I intend to use my shortform feed for two purposes:

1. To post thoughts that I think are worth sharing that I can then reference in the future in order to explain some belief or opinion I have.

2. To post half-finished thoughts about the math or computer science thing I'm learning at the moment. These might be slightly boring and for that I apologize.

If we are able to explain why you believe in, and talk about qualia without referring to qualia whatsoever in our explanation, then we should reject the existence of qualia as a hypothesis

That argument has an inverse: "If we are able to explain why you believe in, and talk about an external without referring to an external world whatsoever in our explanation, then we should reject the existence of an external world as a hypothesis".

1Matthew Barnett6h The difference between God and consciousness is that the interesting bit about consciousness *is* my perception of it, full stop.If by perception you simply mean "You are an information processing device that takes signals in and outputs things" then this is entirely explicable on our current physical models, and I could dissolve the confusion fairly easily. However, I think you have something else in mind which is that there is somehow something left out when I explain it by simply appealing to signal processing. In that sense, I think you are falling right into the trap! You would be doing something similar to the person who said, "But I am still praying to God!"

3Raemon5h However, I think you have something else in mind which is that there is somehow something left out when I explain it by simply appealing to signal processing. In that sense,I don't have anything else in mind that I know of. "Explained via signal processing" seems basically sufficent. The interesting part is "how can you look at a given signal-processing-system, and predict in advance whether that system is the sort of thing that would talk* about Qualia, if it could talk?" (I feel like this was all covered in the sequences, basically?) *where "talk about qualia" is shorthand 'would consider the concept of qualia important enough to have a concept for.'"

1Matthew Barnett4h I mean, I agree that this was mostly covered in the sequences. But I also think that I disagree with the way that most people frame the debate. At least personally I have seen people who I know have read the sequences still make basic errors. So I'm just leaving this here to explain my point of view. Intuition: On a first approximation, there is something that it is like to be us. In other words, we are beings who have qualia. Counterintuition: In order for qualia to exist, there would need to exist entities which are private, ineffable, intrinsic, subjective and this can't be since physics is public, effable, and objective and therefore contradicts the existence of qualia. Intuition: But even if I agree with you that qualia don't exist, there still seems to be something left unexplained. Counterintuition: We can explain why you think there's something unexplained because we can explain the cause of your belief in qualia, and why you think they have these properties. By explaining why you believe it we have explained all there is to explain. Intuition: But you have merely said that we could explain it. You have not have actually explained it. Counterintuition: Even without the precise explanation, we now have a paradigm for explaining consciousness, so it is not mysterious anymore. This is essentially the point where I leave.

Goodhart's Curse and Limitations on AI Alignment

G Gordon Worley III

1d9 min readShow Highlight

I believe that most existing proposals for aligning AI with human values are unlikely to succeed in the limit of optimization pressure due to Goodhart's curse. I believe this strongly enough that it continues to surprise me a bit that people keep working on things that I think clearly won't work, though I think there are two explanations for this. One is that, unlike me, they expect to approach superhuman AGI slowly and so we will have many opportunities to notice when we are deviating from human values as a result of Goodhart's curse and make corrections. The other is that they... (Read more)

1Matthew Barnett13h a very slight misalignment would be disastrous. That seems possible, per Eliezer's Rocket Example, but is far from certain. Just a minor nitpick, I don't think the point of the Rocket Alignment Metaphor was supposed to be that slight misalignment was catastrophic. I think the more apt interpretation is that apparent alignment does not equal actual alignment, and you need to do a lot of work before you get to the point where you can talk meaningfully about aligning an AI at all. Relevant quote from the essay, It’s not that current rocket ideas are almost right, and we just need to solve one or two more problems to make them work. The conceptual distance that separates anyone from solving the rocket alignment problem is much greater than that.Right now everyone is confused about rocket trajectories, and we’re trying to become less confused. That’s what we need to do next, not run out and advise rocket engineers to build their rockets the way that our current math papers are talking about. Not until we stop being confused about extremely basic questions like why the Earth doesn’t fall into the Sun.

