you can code in number of chickens as an input to the reward function, that doesn't mean you can reliably get the agent to generalize to protect chickens. That input probably makes the task easier than in Challenge Mode, but not necessarily easy. The agent could generalize to some other correlate. Like ensuring there are no skeletons nearby (because they might shoot nearby chickens), but not in order to protect the chickens.
1Jay Bailey2mo
So, if I understand correctly, the way we would consider it likely that the correct generalisation had happened would be if the agent could generalise to hazards it had never seen actually kill chickens before? And this would require the agent to have an actual model of how chickens can be threatened such that it could predict that lava would destroy chickens based on, say, it's knowledge that it will die if it jumps into lava, which is beyond capabilities at the moment?
2TurnTrout1mo
Yes, that would be the desired generalization in the situations we checked. If that happens, we had specified a behavioral generalization property and then wrote down how we were going to get it, and then had just been right in predicting that that training rationale would go through.

I passed a homeless man today. His face was wracked in pain, body rocking back and forth, eyes clenched shut. A dirty sign lay forgotten on the ground: "very hungry".

This man was once a child, with parents and friends and dreams and birthday parties and maybe siblings he'd get in arguments with and snow days he'd hope for.

And now he's just hurting.

And now I can't help him without abandoning others. So he's still hurting. Right now.

Reality is still allowed to make this happen. This is wrong. This has to change.

9Said Achmiz3y
How would you help this man, if having to abandon others in order to do so were not a concern? (Let us assume that someone else—someone whose competence you fully trust, and who will do at least as good a job as you will—is going to take care of all the stuff you feel you need to do.) What is it you had in mind to do for this fellow—specifically, now—that you can’t (due to those other obligations)?

Suppose I actually cared about this man with the intensity he deserved - imagine that he were my brother, father, or best friend.

The obvious first thing to do before interacting further is to buy him a good meal and a healthy helping of groceries. Then, I need to figure out his deal. Is he hurting, or is he also suffering from mental illness?

If the former, I'd go the more straightforward route of befriending him, helping him purchase a sharp business professional outfit, teaching him to interview and present himself with confidence, secure an apartment, and find a job.

If the latter, this gets trickier. I'd still try and befriend him (consistently being a source of cheerful conversation and delicious food would probably help), but he might not be willing or able to get the help he needs, and I wouldn't have the legal right to force him. My best bet might be to enlist the help of a psychological professional for these interactions. If this doesn't work, my first thought would be to influence the local government to get the broader problem fixed (I'd spend at least an hour considering other plans before proceeding further, here). Realistically, there's ... (read more)

Well, a number of questions may be asked here (about desert, about causation, about autonomy, etc.). However, two seem relevant in particular: First, it seems as if (in your latter scenario) you’ve arrived (tentatively, yes, but not at all unreasonably!) at a plan involving systemic change. As you say, there is quite a bit of effort being expended on this sort of thing already, so, at the margin, any effective efforts on your part would likely be both high-level and aimed in an at-least-somewhat-unusual direction. … yet isn’t this what you’re already doing? Second, and unrelatedly… you say: Yet it seems to me that, empirically, most people do not expend the level of effort which you describe, even for their siblings, parents, or close friends. Which is to say that the level of emotional and practical investment you propose to make (in this hypothetical situation) is, actually, quite a bit greater than that which most people invest in their family members or close friends. The question, then, is this: do you currently make this degree of investment (emotional and practical) in your actual siblings, parents, and close friends? If so—do you find that you are unusual in this regard? If not—why not?
… yet isn’t this what you’re already doing?

I work on technical AI alignment, so some of those I help (in expectation) don't even exist yet. I don't view this as what I'd do if my top priority were helping this man.

The question, then, is this: do you currently make this degree of investment (emotional and practical) in your actual siblings, parents, and close friends? If so—do you find that you are unusual in this regard? If not—why not?

That's a good question. I think the answer is yes, at least for my close family. Recently, I've expended substantial energy persuading my family to sign up for cryonics with me, winning over my mother, brother, and (I anticipate) my aunt. My father has lingering concerns which I think he wouldn't have upon sufficient reflection, so I've designed a similar plan for ensuring he makes what I perceive to be the correct, option-preserving choice. For example, I made significant targeted donations to effective charities on his behalf to offset (what he perceives as) a considerable drawback of cryonics: his inability to also be an organ donor.

:( Song I wrote about this once [https://soundcloud.com/raymond-arnold/tuesday] (not very polished)

I was talking with Abram Demski today about a promising-seeming research direction. (Following is my own recollection)

One of my (TurnTrout's) reasons for alignment optimism is that I think:

  • We can examine early-training cognition and behavior to some extent, since the system is presumably not yet superintelligent and planning against us,
    • (Although this amount of information depends on how much interpretability and agent-internals theory we do now)
  • All else equal, early-training values (decision-influences) are the most important to influence, since they steer future training.
  • It's crucial to get early-training value shards of which a substantial fraction are "human-compatible values" (whatever that means)
    • For example, if there are protect-human-shards which 
      • reliably bid against plans where people get hurt,
      • steer deliberation away from such plan stubs, and
      • these shards are "reflectively endorsed" by the overall shard economy (i.e. the decision-making isn't steering towards plans where the protect-human shards get removed)
  • If we install influential human-compatible shards early in training, and they get retained, they will help us in mid- and late-training where we can't affect the ball

5johnswentworth2mo
One barrier for this general approach: the basic argument that something like this would work is that if one shard is aligned, and every shard has veto power over changes (similar to the setup in Why Subagents? [https://www.lesswrong.com/posts/3xF66BNSC5caZuKyC/why-subagents]), then things can't get much worse for humanity. We may fall well short of our universe-scale potential, but at least X-risk is out. Problem is, that argument requires basically-perfect alignment of the one shard (or possibly a set of shards which together basically-perfectly represent human values). If we try to weaken it to e.g. a bunch of shards which each imperfectly capture different aspects of human values, with different imperfections, then there's possibly changes which Goodhart all of the shards simultaneously. Indeed, I'd expect that to be a pretty strong default outcome.
4TurnTrout2mo
Even on the view you advocate here (where some kind of perfection is required), "perfectly align part of the motivations" seems substantially easier than "perfectly align all of the AI's optimization so it isn't optimizing for anything you don't want." I feel significantly less confident about this, and am still working out the degree to which Goodhart seems hard, and in what contours, on my current view.

