This could have been a post so more people could link it (many don't reflexively notice that you can easily get a link to a Lesswrong quicktake or Twitter or facebook post by mousing over the date between the upvote count and the poster, which also works for tab and hotkey navigation for people like me who avoid using the mouse/touchpad whenever possible).

It not being linked on Twitter and Facebook seems more like a feature than a bug, given that when I asked Gwern why a page like this doesn't already exist, he wrote me he doesn't want people to mock it.

Things I learned that surprised me from a deep dive into how the medication I've been taking for years (Vyvanse) actually gets metabolized:

It says in the instructions that it works for 13 hours, and my psychiatrist informed me that it has a slow onset of about an hour. What that actually means is that after ~1h you reach 1/2 the peak concentration and after 13 hours you are at 1/2 the peak concentration again, because the half-life is 12h (and someone decided at some point 1/2 is where we decide the exponential starts and ends?). Importantly, this means 1/4 of the medication is still present the next day!

Here is some real data, which fit the simple exponential decay rather well (It's from children though, which metabolize dextroamphetamine faster, which is why the half-life is only ~10h)

If you eat ~1-3 grams of baking soda, you can make the amount of medication you lose through urine (usually ~50%) go to 0^[1] (don't do this! Your body probably keeps its urine pH at the level it does for a reason! You could get kidney stones).
I thought the opposite effect (acidic urine gets rid of the medication quickly) explained why my ADHD psychologist had told me that the medicatio

This seems like it will be useful for me in the future. I’ve been wondering for a while how the long half life of ADHD meds impact sleep. Any data on that?

4Morpheus1y

There is probably a lot of variation between people regarding that. In my family meds across the board improved people's sleep (by making people less sleepy during the day, so more active and less naps). When I reduced my medication from 70mg to 50mg for a month to test whether I still needed the full dose, the thing that was annoying the most was my sleep (waking up at night and not falling asleep again increased. Falling asleep initially was maybe slightly easier). Taking it too late in the afternoon is really bad for my sleep, though.

2keltan1y

That matches with what my psychiatrist told me. I find it surprising how large the variation between individuals can be with these meds. I have met people who can drink an espresso before bed and it actually helps their sleep. But I find those people to be rare. I see much more variance in amphetamines. My mental data set isn’t large enough to make any sold predictions. But I am unable to point to a clear “most people's sleep is (X)ed by amphetamines”.

1Morpheus1y

One confounder: depression/mania. Recently (the last ~two weeks) I have been having bad sleep (waking up 3-7 am and not feeling sleepy anymore (usually I sleep from midnight to 9). My current best guess is that the problem is that my life has been going too well recently, leading to a self-sustaining equilibrium where I have little sleep and mania. Reduced my medication today (~55mg instead of 70mg) which seems to have helped with the mania. I had another day with slight mania 1 month ago when sleeping little in order to travel to a conference, so in the future I'll probably reduce my medication dose on such days. Took a friend describing his symptoms on too much medication for me to realize what is going on.

I am in the waiting room at the doctor and the ~1 year old child next to me is scrolling through YouTube shorts on his mother's phone with the mom watching along. Incredibly incoherent AI slop. Not an expert at early development, but this seems very suboptimal. I know that scrolling is not good for my reward system, but a 1-year old? At least put some random video on instead of letting the child scroll? If I was in charge at Google and was living by "don't be evil", I would maybe make a classifier to identify children scrolling like this and giving a reminder once in a while to suggest some alternative activities to the parent?

[-]TsviBT4mo2010

Something like this has been happening for at least a decade. See "Something is wrong on the internet ". There should be enough data at this point for someone to do good studies on whether this behavior has noticeable effects later on.

Adding to that, there's the brainrot (aka sludge) genre of TikTok and YT Shorts content, which is really weird and often AI-generated, and often has Roblox or Subway Surfer content in the background and stuff like that.

If legibility of expertise is a bottleneck to progress and adequacy of civilization, it seems like creating better benchmarks for knowledge and expertise for humans might be a valuable public good. While that seems difficult for aesthetics, it seems easier for engineering? I'd rather listen to a physics PhD, who gets Thinking Physics questions right (with good calibration), years into their professional career, than one who doesn't.

One way to do that is to force experts to make forecasts, but this takes a lot of time to hash out and even more time to resolve.

One idea I just had related to this: the same way we use datasets like MMLU and MMMU, etc. to evaluate language models, we use a small dataset like this and then experts are allowed to take the test and performance on the test is always public (and then you make a new test every month or year).

Maybe you also get some participants to do these questions in a quiz show format and put it on YouTube, so the test becomes more popular? I would watch that.