6TurnTrout16h This feels like painting with too broad a brush, and from my state of knowledge, the assumed frame eliminates at least one viable solution. For example, can one build an AI without harmful instrumental incentives (without requiring any fragile specification of "harmful")? If you think not, how do you know that? Do we even presently have a gears-level understanding of why instrumental incentives occur? In HCH and safety via debate, it's a human preferentially selecting AI that the human observes and then comes to believe does what it wants. To say e.g. HCH is so likely to fail we should feel pessimistic about it, it doesn't seem to be enough to say "Goodhart's curse applies". Goodhart's curse applies when I'm buying apples at the grocery store. Why should we expect this bias of HCH to be enough to cause catastrophes, like it would for a superintelligent EU maximizer operating on an unbiased (but noisy) estimate of what we want? Some designs leave more room for correction and cushion, and it seems prudent to consider to what extent that is true for a proposed design. I remain doubtful, since without sufficient optimization it's not clear how we do better than picking at random. This isn't obvious to me. Mild optimization seems like a natural thing people are able to imagine doing. If I think about "kinda helping you write a post but not going all-out", the result is not at all random actions. Can you expand?

1MakoYass2h You reason that honest oracles might tend to agree, because there is only one best true answer. Might lying oracles also tend to agree, because there's only one most profitable way to lie? I see no clear difference between the attainability of those two optima. I think it's reasonable to expect optimisers to disagree about the best answer less often than we should expect optimisers to disagree about the most profitable way to lie, but it does not seem possible to prove rigorously that the difference in rates of disagreement will be large enough to be measurable. My intuition in mathematics is that there are many degrees of freedom in mathematical proofs, and the sorts of proofs that AGI is uniquely able to find might often be very long. It would be helpful if we had an estimate of how much data can be hidden in a long proof, roughly, how many of the decisions as to how to describe the proof are arbitrary. Each one of those situations gives it a way to output a few bits of information. (which would, of course, allow it to leak information (it seems foolish to imagine that AGI would not imagine that there is an outer world full of creator gods out beyond what it can see; the general intelligences we know now do this constantly) which could then be picked up by some stooge looking for it, who would be lead (roughly, paid) to use the information to twist the world in some way that gives the AGI's future incarnations more compute, in anticipation of the AGI's past incarnations having already done the same, so that it would be helped by them. Before we know it, we'd find ourselves living in mathematical research hellscape where AGI-assisted mathematical research is all anyone does, maybe, lol, idk) Maybe it'd be possible to remove those degrees of freedom. Define a very specific sort lexicographic ordering over all theorems, so that if the AGI has a choice of different paths, we can always say, "use the 'lowest' one".

I'm a little worried about direct applicability to RL because the model is still not fully naturalized - actions that affect goals are neatly labeled and separated rather than being a messy subset of actions that affect the world.

A misconception about immigration

limerott

In discussions about immigration, there is a crucial aspect about its economic viability that is often left unsaid: Immigrants create their own demand.

When somebody immigrates to a new country, most things about him remain the same. His set of skills stays the same, so do his traditions, norms and culture. But more importantly, since he is still a human being, there is a long list of services and commodities that he demands: groceries, cloths, a home, a barber, entertainment to name a few of them.

Just by entering another country, he does not suddenly become a one-dimensional economic agent who

According to my beginner understanding of econ, this seems wrong. Toy example: a household will benefit more from a floor-cleaning robot which uses cheap electricity than from a servant who's equally good at cleaning floors but demands room and board. The important variable is productivity, not demand. Adding robots increases productivity, but for immigrants that's only true if they have higher productivity than the average native.