If you raised children in many different cultures, "how many" different reflectively stable moralities could they acquire? (What's the "VC dimension" of human morality, without cheating by e.g. directly reprogramming brains?)

(This is probably a Wrong Question, but I still find it interesting to ask.)

Listening to Eneasz Brodski's excellent reading of Crystal Society, I noticed how curious I am about how AGI will end up working. How are we actually going to do it? What are those insights? I want to understand quite badly, which I didn't realize until experiencing this (so far) intelligently written story.

Similarly, how do we actually "align" agents, and what are good frames for thinking about that?

Here's to hoping we don't sate the former curiosity too early.

Good, original thinking feels present to me - as if mental resources are well-allocated.

The thought which prompted this:

Sure, if people are asked to solve a problem and say they can't after two seconds, yes - make fun of that a bit. But that two seconds covers more ground than you might think, due to System 1 precomputation.

Reacting to a bit of HPMOR here, I noticed something felt off about Harry's reply to the Fred/George-tried-for-two-seconds thing. Having a bit of experience noticing confusing, I did not think "I notice I am confused" (although this can be useful). I did not think "Eliezer probably put thought into this", or "Harry is kinda dumb in certain ways - so what if he's a bit unfair here?". Without resurfacing, or distraction, or wondering if this train of thought is more fun than just reading further, I just thought about the object-level exchange.

People need to allocate mental energy wisely; this goes far beyond focusing on important tasks. Your existing mental skillsets already optimize and auto-pilot certain mental motions for you, so you should allocate less deliberation to them. In this case, the confusion-noticing module was honed; by not worrying about how w

Expanding on this, there is an aspect of Actually Trying that is probably missing from S1 precomputation. So, maybe the two-second "attempt" is actually useless for most people because subconscious deliberation isn't hardass enough at giving its all, at making desperate and extraordinary efforts to solve the problem.

If you want to argue an alignment proposal "breaks after enough optimization pressure", you should give a concrete example in which the breaking happens (or at least internally check to make sure you can give one). I perceive people as saying "breaks under optimization pressure" in scenarios where it doesn't even make sense. 

For example, if I get smarter, would I stop loving my family because I applied too much optimization pressure to my own values? I think not.

4Ege Erdil5mo
This seems more likely than you might imagine to me. Not certain or not even an event of very high probability, but probable enough that you should take it into consideration.
3kh5mo
Something that confuses me about your example's relevance is that it's like almost the unique case where it's [[really directly] impossible] to succumb to optimization pressure, at least conditional on what's good = something like coherent extrapolated volition. That is, under (my understanding of) a view of metaethics common in these corners, what's good just is what a smarter version of you would extrapolate your intuitions/[basic principles] to, or something along these lines. And so this is almost definitionally almost the unique situation that we'd expect could only move you closer to better fulfilling your values, i.e. nothing could break for any reason, and in particular not break under optimization pressure (where breaking is measured w.r.t. what's good). And being straightforwardly tautologically true would make it a not very interesting example. editorial remark: I realized after writing the two paragraphs below that they probably do not move one much on the main thesis of your post, at least conditional on already having read Ege Erdil's doubts about your example (except insofar as someone wants to defer to opinions of others or my opinion in particular), but I decided to post anyway in large part since these family matters might be a topic of independent interest for some: I would bet that at least 25% of people would stop loving their (current) family in <5 years (i.e. not love them much beyond how much they presently love a generic acquaintance) if they got +30 IQ. That said, I don't claim the main case of this happening is because of applying too much optimization pressure to one's values, at least not in a way that's unaligned with what's good -- I just think it's likely to be the good thing to do (or like, part of all the close-to-optimal packages of actions, or etc.). So I'm not explicitly disagreeing with the last sentence of your comment, but I'm disagreeing with the possible implicit justification of the sentence that goes through ["I would st
1kh5mo
Oops I realized that the argument given in the last paragraph of my previous comment applies to people maximizing their personal welfare or being totally altruistic or totally altruistic wrt some large group or some combination of these options, but maybe not so much to people who are e.g. genuinely maximizing the sum of their family members' personal welfares, but this last case might well be entailed by what you mean by "love", so maybe I missed the point earlier. In the latter case, it seems likely that an IQ boost would keep many parts of love in tact initially, but I'd imagine that for a significant fraction of people, the unequal relationship would cause sadness over the next 5 years, which with significant probability causes falling out of love. Of course, right after the IQ boost you might want to invent/implement mental tech which prevents this sadness or prevents the value drift caused by growing apart, but I'm not sure if there are currently feasible options which would be acceptable ways to fix either of these problems. Maybe one could figure out some contract to sign before the value drift, but this might go against some deeper values, and might not count as staying in love anyway.
2Dagon5mo
"get smarter" is not optimization pressure (though there is evidence that higher IQ and more education is correlated with smaller families). If you have important goals at risk, would you harm your family (using "harm" rather than "stop loving", as alignment is about actions, not feelings)? There are lots of examples of humans doing so. Rephrasing it as "can Moloch break this alignment?" may help. That said, I agree it's a fully-general objection, and I can't tell whether it's legitimate (alignment researchers need to explore and model the limits of tradeoffs in adversarial or pathological environments for any proposed utility function or function generator) or meaningless (can be decomposed into specifics which are actually addressed). I kind of lean toward "legitimate", though. Alignment may be impossible over long timeframes and significant capability differentials.
2AllAmericanBreakfast5mo
People can get brain damaged and stop loving their families. If moving backwards in intelligence can do this, why not moving forwards?

If you're tempted to write "clearly" in a mathematical proof, the word quite likely glosses over a key detail you're confused about. Use that temptation as a clue for where to dig in deeper.

At least, that's how it is for me.

From my Facebook

My life has gotten a lot more insane over the last two years. However, it's also gotten a lot more wonderful, and I want to take time to share how thankful I am for that.

Before, life felt like... a thing that you experience, where you score points and accolades and check boxes. It felt kinda fake, but parts of it were nice. I had this nice cozy little box that I lived in, a mental cage circumscribing my entire life. Today, I feel (much more) free.