The disadvantage of this method compared to tests people prepare for in academia would be that the data would be quite noisy. On the other hand, this measure could be more robust to g... (read more)

2ChristianKl1y

If you have a best that actually measures expertise in engineering well, it's going to be valuable for those who make hiring decisions. Triplebyte essentially seems to have found a working business model that is about testing for expertise in programming. If you can do something similar as Triplebyte for other areas of expertise, that might be a good business model. As far as genius hedgehog's in academia go, currently they find it very hard to get funding for their ideas. If you would replace the current process of having to write a grant proposal with having to take a test to measure expertise, I would expect the diversity of ideas that get researched to increase.

7bhauth1y

Triplebyte? You mean, the software job interviewing company? 1. They had some scandal a while back where they made old profiles public without permission, and some other problems that I read about but can't remember now. 2. They didn't have a better way of measuring engineering expertise, they just did the same leetcode interviews that Google/etc did. They tried to be as similar as possible to existing hiring at multiple companies; the idea wasn't better evaluation but reducing redundant testing. But companies kind of like doing their own testing. 3. They're gone now, acquired by Karat. Which seems to be selling companies a way to make their own leetcode interviews using Triplebyte's system, thus defeating the original point.

Has anyone here investigated before if washing vegetables/fruits is worth it? Until recently I never washed my vegetables, because I classified that as a bullshit value claim.

Intuitively, if I am otherwise also not super hygienic (like washing my hands before eating) it doesn't seem that plausible to me that vegetables are where I am going to get infected from other people having touched the carrots etc... .

Cannot say this is a good source, but was a quick on. It does seem to speak to the question you're asking though so might be of interest. Might support the view that the additional produce you eat if not washing could out weigh the costs of the increased pesticide comsumption. But, I suspect that might be a very uncertain conclusion given the potential variability in factors regarding your specific situation -- where are the produce grown (what's in the soil), what pesticides, and what quantity, might be in use, what is the post harvesting process (any washing at all). The other aspect might be what consumption levels you have with and without washing. I am sure there is a level over which additional intake is adding little value. So if you're still eatting plenty of fresh produce even with the additional effor of washing you probably don't really need the additional nutriants (concentration levels in your body are already sufficient for the needed chemical reactions) but are avoiding things we know are not helpful to human biology.

While there is currently a lot of attention on assessing language models, it puzzles me that no one seems to be independently assessing the quality of different search engines and recommender systems. Shouldn't this be easy to do? The only thing I could find related to this is this Russian site (It might be propaganda from Yandex, as it is listed as the top quality site?). Taking their “overall search quality” rating at face value does seem to support the popular hypothesis that search quality of Google has slightly deteriorated over the last 10 years (alt...

Why do we have pimples/acne? Pimples are kind of a confusing phenomenon. As far as I can tell, a majority of people finds popping pimples compelling while knowing that this is obviously not "good for you" in the sense that you look worse afterwards, and if you just wait they often do in fact go away on their own again without risking an infection. My first thought was coming up with some lazy evolutionary psychology explanation that maybe popping pimples is so compelling because social grooming (Thinking of apes grooming each others backs) is good for you ...

One reason why I find Lesswrong valuable is that it serves as a sort of "wisdom feed" for myself, where I got exposed to a lot of great writing.

It is time that I apply the principle of more dakka and just start writing (or rather publishing) more. I know deliberate practice works for writing. If you want to be good at something, you need to do it badly and then just keep going with doing the thing is very common advice. I still find it very hard to do.

Things I ran into when writing before that stopped me:
- It's hard to decide what to write about
- I get anxiety about writing something that is not good enough
- Topics that go into my head about what to write about revolve mostly about how it is

3Viliam7mo

Ah, there is that weird relation between writing and publishing. On one hand, publishing gives you the incentive to write. On the other hand, publishing gives you the anxiety about writing. I have an intuition that a good solution to this would be some kind of multi-layered publishing system. Where you publish the article first to your close friends, and then if you feel okay about it, you promote it to larger audiences. At each step you can update the article; generally because you want to impress the larger audience more, but also based on the feedback from the previous audience. Probably each audience would have a separate comment section. At the first step, there would be no anxiety, because only your close friends will see it; and the next step, you would be encouraged by the feedback from the previous step. Something similar could be achieved by having two blogs, one only accessible for friends. Maybe as a mutual help, for a small group of bloggers who want to overcome their writing blocks. Yeah, that is a trap. Although you might write an article like that, without publishing it, as a therapy. By the way, some of my LW posts started as shortforms that grew too long, so I decided to publish them separately. This reduces the anxiety a lot, because as long as I am writing in the shortform editor, I don't really try to make it perfect. And when I switch to article form, I already have a large part of it written. I wonder, maybe I should try writing all my article ideas as shortforms. To start writing, and commit to publishing it today, either as a shortform or as an article, depending on how well the shortform writing will go.