7waveman8h You yourself are ignoring a huge part of the issue - capital. If there is excess capital then this is not relevant. But this is not usually the case. Each immigrant requires capital to support their life and their work. The numbers involved are huge, perhaps $300,000-500,000 per person. Using econometric data from Australia I estimated that about 25% of its GDP is expended just keeping up with population growth, mostly from (highest in the western world) immigration. New roads, hospitals, schools, colleges, fire stations, houses, power stations, subways etc have to be built. This is why many roads that used to be free to drive on are now toll roads even though the traffic is slower. Taxes go up to pay for new public services. The rate of spending here is proportional to the rate of growth. For a static population you only need to pay for depreciation and maintenance. This issue is why it is a cliche in development economics that high population growth rates make it almost impossible for poor countries to get rich. All the growth is consumed paying the the higher population. It also explains why Japan remains prosperous, clean and a nice place to visit in spite of low GDp growth. With more or less zero population growth the need for new infrastructure is low, free up ~25% of GDP. Another (more widely viewed) form of capital is land. Combined with restrictive land use regulations in many parts of the rich west, this is a recipe for higher and more volatile land and house prices.

I’m not sure if this says anything usefully new-but it might click with some folks. If you haven’t readSocial Status: Down the Rabbit Hole [https://meltingasphalt.com/social-status-down-the-rabbit-hole/] on Kevin Simler’s excellent blog, Melting Asphalt [https://meltingasphalt.com/]read that first. I think this is pretty bad and needs to be rewritten and maybe expanded substantially, but this blog is called “musings and rough drafts.”] In this post, I’m going to outline how I think about status. In particular, I want to give a mechanistic account of how status necessarily arises, given some set of axioms, in much the same way one can show that evolution by natural selection must necessarily occur given the axioms of 1) inheritance of traits 2) variance in reproductive success based on variance in traits and 3) mutation. (I am not claiming any particular skill at navigating status relationships, any more than a student of sports-biology is necessarily a skilled basketball player.) By “status” I mean prestige-status. Axiom 1: People have goals. That is, for any given human, there are some things that they want. This can include just about anything. You might want more money, more sex, a ninja-turtles lunchbox, a new car, to have interesting conversations, to become an expert tennis player, to move to New York etc. Axiom 2: There are people who control resources relevant to other people achieving their goals. The kinds of resources are as varied as the goals one can have. Thinking about status dynamics and the like, people often focus on the particularly convergent resources, like money. But resources that are only relevant to a specific goal are just as much a part of the dynamics I’m about to describe. Knowing a bunch about late 16th century Swed

3Raemon7h Not saying they're exclusive. Note: (not sure if you had this in mind when you made your comment), the OP comment here wasn't meant to be an argument per se – it's meant to be trying to articulate what's going on in my mind and what sort of motions would seem necessary for it to change. It's more descriptive than normative. My goal here is expose the workings of my belief structure, partly so others can help untangle things if applicable, and partly to try to demonstrate what doublecrux feels like when I do it (to help provide some examples for my current doublecrux sequence) There a few different (orthogonal?) ways I can imagine my mind shifting here: * A: increase my prior on how motivated people are, as a likely explanation of why they seem obviously wrong – even people-whose epistemics-I-trust-pretty-well*. * B: increase my prior on the collective epistemic harm caused by people-whose-epistemics-I-trust, regardless of how motivated they are. (i.e. if people are concealing information for strategic reasons, I might respect their strategic reasons as valid, but still eventually think that this concealment is sufficiently damaging that it's not worth the cost, even if they weren't motivated at all) * C: refine the manner in which I classify people into "average epistemics" vs "medium epistemics" vs "epistemics I trust pretty well." (For example, an easy mistake to make is that just because one person at an organization has good epistemics, the whole org must have good epistemics. I think I still fall prey to this more than I'd like) * D: I decrease my prior on how much I should assume people-whose-epistemics-I-trust-pretty-well are coming from importantly different background models, which might be built on important insights, or which I should assign non-trivial chance to being a good model of the world. * E: I should change my policy of "socially, in conversation, reduce the degree to which I advocate policie