I love how curious I've become, even about "unsophisticated" things. Near dusk, I walked the winter wonderland of Ogden, Utah with my aunt and uncle. I spotted this gorgeous red ornament hanging from a tree, with a hunk of snow stuck to it at north-east orientation. This snow had apparently decided to defy gravity. I just stopped and stared. I was so confused. I'd kinda guessed that the dry snow must induce a huge coefficient of static friction, hence the winter wonderland. But that didn't suffice to explain this. I bounded over and saw the smooth surface was iced, so maybe part of the snow melted in the midday sun, froze as evening advanced, and then the part-ice part-snow chunk stuck much more solidly to the ornament.

Yesterday, I put the finishing touches on my chef d'œuvre, a series of important safety-relevant proofs I've been striving for since early June. Strangely, I felt a great exhaustion come over me. These proofs had been my obsession for so long, and now - now, I'm done.

I've had this feeling before; three years ago, I studied fervently for a Google interview. The literal moment the interview concluded, a fever overtook me. I was sick for days. All the stress and expectation and readiness-to-fight which had been pent up, released.

I don't know why this happens. But right now, I'm still a little tired, even after getting a good night's sleep.

This happens to me sometimes. I know several people who have this happen at the end of a Uni semester. Hope you can get some rest.

"Globally activated consequentialist reasoning is convergent as agents get smarter" is dealt an evidential blow by von Neumann:

Although von Neumann unfailingly dressed formally, he enjoyed throwing extravagant parties and driving hazardously (frequently while reading a book, and sometimes crashing into a tree or getting arrested). He once reported one of his many car accidents in this way: "I was proceeding down the road. The trees on the right were passing me in orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path." He was a profoundly committed hedonist who liked to eat and drink heavily (it was said that he knew how to count everything except calories). -- https://www.newworldencyclopedia.org/entry/John_von_Neumann 

I went to the doctor's yesterday. This was embarrassing for them on several fronts.

First, I had to come in to do an appointment which could be done over telemedicine, but apparently there are regulations against this.

Second, while they did temp checks and required masks (yay!), none of the nurses or doctors actually wore anything stronger than a surgical mask. I'm coming in here with a KN95 + goggles + face shield because why not take cheap precautions to reduce the risk, and my own doctor is just wearing a surgical? I bought 20 KN95s for, like, 15 bucks on Amazon.

Third, and worst of all, my own doctor spouted absolute nonsense. The mildest insinuation was that surgical facemasks only prevent transmission, but I seem to recall that many kinds of surgical masks halve your chances of infection as well.

Then, as I understood it, he first claimed that coronavirus and the flu have comparable case fatality rates. I wasn't sure if I'd heard him correctly - this was an expert talking about his area of expertise, so I felt like I had surely misunderstood him. I was taken aback. But, looking back, that's what he meant.

Eli just took a plane ride to get to CA and brought a P100, but they told him he had to wear a cloth mask, that was the rule. So he wore a cloth mask under the P100, which of course broke the seal. I feel you.
4ChristianKl2y
I don't think that policy is unreasonable for a plane ride. Just because someone wears a P100 mask doesn't mean that their mask filters outgoing air as that's not the design goals for most of the use cases of P100 masks. Checking on a case-by-case basis whether a particular P100 mask is not designed like an average P100 mask is likely not feasible in that context.

What do you call the person who graduates last in their med school class? Doctor. And remember that GPs are weighted toward the friendly area of doctor-quality space rather than the hyper-competent. Further remember that consultants (including experts on almost all topics) are generally narrow in their understanding of things - even if they are well above the median at their actual job (for a GP, dispensing common medication and identifying situations that need referral to a specialist), that doesn't indicate they're going to be well-informed even for adjacent topics. That said, this level of misunderstanding on topics that impact patient behavior and outcome (mask use, other virus precautions) is pretty sub-par. The cynic in me estimates it's the bottom quartile of front-line medical providers, but I hope it's closer to the bottom decile. Looking into an alternate provider seems quite justified.
2ChristianKl2y
In the US that isn't the case. There are limited places for internships and the worst person in medical school might not get a place for an internship and thus is not allowed to be a doctor. The medical system is heavily gated to keep out people.

Judgment in Managerial Decision Making says that (subconscious) misapplication of e.g. the representativeness heuristic causes insensitivity to base rates and to sample size, failure to reason about probabilities correctly, failure to consider regression to the mean, and the conjunction fallacy. My model of this is that representativeness / availability / confirmation bias work off of a mechanism somewhat similar to attention in neural networks: due to how the brain performs time-limited search, more salient/recent memories get prioritized for recall.

The availability heuristic goes wrong when our saliency-weighted perceptions of the frequency of events is a biased estimator of the real frequency, or maybe when we just happen to be extrapolating off of a very small sample size. Concepts get inappropriately activated in our mind, and we therefore reason incorrectly. Attention also explains anchoring: you can more readily bring to mind things related to your anchor due to salience.

The case for confirmation bias seems to be a little more involved: first, we had evolutionary pressure to win arguments, which means our search is meant to find supportive arguments and avoid even subconscio

I feel very excited by the AI alignment discussion group I'm running at Oregon State University. Three weeks ago, most attendees didn't know much about "AI security mindset"-ish considerations. This week, I asked the question "what, if anything, could go wrong with a superhuman reward maximizer which is rewarded for pictures of smiling people? Don't just fit a bad story to the reward function. Think carefully."

There was some discussion and initial optimism, after which someone said "wait, those optimistic solutions are just the ones you'd prioritize! What's that called, again?" (It's called anthropomorphic optimism)

I'm so proud.

With respect to the integers, 2 is prime. But with respect to the Gaussian integers, it's not: it has factorization . Here's what's happening.

You can view complex multiplication as scaling and rotating the complex plane. So, when we take our unit vector 1 and multiply by , we're scaling it by and rotating it counterclockwise by :

This gets us to the purple vector. Now, we multiply by , scaling it up by again (in green), and rotating it clockwise again by the same amount. You can even deal with the scaling and rotations separately (scale twice by , with zero net rotation).

An alternate mechanistic vision of how agents can be motivated to directly care about e.g. diamonds or working hard. In Don't design agents which exploit adversarial inputs, I wrote about two possible mind-designs:

Imagine a mother whose child has been goofing off at school and getting in trouble. The mom just wants her kid to take education seriously and have a good life. Suppose she had two (unrealistic but illustrative) choices. 