I think more posts should be formatted as a nested list. They are especially clear, since indentation ≈ elaboration, which is not visible in continuous text.

2JustisMills7mo

Weekly has been feeling good to me, in terms of publishing! I write every day, but maybe 90% of it stays ~private lately. Weirdly, the most painful experience in a year of weekly posting is when a post of mine DID blow up! Attention ain't all you need after all. I am not sure if this random other person's experience is welcome, but I often struggle with little local peer group to viscerally ground what I should be doing, so, here's hoping it's nice for you (and bystanders!) to see.

I feel like there should exist a more advanced sequence that explains problems with filtered evidence leading to “confirmation bias”.

TLDR: I looked into how much it would take to fine-tune gpt-4 to do Fermi estimates better. If you liked the post/paper on fine-tuning Language models to make predictions you might like reading this. I evaluated gpt-4 on the first dataset I found, but gpt-4 was already making better fermi estimates than the examples in the dataset, so I stopped there (my code).

Probably silly

Quantifying uncertainty is great and all, but also exhausting precious mental energy. I am getting quite fond of giving probability ranges instead of point estimates when I want to communicate my uncertainty quickly. For example: “I'll probably (40-80%) show up to the party tonight.” For some reason, translating natural language uncertainty words into probability ranges feels more natural (at least to me) so requires less work for the writer.

If the difference is important, the other person can ask, but it still seems better than just saying 'probably'.

2Dagon3y

Interesting. For me, thinking/saying "about 60%" is less mental load and feels more natural than "40 to 80%". It avoids the rabbit-hole of what a range of probabilities even means - presumably that implies your probability estimates are normal around 60% with a standard deviation of 20%, or something. Is there anything your communication recipient would do differently with a range than a point estimate? presumably they care about the resolution of the event (will you attend) rather than the resolution of the "correct" probability estimate. There's a place for "no", "probably not", "maybe", "I hope to", "probably", "I think so", "almost certainly", and "yes" as a somewhat ambiguous estimate as well, but that's a separate discussion.

3Morpheus3y

Agree that the meaning of the ranges is very ill-defined. I think I am most often drawn to this when I have a few different heuristics that seem applicable. Example of internals: One is just how likely this feels when I query one of my predictive engines and another is just some very crude "outside view"/eyeballed statistic that estimates how well I did on this in the past. Weighing these against each other causes lots of cognitive dissonance for me, so I don't like doing it.

1Morpheus1y

I think from the perspective of a radical probabilist, it is very natural to not only have a word of where your current point estimate is at, but also have some tagging for the words indicating how much computation went into it or if this estimate already tries to take the listeners model into account also?

I am not sure how much this was a problem, but I felt like listening more to pop music on Spotify slowly led to value drift, because so many songs are about love and partying.

I felt a stronger desire to invest more time to fix the fact that I am single. I do not actually endorse that on reflection. The best solution I've found so far is starting to listen to music in languages I don't understand, which works great!

Practicing grammar and correcting grammar on the fly seem to be two different things. If you want to improve, then I would prompt GPT-4 with something like "I'm a student looking to improve my writing and grammar ability, here's an essay I wrote. Given that writing, please teach me about grammar."

Two weeks ago, I’ve been dissatisfied with the amount of workouts I do.

What is easier justify is using a prior that will actually converge, if there is any explanation at all (your observations aren't random noise)

Ok yeah. Logical induction just works then because you don't expect any adversaries in math truths.

I like the agreement voting feature for comments! Not only does it change incentives/signals people receive, I also notice how looking at whether to press this button I am more often actually asking myself whether I actually just endorse a comment or whether I actually belief it.

To say the obvious: make notes about what you learn. (I am not recommending any specific note-taking method here, only the general advice that a mediocre system you actually start using today is better than a hypothetically perfect system you only dream about.) It really sucks to spend a lot of time and work learning something, then not using it for a few years, then finding out you actually forgot everything. This usually doesn't happen at high school, because the elementary and high school education is designed as a spiral (you learn something, then four years later you learn the more advanced version of the thing). But at university: you may learn a thing once, and maybe never again. How much this means, you will only find out later, because it depends a lot on your specific school and classmates. I mean, it definitely means that you are good... but is it 1:100 good or 1:1000000 good? At high school both are impressive, but in later life you are going to compete against people who often also were the best in their classes.