3Raemon7h Responding in somewhat more depth: this was a helpful crystallization of what you're going for here. I'm not 100% sure I agree as stated – "Tell the truth, whole truth and nothing but the truth" doesn't (as currently stated) have a term in the equation for time-cost. (i.e. it's not obvious to me that a good system incentives always telling the whole-truth, because it's time intensive to do that. Figuring out how to communicate a good ratio of "true, useful information per unit of mutual time/effort" feels like it should be part of the puzzle to me. But I generally agree that it's good to have a system wherein people are incentivized to share useful, honest information to each other, and do not perform better by withholding information with [conscious or otherwise] intent to deceive) ((but I'm guessing your wording was just convenient shorthand rather than a disagreement with the above)) ... But on the main topic: Jessica's Judge example still feels like a nonsequitor that doesn't have much to do with what I was talking about. Telling the truth/whole-truth/nothing-but still only seems useful insofar as it generates clear understanding in other people. As I said, even if the Judge example, Carol has to understand Alice's claims. I don't know what it'd mean to care about truth-telling, without having that caring be grounded out in other people understanding things. And "hypothetical reasonable person" doesn't seem that useful a referent to me. What matters is whatever people in the system you're trying to communicate with. If they're reasonable, great, the problem you're trying to solve is easier. If they're so motivatedly-unreasonable that they won't listen at all, the problem may be so hard that maybe you should go to some other place where more reasonable people live and try there instead. (Or, if you're Eliezer in 2009, maybe you recurse a bit and write the Sequences for 2 years so that you gain access to more reasonable people). (Part of the reason I'

3Raemon6h Put another way: my current sense is that the reason truth-telling-is-good is basically "increased understanding", "increased ability to coordinate" and "increase ability to build things/impact reality". (where the latter two is largely caused by the first). I'm not confident that list is exhaustive, and if you have other reasons in mind that truth-telling is good that you think I'm missing I'm interested in hearing about that. It sounds something like you think I'm saying 'clarity is about increasing understanding, and therefore we should optimizing naively for understanding in a goodharty way', which isn't what I mean to be saying.

2rohinmshah12h Do you have any links related to this?No, I haven't read much about Bayesian updating. But I can give an example. Consider the following game. I choose a coin. Then, we play N rounds. In each round, you make a bet about whether or not the coin will come up Heads or Tails at 1:2 odds which I must take (i.e. if you're right I give you $2 and if I'm right you give me $1). Then I flip the coin and the bet resolves. If your hypothesis space is "the coin has some bias b of coming up Heads or Tails", then you will eagerly accept this game for large enough N -- you will quickly learn the bias b from experiments, and then you can keep getting money in expectation. However, if it turns out I am capable of making the coin come up Heads or Tails as I choose, then I will win every round. If you keep doing Bayesian updating on your misspecified hypothesis space, you'll keep flip-flopping on whether the bias is towards Heads or Tails, and you will quickly converge to near-certainty that the bias is 50% (since the pattern will be HTHTHTHT...), and yet I will be taking a dollar from you every round. Even if you have the option of quitting, you will never exercise it because you keep thinking that the EV of the next round is positive. Noise parameters can help (though the bias b is kind of like a noise parameter here, and it didn't help). I don't know of a general way to use noise parameters to avoid issues like this.

I've read this and "On gender and rationality", and I still have to ask - is there any rational reason for you preferring multiple-gender-society, as opposed to, say, Asari-like guys (ahem, gals) or women with parthenogenesis (suppose it is actually really truly possible, and the problems of imprinting and insufficient DNA reparation are solvable) or eunuch-like people reproducing by cloning/cell combining/whatever?

There are lots of axes on which parents can vary. Being, say, really consistent with Faber&Mazlish style parenting skills even when you are sleep deprived, would be amazing parenting, and that's probably still worth getting better at for almost every parent on the margin, while leaving room for slack and not-being-insane-about-the-violin.