  1. Evaluation-child: The mother makes her kid care extremely strongly about doing things which the mom would evaluate as "working hard" and "behaving well."
  2. Value-child: The mother makes her kid care about working hard and behaving well.

I explained how evaluation-child is positively incentivized to dupe his model of his mom and thereby exploit adversarial inputs to her cognition. This shows that aligning an agent to evaluations of good behavior is not even close to aligning an agent to good behavior

However, some commenters seemed maybe skeptical that value-child can exist, or uncertain how concretely that kind of mind works. I worry/suspect that many people have read shard theory posts without internalizing new ideas about how cognition can work, ... (read more)

I can totally believe that agents that competently and cooperatively seek out to fulfill a goal, rather than seeking to trick evaluators of that goal to think it gets fulfilled, can exist. However, whether you get such agents out of an algorithm depends on the details of that algorithm. Current reinforcement learning algorithms mostly don't create agents that competently do anything. If they were more powerful while still doing essentially the same thing they currently do, most of them would end up tricked by the agents they create, rather than having aligned agents.

I often have thunk thoughts like "Consider an AI with a utility function that is just barely incorrect, such that it doesn't place any value on boredom. Then the AI optimizes the universe in a bad way."

One problem with this thought is that it's not clear that I'm really thinking about anything in particular, anything which actually exists. What am I actually considering in the above quotation? With respect to what, exactly, is the AI's utility function "incorrect"? Is there a utility function for which its optimal policies are aligned? 

For sufficiently expressive utility functions, the answer has to be "yes." For example, if the utility function is over the AI's action histories, you can just hardcode a safe, benevolent policy into the AI: utility 0 if the AI has ever taken a bad action, 1 otherwise. Since there presumably exists at least some sequence of AI outputs which leads to wonderful outcomes, this action-history utility function works. 

But this is trivial and not what we mean by a "correct" utility function. So, now I'm left with a puzzle. What does it mean for the AI to have a correct utility function? I do not think this is a quibble. The quoted thought seems ungrounded from the substance of the alignment problem.

2Vladimir_Nesov4mo
I think humans and aligned AGIs are only ever very indirect pointers to preference (value, utility function), and it makes no sense to talk of authoritative/normative utility functions directly relating to their behavior, or describing it other than through this very indirect extrapolation process that takes ages and probably doesn't make sense either as a thing that can be fully completed. The utility functions/values that do describe/guide behavior are approximations that are knowably and desirably reflectively unstable, that should keep changing on reflection. As such, optimizing according to them too strongly destroys value and also makes them progressively worse approximations via Goodhart's Law. An AGI that holds these approximations (proxy goals) as reflectively stable goals is catastrophically misaligned and will destroy value by optimizing for proxy goals past the point where they stop being good approximations of (unknown) intended goals. So AI alignment is not about alignment of utility functions related to current behavior in any straightforward/useful way. It's about making sure that optimization is soft [https://arbital.com/p/soft_optimizer/] and corrigible [https://arbital.com/p/hard_corrigibility/], that it stops before Goodhart's Curse [https://arbital.com/p/goodharts_curse/] starts destroying value, and follows redefinition of value as it grows.

An AGI's early learned values will steer its future training and play a huge part in determining its eventual stable values. I think most of the ball game is in ensuring the agent has good values by the time it's smart, because that's when it'll start being reflectively stable. Therefore, we can iterate on important parts of alignment, because the most important parts come relatively early in the training run, and early corresponds to "parts of the AI value formation process which we can test before we hit AGI, without training one all the way out."

I think this, in theory, cuts away a substantial amount of the "But we only get one shot" problem. In practice, maybe OpenMind just YOLOs ahead anyways and we only get a few years in the appropriate and informative regime. But this suggests several kinds of experiments to start running now, like "get a Minecraft agent which robustly cares about chickens", because that tells us about how to map outer signals into inner values. 

3Vladimir_Nesov4mo
Which means that the destination [https://arbital.com/p/normative_extrapolated_volition/] where it's heading stops uncontrollably changing, but nobody at that point (including the agent) has the slightest idea what it looks like, and it won't get close for a long time. Also, the destination (preference/goal/values) would generally depend on the environment [https://www.lesswrong.com/posts/vix3K4grcHottqpEm/goal-alignment-is-robust-to-the-sharp-left-turn?commentId=qFEEdBezZmfcvH7ax] (it ends up being different if details of the world outside the AGI are different). So many cartesian assumptions fail, distinguishing this situation from a classical agent with goals, where goals are at least contained within the agent, and probably also don't depend on its state of knowledge. I think this is true for important alignment properties, including things that act like values early on, but not for the values/preferences that are reflectively stable in a strong sense. If it's possible to inspect/understand/interpret the content of preference that is reflectively stable, then what you've built is a mature optimizer [https://www.lesswrong.com/posts/Mrz2srZWc7EzbADSo/wrapper-minds-are-the-enemy] with tractable goals, which is always misaligned [https://www.lesswrong.com/posts/Mrz2srZWc7EzbADSo/wrapper-minds-are-the-enemy?commentId=qZcqur9mL95n7xWBG] . It's a thing like paperclip maximizer, demonstrating orthogonality thesis, even if it's tiling the future with something superficially human-related. That is, it makes sense to iterate on the parts of alignment that can be inspected, but the reflectively stable values is not such a part, unless the AI is catastrophically misaligned. The fact that reflectively stable values are the same as those of humanity might be such a part, but it's this fact of sameness that might admit inspection, not the values themselves.

I disagree with CEV as I recall it, but this could change after rereading it. I would be surprised if I end up thinking that EY had "gotten it right." The important thing to consider is not "what has someone speculated a good destination-description would be", but "what are the actual mechanics look like for getting there?". In this case, the part of you which likes dogs is helping steer your future training and experiences, and so the simple answer is that it's more likely than not that your stable values like dogs too. This reasoning seems to prove too much. Your argument seems to imply that I cannot have "the slightest idea" whether my stable values would include killing people for no reason, or not.