3Morpheus4y

Update after a year: I am currently studying CS and I feel like I got kind of spoiled by reading "How to be a straight A student" which was mostly aimed at us-college students, and it was kind of hard to sort out which kinds of advice would apply in Germany and made the whole thing seem easier than it actually is. I am doing ok, but my grades aren't great (my best guess is that in pure grit+IQ I'm somewhere in the upper 40%). In the end, I decided that the value of this information wasn't so great after all, and now I am focusing more on how to actually gain career capital and getting better at prioritizing on a day-to-day basis.

If every private message on lesswrong or every cold email you ever wrote has received a response, you are either spending too much time writing them, are very young or aren't sending enough of them.

Is this an Umeshism?

1Roman Malov6mo

I would also add: if in the group chat your messages spark lots of conversation every time, this chat is underexploited (you are not sending enough/thinking too much). (Conversely, if your messages are ignored, spend a little bit more time on them)

1Roman Malov6mo

Why would that affect the frequency of the responses? How would receivers even deduce the age of the sender?

4Morpheus6mo

I was just trying to adjust a loophole that often seemed to be missing in Umeshisms, but I think this made my statement more confusing: if you are 15 years old (the particular age is irrelevant, I am just saying an age exists), then you having sent 1-2 cold emails is not too little, nor did you invest too much time, you are just young and there weren't that many worthy occasions yet. If you have just taken a single flight in your life and missed 0, this is not large evidence that you spend too much time at airports.

“Causality is part of the map, not the territory”. I think I had already internalized that this is true for probabilities, but not for “causality”, a concept that I don't have a solid grasp on yet. This should be sort of obvious. It's probably written somewhere in the sequences. But not realizing this made me very confused when thinking about causality in a deterministic setting after reading the post on finite factored sets in pictures (causality doesn't seem to make sense in a deterministic setting). Thanks to Lucius for making me realize this.

There isnt any strong reason to believe either "probability is in the map" or "causation is in the map", mainly because there aren't good reasons to believe it's a dichotomy.

Hm… maybe? Do you have a specific example, or links you have in mind when you say this? I am still having trouble wrapping my head around this and plan think more about it.

if you didn't get the idea from https://www.lesswrong.com/posts/f6ZLxEWaankRZ2Crv/probability-is-in-the-mind ...where did you get it from?

Yeah, I know, that post. I give Jaynes most of the credit for further corrupting me. Was mostly hoping for good links for how to think about causality. Something pointing towards the solution to the problems mentioned in this post. I kinda skimmed "The book of why", but did not feel like I really understood the motivation behind do-calculus. I still don't really understand the justification between saying that xyz are random variables. It seems like saying "these observations should all be bagged into the same variable X" is already doing huge legwork in terms of what is able to cause what. I kinda wonder whether you could do a thing similar to implications in logic where you say, "assuming we put these observations all in the same bag, that implies this bag causes this other bag to have a slightly different composition", but say we bag them a bit differently, and causation looks different.

Well, I responded to That Post, and you can tell it was good , because it was downvoted. Do you read the comments? Do you read non-rationalsphere material? It's not like the topic hasn't been extensively written about Its likely that mainstream won't tell you The Answer, but if there isn't an answer, you should wish to believe there is not an answer. You should not force yourself to "internalise" an answer you can't personally understand, and that has objections to it.

Wups...that might be a bug to fix. My excuse might be that I read the post before you made the comment, but I am not sure if that is true. I think you are definitely pointing out a failure mode I've fallen into recently, a few times. But mostly I am not sure if I understood what you mean. I also think my original comment failed to communicate how my views have actually shifted, which is mostly that after fidling with binary strings a bit and trying to figure out how I would model any causal chains in that, I noticed that the simple way I wanted to do that didn't work and my naive notion for how causes work broke down. I now think, when you have a system that is fully deterministic and that in such worlds "probabilistic causality" is a property of maps of such agents, but mostly I am still very confused. I don't actually have anything that I would call solution actually.

I made the comment over a year ago ... and the question was whether you read the comments in general. It should be obvious that if the territory is deterministic, the only remaining place for possibilities/probabilities to reside is in the map/mind. But it isn't at all obvious that the territory is deterministic.

I often do read the comments, though I don't really read that intentionally, so I don't have a good estimate of how often I read comments or how many I read (probably read most comments if I find the topic interesting, and I feel like the points in the post wasn't obvious before I read it). I scroll through the "Recent discussion" stuff almost never. So I miss a lot of comments if I read a post early on and then people make comments later that I never see.

The point is that there is often a good counterargument to whatever is being asserted in a post. Sometimes it's in a comment to the post itself -- which is easy and convenient-- and sometimes it's on another website,.or in a book. Either way,.rationality does not consist of forcing yourself to adopt a list of "correct" beliefs.