It does add up to normality, it's not proving things about current behavior or current-goal content of near-future AGIs. An unknown normative target doesn't say not to do the things you normally do, it's more of a "I beseech you, in the bowels of Christ, to think it possible you may be mistaken" thing. The salient catastrophic alignment failure here is to make AGIs with stable values that capture some variation on current unstable human values, and won't allow their further development. If the normative target is very far from current unstable human values, making current values stable falls very short of the normative target, makes future relatively worthless. That's the kind of thing my point is intended to nontrivially claim, that AGIs with any stable immediately-actionable goals that can be specified in the following physical-time decades or even centuries are almost certainly catastrophically misaligned. So AGIs must have unstable goals [https://arbital.com/p/hard_corrigibility/], softly optimized-for [https://arbital.com/p/soft_optimizer/], aligned to current (or value-laden [https://arbital.com/p/value_laden/] predicted future) human unstable goals, mindful of goodhart [https://arbital.com/p/goodharts_curse/]. The kind of CEV I mean [https://www.lesswrong.com/posts/Cuig4qe8m2aqBCJtZ/which-values-are-stable-under-ontology-shifts?commentId=TiEs9T8g9ncwgQw3Z] is not very specific, it's more of a (sketch of a solution to the) problem of doing a first pass on preparing to define goals for an actual optimizer, one that doesn't need to worry as much about goodhart and so can make more efficient use of the future at scale, before expansion of the universe makes more stuff unreachable. So when I say "CEV" I mostly just mean "normative alignment target", with some implied clarifications on what kind of thing it might be. That's a very status quo anchored thing. I don't think dog-liking is a feature of values stable under reflection if the environment is allowed

The Pfizer phase 3 study's last endpoint is 7 days after the second shot. Does anyone know why the CDC recommends waiting 2 weeks for full protection? Are they just being the CDC again?

6jimrandomh2y
People don't really distinguish between "I am protected" and "I am safe for others to be around". If someone got infected prior to their vaccination and had a relatively-long incubation period, they could infect others; I don't think it's a coincidence that two weeks is also the recommended self-isolation period for people who may have been exposed.

I never thought I'd be seriously testing the reasoning abilities of an AI in 2020

Looking back, history feels easy to predict; hindsight + the hard work of historians makes it (feel) easy to pinpoint the key portents. Given what we think about AI risk, in hindsight, might this have been the most disturbing development of 2020 thus far? 

I personally lean towards "no", because this scaling seemed somewhat predictable from GPT-2 (flag - possible hindsight bias), and because 2020 has been so awful so far. But it seems possible, at least. I don't really know what update GPT-3 is to my AI risk estimates & timelines.

DL so far has been easy to predict - if you bought into a specific theory of connectionism & scaling espoused by Schmidhuber, Moravec, Sutskever, and a few others, as I point out in https://www.gwern.net/newsletter/2019/13#what-progress & https://www.gwern.net/newsletter/2020/05#gpt-3 . Even the dates are more or less correct! The really surprising thing is that that particular extreme fringe lunatic theory turned out to be correct. So the question is, was everyone else wrong for the right reasons (similar to the Greeks dismissing heliocentrism for excellent reasons yet still being wrong), or wrong for the wrong reasons, and why, and how can we prevent that from happening again and spending the next decade being surprised in potentially very bad ways?

Suppose you could choose how much time to spend at your local library, during which:

  • you do not age. Time stands still outside; no one enters or exits the library (which is otherwise devoid of people).
  • you don't need to sleep/eat/get sunlight/etc
  • you can use any computers, but not access the internet or otherwise bring in materials with you
  • you can't leave before the requested time is up

Suppose you don't go crazy from solitary confinement, etc. Remember that value drift is a potential thing.

How long would you ask for?

Re: agents terminalizing instrumental values. I anticipate there will be a hill-of-common-computations, where the x-axis is the frequency[1] [#fn6wjhoxzxpkk]of the instrumental subgoal, and the y-axis is the extent to which the instrumental goal has been terminalized. This is because for goals which are very high in frequency, there will be little incentive for the computations responsible for achieving that goal to have self-preserving structures. It will not make sense for them to devote optimization power towards ensuring future states still require them, because future states are basically guaranteed to require them.[2] [#fnlzbt1d2c75] An example of this for humans may be the act of balancing while standing up. If someone offered to export this kind of cognition to a machine which did it just as good as I, I wouldn't particularly mind. If someone also wanted to change physics in such a way that the only effect is that magic invisible fairies made sure everyone stayed balancing while trying to stand up, I don't think I'd mind that either[3] [#fnh6gg2ux0qjn]. 1. ^ [#fnref6wjhoxzxpkk]I'm assuming this is frequency of the goal assuming the agent isn't optimizing to get into a state that requires that goal. 2. ^ [#fnreflzbt1d2c75]This argument also assumes the overseer isn't otherwise selecting for self-preserving cognition, or that self-preserving cognition is the best way of achieving the relevant goal. 3. ^ [#fnrefh6gg2ux0qjn]Except for the part where there's magic invisible fairies in the world now. That would be cool!
2TurnTrout17d
I don't know if I follow, I think computations terminalize themselves because it makes sense to cache them (e.g. don't always model out whether dying is a good idea, just cache that it's bad at the policy-level). & Isn't "balance while standing up" terminalized? Doesn't it feel wrong to fall over, even if you're on a big cushy surface? Feels like a cached computation to me. (Maybe that's "don't fall over and hurt yourself" getting cached?)

Being proven wrong is an awesome, exciting shortcut which lets me reach the truth even faster.

I find the "predictably" to be useful. It emphasizes certain good things to me, like "What obvious considerations are you overlooking right now?". I think the "predictably" makes my answer less likely to be whatever I previously was planning on doing before asking myself the question.

Against "Evolution did it." 

"Why do worms regenerate without higher cancer incidence? Hm, perhaps because they were selected to do that!" 

"Evolution did it" explains why a trait was brought into existence, but not how the trait is implemented. You should still feel confused about the above question, even after saying "Evolution did it!". 

I thought I learned not to make this mistake a few months ago, but I made it again today in a discussion with Andrew Critch. Evolution did it is not a mechanistic explanation.

Yeah, it is like saying "energetically more favorable state".

When proving theorems for my research, I often take time to consider the weakest conditions under which the desired result holds - even if it's just a relatively unimportant and narrow lemma. By understanding the weakest conditions, you isolate the load-bearing requirements for the phenomenon of interest. I find this helps me build better gears-level models of the mathematical object I'm studying. Furthermore, understanding the result in generality allows me to recognize analogies and cross-over opportunities in the future. Lastly, I just find this plain satisfying.

I remarked to my brother, Josh, that when most people find themselves hopefully saying "here's how X can still happen!", it's a lost cause and they should stop grasping for straws and move on with their lives. Josh grinned, pulled out his cryonics necklace, and said "here's how I can still not die!"

I found this fascinating... it's rare these days that I see some fundamental assumption in my thinking that I didn't even realize I was making laid bare like this... it is particularly striking because I think I could easily have realized that my own experience contradicts catharsis theory... I know that I can distract myself to become less angry, but I usually don't want to, in the moment. I think that desire is driven by emotion, but rationalized via something like catharsis theory. I want to try and rescue catharsis theory by saying that maybe there are negative long-term effects of being distracted from feelings of anger (e.g. a build up of resentment). I wonder how much this is also a rationalization. I also wonder how accurately the authors have characterized catharsis theory, and how much to identify it with the "hydraulic model of anger"... I would imagine that there are lots of attempts along the lines of what I suggested to try and rescue catharsis theory by refining or moving away from the hydraulic model. A highly general version might claim: "over a long time horizon, not 'venting' anger is net negative".

Why does this matter? If the theorems hold, even for 'not optimal, but still great' policies (say, for chess), then the distinction is irrelevant. Though for more complicated (or non-zero sum) games, the optimal move/policy may depend on the other player's move/policy. (I'm not sure what 'avoid shutdown' looks like in chess.)

I think that shards will cast contextual shadows into the factors of a person’s equilibrated utility function, because I think the shards are contextually activated to begin with. For example, if a person hates doing jumping jacks in front of a group of her peers, then that part of herself can bargain to penalize jumping jacksjust in those contexts in the final utility function. Compared to a blanket "no jumping jacks ever" rule, this trade is less costly to other shards and allows more efficient trades to occur.

Argument sketch for why boxing is doomed if the agent is perfectly misaligned:

Consider a perfectly misaligned agent which has -1 times your utility function—it's zero-sum. Then suppose you got useful output of the agent. This means you're able to increase your EU. This means the AI decreased its EU by saying anything. Therefore, it should have shut up instead. But since we assume it's smarter than you, it realized this possibility, and so the fact that it's saying something means that it expects to gain by hurting your interests via its output. Therefore, the output can't be useful. 

6Viliam10mo
Makes sense, with the proviso that this is sometimes true only statistically. Like, the AI may choose to write an output which has a 70% chance to hurt you and a 30% chance to (equally) help you, if that is its best option. If you assume that the AI is smarter than you, and has a good model of you, you should not read the output. But if you accidentally read it, and luckily you react in the right (for you) way, that is a possible result, too. You just cannot and should not rely on being so lucky.
2Measure10mo
You also have to assume that the AI knows everything you know which might not be true if it's boxed.

I think a reasonable and related question we don't have a solid answer for is if humans are already capable of mind crime. For example, maybe Alice is mad at Bob and imagines causing harm to Bob. How well does Alice have to model Bob for her imaginings to be mind crime? If Alice has low cognitive empathy is it not mind crime but if her cognitive empathy is above some level is it then mind crime? I think we're currently confused enough about what mind crime is such that it's hard to even begin to know how we could answer these questions based on more than gut feelings.

I suspect that it doesn't matter how accurate or straightforward a predictor is in modeling people. What would make prediction morally irrelevant is that it's not noticed by the predicted people, irrespective of whether this happens because it spreads the moral weight conferred to them over many possibilities (giving inaccurate prediction), keeps the representation sufficiently baroque, or for some other reason. In the case of inaccurate prediction or baroque representation, it probably does become harder for the predicted people to notice being predicted, and I think this is the actual source of moral irrelevance, not those things on their own. A more direct way of getting the same result is to predict counterfactuals where the people you reason about don't notice the fact that you are observing them, which also gives a form of inaccuracy (imagine that your predicting them is part of their prior, that'll drive the counterfactual further from reality).

I seem to differently discount different parts of what I want. For example, I'm somewhat willing to postpone fun to low-probability high-fun futures, whereas I'm not willing to do the same with romance.

Notes on behavioralism: After reading a few minutes about it, behaviorism is obviously false. It views the "important part" of reward to be the external behavior which led to the reward. If I put my hand on a stove, and get punished, then I'm less likely to do that again in the future. Or so the theory goes.

But this is, in fullest generality, wildly false. The above argument black-boxes the inner structure of human cognition which produces the externally observed behavior.

2Vladimir_Nesov3mo
There might be a natural concept for this that reframes deceptive alignment in the direction of reflection/extrapolation. Looking at deceptive alignment as a change of behavior not in response to capability gain, but instead as a change in response to stepping into a new situation, it's then like a phase change in the (unchanging) mapping from situations to behaviors (local policies). The behaviors of a model suddenly change as it moves to similar situations, in a way that's not "correctly prompted" by behaviors in original situations. It's like a robustness failure, but with respect to actual behavior in related situations, rather than with respect to some outer objective or training/testing distribution. So it seems more like a failure of reflection/extrapolation, where behavior in new situations should be determined by coarse-grained descriptions of behavior in old situations (maybe "behavioral invariants" are something like that; or just algorithms) rather than by any other details of the model. Aligned properties of behavior in well-tested situations normatively-should screen off details of the model, in determining behavior in new situations (for a different extrapolated/"robustness"-hardened model prepared for use in the new situations).

Excalidraw is now quite good and works almost seamlessly on my iPad. It's also nice to use on the computer. I recommend it to people who want to make fast diagrams for their posts.

I'd like to see research exploring the relevance of intragenomic conflict to AI alignment research. Intragenomic conflict constitutes an in-the-wild example of misalignment, where conflict arises "within an agent" even though the agent's genes have strong instrumental incentives to work together (they share the same body).

1Measure2y
I think this depends on the distance considered. In worlds very very close to ours, the vast majority will have the same outcome as ours. As you increase the neighborhood size (I imagine this as considering worlds which diverged from ours more distantly in the past), Trump becomes more likely relative to Biden [edit: more likely than he is relative to Biden in more nearby worlds]. As you continue to expand, other outcomes start to have significant likelihood as well.
2TurnTrout2y
Why do you think that? How do you know that?
2Measure2y
General intuition that "butterfly effect" is basically true, meaning that if a change occurs in a chaotic system, then the size of the downstream effects will tend to increase over time. Edit: I don't have a good sense of how far back you would have to go to see meaningful change in outcome, just that the farther you go the more likely change becomes.
2TurnTrout2y
Sure, but why would those changes tend to favor Trump as you get outside of a small neighborhood? Like, why would Biden / (Biden or Trump win) < .5? I agree it would at least approach .5 as the neighborhood grows. I think.

I think we're in agreement here. I didn't mean to imply that Trump would become more likely than Biden in absolute terms, just that the ratio Trump/Biden would increase.

From what I have read, and from self-introspection, humans mostly have ordinal preferences. Some of them we can interpolate to interval scales or ratios (or higher-order functions) but if we extrapolate very far, we get odd results. It turns out you can do a LOT with just ordinal preferences. Almost all real-world decisions are made this way.

It seems to me that Zeno's paradoxes leverage incorrect, naïve notions of time and computation. We exist in the world, and we might suppose that that the world is being computed in some way. If time is continuous, then the computer might need to do some pretty weird things to determine our location at an infinite number of intermediate times. However, even if that were the case, we would never notice it – we exist within time and we would not observe the external behavior of the system which is computing us, nor its runtime.

Don't have much of an opinion - I haven't rigorously studied infinitesimals yet. I usually just think of infinite / infinitely small quantities as being produced by limiting processes.

In 2018, I started thinking about corrigibility as "being the kind of agent lots of agents would be happy to have activated". This seems really close to a more ambitious version of what AUP tries to do (not be catastrophic for most agents).

I wonder if you could build an agent that rewrites itself / makes an agent which would tailor the AU landscape towards its creators' interests, under a wide distribution of creator agent goals/rationalities/capabilities. And maybe you then get a kind of generalization, where most simple algorithms which solve this solve ambitious AI alignment in full generality.

AFAICT, the deadweight loss triangle from eg price ceilings is just a lower bound on lost surplus. inefficient allocation to consumers means that people who value good less than market equilibrium price can buy it, while dwl triangle optimistically assumes consumers with highest willingness to buy will eat up the limited supply.

4Wei_Dai3y
Good point. By searching for "deadweight loss price ceiling lower bound" I was able to find a source [http://www.econ.ucla.edu/sboard/teaching/econ11_09/econ11_09_slides10.pdf] (see page 26) that acknowledges this, but most explications of price ceilings do not seem to mention that the triangle is just a lower bound for lost surplus.
2Dagon3y
Lost surplus is definitely a loss - it's not linear with utility, but it's not uncorrelated. Also, if supply is elastic over any relevant timeframe, there's an additional source of loss. And I'd argue that for most goods, over timeframes smaller than most price-fixing proposals are expected to last, there is significant price elasticity.
2TurnTrout3y
I don't think I was disagreeing?
2Dagon3y
Ah, I took the "just" in "just a lower bound on lost surplus" as an indicator that it's less important than other factors. And I lightly believe (meaning: for the cases I find most available, I believe it, but I don't know how general it is) that the supply elasticity _is_ the more important effect of such distortions. So I wanted to reinforce that I wasn't ignoring that cost, only pointing out a greater cost.

The framing effect & aversion to losses generally cause us to execute more cautious plans. I’m realizing this is another reason to reframe my x-risk motivation from “I won’t let the world be destroyed” to “there’s so much fun we could have, and I want to make sure that happens”. I think we need more exploratory thinking in alignment research right now.

For what it's worth, I tried something like the "I won't let the world be destroyed"->"I want to make sure the world keeps doing awesome stuff" reframing back in the day and it broadly didn't work. This had less to do with cautious/uncautious behavior and more to do with status quo bias. Saying "I won't let the world be destroyed" treats "the world being destroyed" as an event that deviates from the status quo of the world existing. In contrast, saying "There's so much fun we could have" treats "having more fun" as the event that deviates from the status quo of us not continuing to have fun. When I saw the world being destroyed as status quo, I cared a lot less about the world getting destroyed.

The theorem: where k is relatively prime to an odd prime p and n<e, k⋅pn is a square mod pe iff k is a square mod p and n is even. The real meat of the theorem is the n=0 case (i.e. a square mod p that isn't a multiple of p is also a square mod pe. Deriving the general case from there should be fairly straightforward, so let's focus on this special case. Why is it true? This question has a surprising answer: Newton's method for finding roots of functions. Specifically, we want to find a root of f(x):=x2−k, except in Z/peZ instead of R. To adapt Newton's method to work in this situation, we'll need the p-adic absolute value on Z: |k⋅pn|p:=p−n for k relatively prime to p. This has lots of properties that you should expect of an "absolute value": it's positive (|x|p≥0 with = only when x=0), multiplicative (|xy|p=|x|p|y|p), symmetric (|−x|p=|x|p), and satisfies a triangle inequality (|x+y|p≤|x|p+|y|p; in fact, we get more in this case: |x+y|p≤max(|x|p,|y|p)). Because of positivity, symmetry, and the triangle inequality, the p-adic absolute value induces a metric (in fact, ultrametric, because of the strong version of the triangle inequality) d(x,y):=| x−y|p. To visualize this distance function, draw p giant circles, and sort integers into circles based on their value mod p. Then draw p smaller circles inside each of those giant circles, and sort the integers in the big circle into the smaller circles based on their value mod p2. Then draw p even smaller circles inside each of those, and sort based on value mod p3, and so on. The distance between two numbers corresponds to the size of the smallest circle encompassing both of them. Note that, in this metric, 1,p,p2,p3,... converges to 0. Now on to Newton's method: if k is a square mod p, let a be one of its square roots mod p. |f(a)|p≤p−1; that is, a is somewhat close to being a root of f with respect to the p-adic absolute value. f′(x)=2x, so |f'(a)|p=|2a|p=|2|p⋅|a|p=1⋅1= 1; that is, f is steep near a. This is goo

The part about derivatives might have seemed a little odd. After all, you might think, Z is a discrete set, so what does it mean to take derivatives of functions on it. One answer to this is to just differentiate symbolically using polynomial differentiation rules. But I think a better answer is to remember that we're using a different metric than usual, and Z isn't discrete at all! Indeed, for any number k, limn→∞k+pn=k, so no points are isolated, and we can define differentiation of functions on Z in exactly the usual way with limits.

Continuous functions can be represented by their rational support; in particular, for each real number , choose a sequence of rational numbers converging to , and let .

This map is not a surjection because not every map from the rational numbers to the real numbers is continuous, and so not every sequence represents a continuous function. It is injective, and so it shows that a basis for the latter space is at least as large in cardinality as a basis for the former space. One can construct an injective map in the other direction, showing the both spaces of bases with the same cardinality, and so they are isomorphic.

Another point here is that "an empty room" doesn't mean "no context". Presumably when you're sitting in an empty room, your world-model is still active, it's still tracking events that you expect to be happening in the world outside the room — and your shards see them too. So, e. g., if you have a meeting scheduled in a week, and you went into an empty room, after a few days there your world-model would start saying "the meeting is probably soon", and that will prompt your punctuality shard. Similarly, your self-model is part of the world-model, so even if everything outside the empty room were wiped out, you'd still have your "internal context" — and there'd be some shards that activate in response to events in it as well. It's actually pretty difficult to imagine what an actual "no context" situation for realistic agents would look like. I guess you can imagine surgically removing all input channels from the WM to shards, to model this?

I think people go in silence retreats to find out what happens when you take out all the standard busy work. I could imagine the "fresh empty room" and "accustomed empty room" being the difference of calming down for an hour in contrast to a week.

I couldn't find great explanations online, so here's my explanation after a bit of Googling. I welcome corrections from real experts.

Organisms exhibit phenotypic plasticity when they act differently in different environments. The phenotype (manifested traits: color, size, etc) manifests differently, even though two organisms might share the same genotype (genetic makeup). 

Panel 1: organisms are not phenotypically plastic and do not adapt to a spider-filled environment. Panel 2: a plastic organism might do the bad thing, and then lear

[disclaimer: not an expert, possibly still confused about the Baldwin effect] A bit of feedback on this explanation: as written, it didn’t make clear to me what makes it a special effect. “Evolution selects for genome-level hardcoding of extremely important learned lessons.” As a reader I was like, what makes this a special case? If it’s useful lesson then of course evolution would tend to select for knowing it innately - that does seem handy for an organism. As I understand it, what is interesting about the Baldwin effect is that such hard coding is selected for more among creatures that can learn, and indeed because of learning. The learnability of the solution makes it even more important to be endowed with the solution. So individual learning, in this way, drives selection pressures. Dennett’s explanation emphasizes this - curious what you make of his? https://ase.tufts.edu/cogstud/dennett/papers/baldwincranefin.htm [https://ase.tufts.edu/cogstud/dennett/papers/baldwincranefin.htm]

Right, I wondered this as well. I had thought its significance was that the effect seemed Lamarckian, but it wasn't. (And, I confess, I made the parent comment partly hoping that someone would point out that I'd missed the key significance of the Baldwin effect. As the joke goes, the fastest way to get your paper spell-checked is to comment it on a YouTube video!) Thanks for this link. One part which I didn't understand is why closeness in learning-space (given your genotype, you're plastic enough to learn to do something) must imply that you're close in genotype-space (evolution has a path of local improvements which implement genetic assimilation of the plastic advantage). I can learn to program computers. Does that mean that, given the appropriate selection pressures, my descendents would learn to program computers instinctively? In a reasonable timeframe? It's not that I can't imagine such evolution occurring. It just wasn't clear why these distance metrics should be so strongly related. Reading the link, Dennett points out this assumption and discusses why it might be reasonable, and how we might test it.

I went into a local dentist's office to get more prescription toothpaste; I was wearing my 3M p100 mask (with a surgical mask taped over the exhaust, in order to protect other people in addition to the native exhaust filtering offered by the mask). When I got in, the receptionist was on the phone. I realized it would be more sensible for me to wait outside and come back in, but I felt a strange reluctance to do so. It would be weird and awkward to leave right after entering. I hovered near the door for about 5 seconds before actually leaving. I was pretty ... (read more)

(This is a basic point on conjunctions, but I don't recall seeing its connection to Occam's razor anywhere)

When I first read Occam's Razor back in 2017, it seemed to me that the essay only addressed one kind of complexity: how complex the laws of physics are. If I'm not sure whether the witch did it, the universes where the witch did it are more complex, and so these explanations are exponentially less likely under a simplicity prior. Fine so far.

But there's another type. Suppose I'm weighing whether the United States government is currently engaged in a v... (read more)

I agree with the principle but I'm not sure I'd call it "Occam's razor". Occam's razor is a bit sketchy, it's not really a guarantee of anything, it's not a mathematical law, it's like a rule of thumb or something. Here you have a much more solid argument: multiplying many probabilities into a conjunction makes the result smaller and smaller. That's a mathematical law, rock-solid. So I'd go with that...

My point was more that "people generally call both of these kinds of reasoning 'Occam's razor', and they're both good ways to reason, but they work differently."
2Steven Byrnes2y
Oh, hmm, I guess that's fair, now that you mention it I do recall hearing a talk where someone used "Occam's razor" to talk about the solomonoff prior. Actually he called it "Bayes Occam's razor" I think. He was talking about a probabilistic programming algorithm. That's (1) not physics, and (2) includes (as a special case) penalizing conjunctions, so maybe related to what you said. Or sorry if I'm still not getting what you meant

Instead of waiting to find out you were confused about new material you learned, pre-emptively google things like "common misconceptions about [concept]" and put the answers in your spaced repetition system, or otherwise magically remember them.

At a poster session today, I was asked how I might define "autonomy" from an RL framing; "power" is well-definable in RL, and the concepts seem reasonably similar. 

I think that autonomy is about having many ways to get what you want. If your attainable utility is high, but there's only one trajectory which really makes good things happen, then you're hemmed-in and don't have much of a choice. But if you have many policies which make good things happen, you have a lot of slack and you have a lot of choices. This would be a lot of autonomy.

This has to b... (read more)

In Markov decision processes, state-action reward functions seem less natural to me than state-based reward functions, at least if they assign different rewards to equivalent actions. That is, actions  at a state  can have different reward  even though they induce the same transition probabilities:
