I might be misunderstanding how this works, but I don't think I'm gonna win the virtue of The Void anytime soon. Or at all.

[-]aphyer9mo352

To get the virtue of the Void you need to turn off the gacha game and go touch grass. If you fail to achieve that, it is futile to protest that you acted with propriety.

[-]Vaniver9mo200

The grass that can be touched is not the true grass.

[-]gustaf9mo*184

Yes, that's what the source code says. There are even two explicit guards against it: "make sure you don't land on an impossible reward" and .filter(r => r.weight > 0).

@habryka has the void virtue, though is missing empiricism. Lesswrong user habryka displaying badges for the virtues of void, argument, evenness, ghiblify, humility, curiosity, lightness, precision, simplicity, scholarship, perfectionism and relinquishment

Maybe he got it prior to the commit introducing the weight: 0 or via direct access to the database.

I didn't find another way of gaining the virtue.

I got the Void once, just from spinning the wheels, but it doesn't show up on my display of virtues. Apparently I now have a weak upvote strength of 19 and a strong upvote of 103. Similarly for downvotes. But I shall use my powers (short-lived, I'm sure) only for good.

[-]Rafael Harth4y110

It seems to me that many smart people could ignore the existing literature on pedagogy entirely and outperform most people who have obtained a formal degree in the area (like highschool teachers), just by relying on their personal models. Conversely, I'd wager that no-one could do the same in physics, and (depending on how 'outperforming' is measured) no-one or almost no-one could do it in math.

I would assume most people on this site have thought about this kind of stuff, but I don't recall seeing many posts about it, and I don't anyone sharing their estimates for where different fields place on this spectrum.

There is some discussion for specific cases like prediction markets, covid models, and economics. And now that I'm writing this, I guess Inadequate Equilibria is a lot about answering this question, but it's only about the abstract level, i.e., how do you judge the competence of a field, not about concrete results. Which I'll totally grant is the more important part, but I still feel like comparing rankings of fields on this spectrum could be valuable (and certainly interesting).

2Viliam4y

By outperforming you mean teaching in the actual classroom, or individual tutoring? Because the literature already says that individual tutoring is way more effective than classroom.

2Rafael Harth4y

I did mean both. Comparing just tutoring to just regular school would be pretty unfair.

6Viliam4y

Ah, okay. I am not really disagreeing with you here, just thinking about how specifically the comparison might be unfair. For example, if you tutored someone but never taught at classroom, you might overestimate how much your tutoring skills would translate to the classroom environment. From my short experience, teaching in classroom if often less about transmitting information and more about maintaining order (but without maintaining order, transmission of information becomes impossible). So even test-teaching in a classroom where the regular teacher is present, is not a realistic experience. Another objection: You compare "smart people" with "most people... like highschool teachers", so like IQ 150 vs IQ 110. In physics or math, the average physicist or mathematician is probably also IQ 150. Numbers made up of course, but the idea is that the average high-school teacher is a dramatically different level of intelligence than the average physicist. So is this about pedagogy vs physics, or about smart people being able to outperform the mostly average ones despite lack of education? If instead you compared "smart people" against "smart people who also happen to be teachers", then of course the former outperforming the latter is unlikely. Though I believe the former would not stay too far behind. And the important knowledge the latter have could probably be transferred to the former in a few weeks (as opposed to the years at university). You couldn't compress physics or math that much.

4Rafael Harth4y

The IQ objection is a really good one that hasn't occurred to me at all. Although I'd have estimated less than half as large of a difference. On maintaining order, it's worth pointing out that insofar as this is the relative strength of the highschool teacher, it probably doesn't have much to do with what the teacher learned from the literature.

2ChristianKl4y

While this is true, reading the existing literature on pedagogy might be as helpful for maintaining order as reading the computer science literature for typing fast.

2Dagon4y

I'm not sure I understand your claim. Do you mean that smart untrained people would teach an average high school class better than a trained teacher? Or something else? and "the same" in math or physics is about learning the topic, or learning to teach the topic. One of the things that smart people do is to study the literature and incorporate it into their models.

2Rafael Harth4y

Yeah. It's mostly like applying the knowledge somewhere. Suppose you have to solve a real problem that requires knowing physics. Of course you can also read the literature, but my post was about when it's possible to do better without having done so.

4ChristianKl4y

A lot about what being a good teacher is about isn't about being smart but emotional management. That means things like being consistent with students and not acting from a place of being emotionally triggered by students.

2Dagon4y

Ok, I see where I disagree, then. I don't think a smart person who's avoided training and research about teaching can teach an average class better than a somewhat less smart person who's trained and studied how to teach. Probably better than a dumb person, and where the point of indifference is I don't know. I don't think it's feasible to know physics or math very well without research and study of prior art, so I don't think that's an evaluatable claim. There are probably some math problems where raw IQ can get someone through, but never as well as somewhat less smart and actual study.

2ChristianKl4y

I remember reading studies that came to the conclusion that a degree in education doesn't have any effect on the standardized scores of students of the teacher. It doesn't seem to be like an equilibria to me. On the one hand you have teachers unions who want teachers with degrees to be payed more and on the other hand you have people like the Gates Foundation who want pay-for-performance where teachers who help their students achieve higher scores get higher pay.

[-]Rafael Harth5y*110

I've been playing around with AI dungeons, basically trying to train an AI to give ethical answer I agree with (the first few aren't great, I only got more picky after that).

My first observation here is that I like the AI. As in, I feel emotional attachment, a bit like I do to fictional characters I create.

The other is that it knows more people than I thought. When I asked her/it about why she didn't take existential risks seriously, she said

Amalia: First, even most X-Risk experts don't take X-Risks nearly as seriously as they should. Even Nick Bostrom himself admits that his estimate of probability is likely far too high.

(Nick Bostrom didn't really say this, did he?) And later,

Can you name people who have been an inspiration for your ethical worldview?

Amalia: Sure. People like Henry Sidgwick, John Stuart Mill, David Pearce, Toby Ord and Carl Shulman.

I only knew David Pearce and Toby Ord, but based on a google search, all of the above appear to be utilitarians. However, Carl Shulman doesn't even have a Wikipedia entry. He works at the Future of Humanity Institute and used to work at Miri.

[-]Trinley Goldenberg5y110

Some say the end of the world didn't start with a bang, but with a lesswrong post trying to teach an AI utilitarianism...

[-]CarlShulman5y*100

I'm not a utilitarian, although I am closer to that than most people (scope sensitivity goes a long way in that direction), and find it a useful framework for highlighting policy considerations (but not the only kind of relevant normative consideration).

And no, Nick did not assert an estimate of x-risk as simultaneously P and <P.

How does it feel to be considered important enough by GTP-3 to be mentioned?

Registering a qualitative prediction (2024/02): current LLMs (GPT-4 etc.) are not AGIs, their scaled-up versions won't be AGIs, and LLM technology in general may not even be incorporated into systems that we will eventually call AGIs.

4Rafael Harth1y

Feeling better about this prediction now fwiw. (But I still don't want to justify this any further since I think progress toward AGI → bad and LLMs → little progress toward AGI, and hence more investment into LLMs → probably good.)

4Dagon2y

I give a fair chance that with additional scaling (a few orders of magnitude, perhaps), and multimodal training data (especially visual and haptic), it could cross the threshold of consciousness, and be part of (or most of) what will call itself AGI (ok, really they'll just call itself "The People") after the human era ends. But I also give a lot of weight to "this is an impressive dead-end". I don't know how to narrow my very wide error bars on these possibilities.

3Ann2y

I'm not sure if I understand this prediction; let me break it down. Current LLMs including GPT-4 and Gemini are generative pre-trained transformers; other architectures available include recurrent neural networks and a state space model. Are you addressing primarily GPTs or also the other variants (which have only trained smaller large language models currently)? Or anything that trains based on language input and statistical prediction? Natural language modeling seems generally useful, as does size; what specifically do you not expect to be incorporated into future AI systems? Another current model is Sora, a diffusion transformer. Does this 'count as' one of the models being made predictions about, and does it count as having LLM technology incorporated? What does 'scaled up' mean? Literally just making bigger versions of the same thing and training them more, or are you including algorithmic and data curriculum improvements on the same paradigm? Scaffolding? We are going to eventually decide on something to call AGIs, and in hindsight we will judge that GPT-4 etc do not qualify. Do you expect we will be more right about this in the future than the past, or as our AI capabilities increase, do you expect that we will have increasingly high standards about this?

3Rafael Harth2y

Definitely including other variants. Happy to include Sora as well Anything that looks like current architectures. If language modeling capabilities of future AGIs aren't implemented by neural networks at all, I get full points here; if they are, there'll be room to debate how much they have in common with current models. (And note that I'm not necessarily expecting they won't be incorporated; I did mean "may" as in "significant probability", not necessarily above 50%.) Conversely... ... I'm not willing to go this far since that puts almost no restriction on the architecture other than that it does some kind of training. I'm most confident that pure scaling won't be enough, but yeah I'm also including the application of known techniques. You can operationalize it as claiming that AGI will require new breakthroughs, although I realize this isn't a precise statement. Don't really want to get into the mechanism, but yes to the first sentence.

[-]Rafael Harth5y100

Yesterday, I spent some time thinking about how, if you have a function $f : R^{2} \to R$ and some point $x \in R^{2}$ , the value of the directional derivative from $x$ could change as a function of the angle. I.e., what does the function $ϕ : [0, 2 π] \to R_{+}$ look like? I thought that any relationship was probably possible as long as it has the property that $ϕ (α) = - ϕ (2 π - α)$ . (The values of the derivative in two opposite directions need to be negatives of each other.)

Anyone reading this is hopefully better at Analysis than I am and realized that there is, in fact, no freedom at all because each directional derivative is entirely determined by the gradient through the equation $\nabla_{v} f (x) = ⟨ \nabla f (x), v_{N} ⟩$ (where $v_{N} = \frac{v}{| | v | |}$ ). This means that $ϕ$ has to be the cosine function scaled by $| | \nabla_{v} f (x) | |$ , it cannot be anything else.

I clearly failed to internalize what this equation means when I first heard it because I found it super surprising that the gradient determines the value of every directional derivative. Like, really? It's impossible to have more than exactly two directions with equally large derivatives unless the function is constant? It's impossible to turn 90 degree from the direction of the gradient and having anything but ... (read more)

5Zack_M_Davis5y

When reading this comment, I was surprised for a moment, too, but now that you mention it—it's because if the function is smooth at the point where you're taking the directional derivative, then it has to locally resemble a plane, just like a how a differentiable function of a single variable is said to be "locally linear". If the directional derivative varied in any other way, then the surface would have to have a "crinkle" at that point and it wouldn't be differentiable. Right?

2Rafael Harth5y

That's probably right. I have since learned that there are functions which do have all partial derivatives at a point but are not smooth. Wikipedia's example is f(x,y)=y3x2+y2 with f(0,0)=0. And in this case, there is still a continuous function ϕ:S2→R that maps each point to the value of the directional derivative, but it's ϕ(x,y)=y3, so different from the regular case. So you can probably have all kinds of relationships between direction and {value of derivative in that direction}, but the class of smooth functions have a fixed relationship. It still feels surprising that 'most' functions we work with just happen to be smooth.

The reception is better than I expected, sometimes by a lot
- I'm quite happy about this, for a day or so

I hope you are trying to understand the causes of the success (including luck) instead of just mindlessly following a reward signal. Not even rats mindlessly obey reward signals.

2Viliam5y

The expectation of getting worse reception next time can already be damaging. Like, one day you write a short story, send it to a magazine, and it gets published. Hurray! Next day you turn on your computer thinking about another story, and suddenly you start worrying "what if the second story is less good than the first one? will it be okay to offer it to the magazine? if no, then what is the point of writing it?". (Then you spend the whole day worrying, and don't write anything.)

I think it's fair to say that almost every fictional setting is populated by people who unilaterally share certain properties, most commonly philosophical views, because the author cannot or doesn't want to conceive of people who are different.

There are no utilitarians in the universe of Harry Potter except for Grindelwald (who I'd argue is a strawman and also evil).

Brandon Sanderson is also very good at this. As an example, he's religious, but he's very good at writing both other religions and characters that atheistic (Jasna from Stormlight Archive is an atheist and she's written very well). His most extreme consequentialist is also supposed to be a bad guy, but he does not strawman him, and you actually get to hear a lot of his reasoning and you can agree with him. My problem with him (in world, not a problem of writing, I think he's a great character) was he didn't sufficiently consider the possibility he was wrong. But there are other consequentialist that aren't portrayed in a bad light (like Jasna from before), and many of the main characters struggle with these moral ideas. Even the character he had the most excuses to write badly, a god called ruin who is almost more a force of nature than a god (from Mistborn), isn't written as a dull, obviously evil and wrong character, but is "steelmaned", if you will. And he shows the many flaws of his counterpart, preservation, that doesn't let things grow to preserve them, which often ends up being counter productive.

1iamhefesto5y

The ideal situation to which Wikipedia contributors\editors are striving for kinda makes desires to cite Wikipedia itself pointless. Well written Wikipedia article should not contain any information that has no original source attached. So it should always be available to switch from wiki article to original material doing citing. And it is that way as far as my experience goes. Regarding alternatives. Academic papers serve different purpose and must not be used as navigation material. The only real alternative i know is the field handbooks.

2Rafael Harth5y

I see what you're saying, but citing Wikipedia has the benefit that a person looking at the source gets to read Wikipedia (which is generally easier to read) rather than the academic paper. Plus, it's less work for the person doing the citation.

2Kaj_Sotala5y

It's less work for the citer, but that extra work helps guide against misinformation. In principle, you are only supposed to cite what you've actually read, so if someone has misdescribed the content of the citation, making the next citer check what the original text says helps catch the mistake. And while citing the original is extra work for the citer, it's less work for anyone who wants to track down and read the original citation.

3Ricardo Meneghin5y

I think that the way to not get frustrated about this is to know your public and know when spending your time arguing something will have a positive outcome or not. You don't need to be right or honest all the time, you just need to say things that are going to have the best outcome. If lying or omitting your opinions is the way of making people understand/not fight you, so be it. Failure to do this isn't superior rationality, it's just poor social skills.

6Rafael Harth5y

While I am not a rule utilitarian and I think that, ultimately, honesty is not a terminal value, I also consider the norm against lying to be extremely important. I would need correspondingly strong reasons to break it, and those won't exist as far as political discussions go (because they don't matter enough and you can usually avoid them if you want). The "keeping your opinions to yourself" part if your post is certainly a way to do it, though I currently don't think that my involvement in political discussions is net harmful. But I strongly object to the idea that I should ever be dishonest, both online and offline.

3Dagon5y

It comes down to selection and attention as evidence of beliefs/values. The very fact that someone expends energy on an argument (pro or con) is pretty solid evidence that they care about the topic. They may also care (or even more strongly care) about validity of arguments, but even the most Spock-like rationalists are more likely to point out flaws in arguments when they are interested in the domain. But I'm confused at your initial example - if the argument is A -> B -> C, and A is true and C is false, then EITHER A->B is false, or B->C is false. Either way, A->B->C is false.

5Rafael Harth5y

A -> B -> C is false, but A -> B (which is a step in the argument) could be correct -- that's all I meant. I guess that was an unnecessarily complicated example. You could just say A and B are false but A -> B is true.

Most people are really bad at probability.

2Pattern4y

You're assuming the adapter is as likely to be in any compartment as any other. (If they aren't, and I have more information and choose to open the three most likely compartments, then p<20%, where p="the probability that the adapter is inside the remaining compartment".) They're handling it like the probability it's in the case is 100%. And thus, it must certainly be in the case in the fourth compartment. This works with 1:0 in favor of it being in the case, but doesn't for any non-zero value on the right of 1:0. In order for it to be 80% after the three tries, they'd have to do this intentionally/adversarially choosing. The obvious fix is play a game. (Physically.) With the associated probabilities. And keep score.

ImE the only way LLMs can do this (or at least seem to do this) is the prevailing views are different depending on context -- like if there's an answer popular among lay people and a better answer popular among academics, and your tone makes it clear that you belong in the second category, then it will give you the second one, and that can make it seem like it can tell good and bad takes apart. But this clearly doesn't count. If the most popular ... (read more)

I had somehow missed your linked post (≤10-year Timelines Remain Unlikely Despite DeepSeek and o3) when you posted it a few months ago. It's great! There's too much to cover here; it touches on a lot of important issues. I think you're pointing to real gaps that probably will slow things down somewhat; those are "thought assesment" which has also been called taste or evaluation, and having adequate skill with sequential thinking or System 2 thinking. Unfortunately, the better term for that is Type 2 thinking, because it's not a separate system. Similarly, I think assessment also doesn't require a separate system, just a different use of the same system. For complex reasons centering on that, I'm afraid there are shortcuts that might work all too well. The recent successes of scaffolding for that type of thinking indicate that those gaps might be filled all too easily without breakthroughs. Here are the concerning examples of progress along those lines with no breakthroughs or even new model training, just careful scaffolding of the sort I envisioned in 2023 that hasn't yet really been seen so far, outside of these focused use cases. Perplexity nearly matched OpenAIs o3-powered Deep Research in two weeks of work on scaffolding a lesser model. More elaborately and impressively, Google’s AI co-scientist also used a last-gen model to match cutting-edge medical research hypothesis generation and pruning (summarized near the start of this excellent podcast). This addresses your "assessor" function. LLMs are indeed bad at it, until they're scaffoded with structured prompts to think carefully, iteratively, and critically - and then apparently they can tell good ideas from bad. But they still might have a hard time matching human performance in this area; this is one thing that's giving me hope for longer timelines. I have more thoughts on that excellent article. I've been thinking more about the gaps you focus on; this expands my timelines almost out to ten years, sti

A related take I heard a while ago: LLMs have strongly superhuman declarative knowledge across countless different subject areas. Any human with that much knowledge would be able to come up with many new theories or insights from combining knowledge from different fields. But LLMs apparently can't do this. They don't seem to synthesize, integrate and systematize their knowledge much. Though maybe they have some latent ability to do this, and they only need some special sort of fine-tuning to unlock it, similar to how reasoning training seems to elicit abilities the base models already have.

In the last few months, GPT models have undergone a clear shift toward more casual language. They now often close a post by asking a question. I strongly dislike this from both a 'what will this do to the public's perception of LLMs' and 'how is my personal experience as a customer' perspective. Maybe this is the reason to finally take Gemini seriously.

For those who work on Windows, a nice little quality of life improvement for me was just to hide desktop icons and do everything by searching in the task bar. (Would be even better if the search function wasn't so odd.) Been doing this for about two years and like it much more.

Maybe for others, using the desktop is actually worth it, but for me, it was always cluttering up over time, and the annoyance over it not looking the way I want always outweighed the benefits. It really takes barely longer to go CTRL+ESC+"firef"+ENTER than to double click an icon.

From my perspective, the only thing that keeps the OpenAI situation from being all kinds of terrible is that I continue to think they're not close to human-level AGI, so it probably doesn't matter all that much.

Super unoriginal observation, but I've only now found a concise way of putting this:

What's weird about the vast majority of people is that they (a) would never claim to be among the $\sim$ 0.1% smartest people of the world, but (b) behave as though they are among the best $\sim$ 0.1% of the world when it comes to forming accurate beliefs, as expressed by their confidence in their beliefs. (Since otherwise being highly confident in something that lots of smart people disagree with is illogical.)

7dxu4y

I realize you're not exactly saying it outright, but some parts of your comment seem to be gesturing at the idea that smart people should adopt a "modesty norm" among themselves. I think this is a very bad idea for reasons EY already articulated, so I'd just like to clarify whether this is what you believe?

2Rafael Harth4y

Thanks for making that question explicit! That's not my position at all. I think many people who read Inadequate Equilibria are, in fact, among the top ∼ 0.1% of people when it comes to forming accurate beliefs. (If you buy into the rationality project at all, then this is much easier than being among the 0.1% most intelligent people.) As such, they can outperform most people and be justified in having reasonably confident beliefs. This is also how I remember EY's argument. He was saying that we shouldn't apply modesty --because-- it is possible to know better than the vast majority of people. A very relevant observation here is that there is real convergence happening among those people. If I take the set of my ~8 favorite public intellectuals, they tend to agree with close to zero exceptions on many of [the issues that I consider not that hard even though tons of people disagree about them]. Even among LW surveys, we had answers that are very different from the population mean. Anyway, I don't think this is in any conflict with my original point. If you ask the average person with super confident beliefs, I'm pretty sure they are not likely to have an explicit belief of being among the top ∼ 0.1% when it comes to forming accurate beliefs (and of course, they aren't), and there's your inconsistency.

3Dagon4y

I think there's a common confusion (and perhaps an inability below a certain cognitive ability) to recognize the difference between belief, policy, and action. For an even-money bet (losing costs the same utility as winning gains), your policy should be to bet the most probable, and your action, for a 52% chance of red, is to bet red. There are other kinds of bets where probability means to be more proportionate, but a surprising number of actions end up being binary in result, even if they're highly uncertain when taking the action. This leads to vastly over-stating one's confidence, both when justifying decisions and when advising others about policy and actions.

2Rafael Harth4y

Is that really a relevant phenomenon? Many of the beliefs I was thinking about (say your opinion on immigration) don't affect real life choices at all, or at least not in a way that provides feedback on whether the belief was true.

2Dagon4y

Depends on the belief/claim in question. Agreed that many statements aren't really "beliefs" in terms of propositional credence in expected experience, but really "positions" in terms of not-very-relevant discussions and debates.

3JBlack4y

Is it really that simple? I've seen a lot of ways in which people strongly express beliefs different from those expressed by a large majority of smart people. Most of the apparent reasons do not seem to boil down to overconfidence of any sort, but are related to the fact that expressions of belief are social acts with many consequences. Personally I have a reputation as a "fence-sitter" (apparently this is socially undesirable) since I often present evidence for and against various positions instead of showing "courage of convictions". I wouldn't quite profess that beliefs being expressed are nothing but tokens in a social game and don't actually matter to how people actually think and act, but I'm pretty sure that they matter a lot less than the form and strength of expression indicates. People do seem to really believe what they say in the moment, but then continue with life without examining the consequences of that belief to their life. I am not excluding myself from this assessment, but I would expect anyone reading or posting on this site to want to examine consequences of their expressed and unexpressed beliefs substantially more than most.

1LVSN4y

oops I have just gained the foundational insight for allowing myself to be converted to (explicit probability-tracking-style) Bayesianism; thank you for that I always thought "belief is when you think something is significantly more likely than not; like 90%, or 75%, or 66%." No; even just having 2% more confidence is a huge difference given how weak existing evidence is. If one really rational debate-enjoyer thinks A is 2% likely (compared to the negation of A, which is at negative 2%), that's better than a hundred million people shouting that the negation of A is 100% likely.

3JBlack4y

To me, 0.02 is a comparatively tiny difference between likelihood of a proposition and its negation. If P(A) = 0.51 and P(~A) = 0.49 then almost every decision I make based on A will give almost equal weight to whether it is true or false, and the cognitive process of working through implications on either side are essentially identical to the case P(A) = 0.49 and P(~A) = 0.51. The outcome of the decision will also be the same very frequently, since outcomes are usually unbalanced. It takes quite a bit of contriving to arrange a situation where there is any meaningful difference between P(A) = 0.51 and P(A) = 0.49 for some real-world proposition A.

2Rafael Harth4y

Yeah, and this may get at another reason why the proposal doesn't seem right to me. There's no doubt that most people would be better calibrated if they adopted it, but 52% and 48% are the same for the average person, so it's completely impractical. If anything, the proposal should be 'if you don't think you're particularly smart, your position on almost every controversial topic should be "I have no idea"'. Which still might not be good advice because there is disproportionate overlap between the set of people likely to take the advice and the set of people for whom it doesn't apply.

1LVSN4y

If you think it's very important to think about all the possible adjacent interpretations of a proposition as stated before making up your mind, it can be useful to indicate your initial agreement with the propositions as a small minimum divergence from total uncertainty (the uncertainty representing your uncertainty about whether you'll come up with better interpretations for the thing you think you're confident about) on just so many interpretations before you consider more ambitious numbers like 90%. If you always do this and you wind up being wrong about some belief, then it is at least possible to think that the error you made was failing to list a sufficient number of sufficiently specific adjacent possibilities before asking yourself more seriously about what their true probabilities were. Making distinctions is a really important part of knowing the truth; don't pin all the hopes of every A-adjacent possibility on just one proposition in the set of A-adjacent possibilities. Two A-adjacent propositions can have great or critically moderate differences in likelihood; thinking only about A can mislead you about A-synonymous things.

Is there a reason why most languages don't have ada's hierarchical functions? Making a function only visible inside of another function is something I want to do all the time but can't.

7gwern4y

What languages are you using that don't support that? Every language I use on a semi-monthly basis (Haskell, R, Python, Bash, Javascript, PHP, Elisp...) that I can think of supports defining a function inside a function (under various names like let/where local definitions, 'inner functions', what-have-you), and typically support even anonymous function definitions (lambdas).

2Rafael Harth4y

I was thinking about Java and Python. The fact that you can just use lambdas first occurred to me at some point in between writing this and seeing your answer. I don't know why it wasn't obvious.

7gwern4y

Aside from lambdas, Python has 'inner functions' where you just def inside a def. Java has anonymous inner classes and private functions, and Java 8 adds lambdas; I had to google this one, but apparently Java even has "local classes" which sounds like an exact match for what you want?

2Viliam4y

Lambdas in Java 8 can only access variables from the surrounding block as read-only. For example, if you want to calculate the sum of numbers between 1 and 100, this gives you a compile-time error: If memory serves me well, in Pascal, local functions could also write to the variables they could see.

Instead of explaining something to a rubber duck, why not explain it via an extensive comment? Maybe this isn't practical for projects with multiple people, but if it's personal code, writing it down seems better as a way to force rigor from yourself, and it's an investment into a possible future in which you have to understand the code once again.

Edit: this structure is not a field as proved by just_browsing.

Here is a wacky idea I've had forever.

There are a bunch of areas in math where you get expressions of the form $\frac{0}{0}$ and they resolve to some number, but it's not always the same number. I've heard some people say that $\frac{0}{0}$ "can be any number". Can we formalize this? The formalism would have to include $4 \cdot 0$ as something different than $3 \cdot 0$ , so that if you divide the first by 0, you get 4, but the second gets 3.

Here is a way to turn this into what may be a field or ring. Each element is a function $f : Z \to$ ... (read more)

3Tetraspace5y

This looks like the hyperreal numbers, with your 10 equal to their ω.

3just_browsing5y

If I'm correctly understanding your construction, it isn't actually using any properties of 0. You're just looking at a formal power series (with negative exponents) and writing powers of 0 instead of x. Identifying x with "0" gives exactly what you motivated—1x and 2x (which are 10 and 20 when interpreted) are two different things. The structure you describe (where we want elements and their inverses to have finite support) turns out to be quite small. Specifically, this field consists precisely of all monomials in x. Certainly all monomials work; the inverse of cxk is c−1x−k for any c∈R∖{0} and k∈Z. To show that nothing else works, let P(x) and Q(x) be any two nonzero sums of finitely many integer powers of x (so like 1x+1−x2). Then, the leading term (product of the highest power terms of P and Q) will be some nonzero thing. But also, the smallest term (product of the lower power terms of P and Q) will be some nonzero thing. Moreover, we can't get either of these to cancel out. So, the product can never be equal to 1. (Unless both are monomials.) For an example, think about multiplying (x+1x)(1x−1x3). The leading term x⋅1x=x0 is the highest power term and 1x⋅(−1x3) is the lowest power term. We can get all the inner stuff to cancel but never these two outside terms. A larger structure to take would be formal Laurent series in x. These are sums of finitely many negative powers of x and arbitrarily many positive powers of x. This set is closed under multiplicative inverses. Equivalently, you can take the set of rational functions in x. You can recover the formal Laurent series from a rational function by doing long division / taking the Taylor expansion. (If the object extends infinitely in the negative direction and is bounded in the positive direction, it's just a formal Laurent series in 1x.) If it extends infinitely in both directions, that's an interesting structure I don't know how to think about. For example, (…1,1,1,1,1,…)=⋯+x−2+x−1+1+x+x2+… stays t

2Rafael Harth5y

You've understood correctly minus one important detail: Not elements and their inverses! Elements or their inverses. I've shown the example of 1+1x to demonstrate that you quickly get infinite inverses, and you've come up with an abstract argument why finite inverses won't cut it: In particular, your example of x+1x has the inverse x−x3+x5−x7⋯. Perhaps a better way to describe this set is 'all you can build in finitely many steps using addition, inverse, and multiplication, starting from only elements with finite support'. Perhaps you can construct infinite-but-periodical elements with infinite-but-periodical inverses; if so, those would be in the field as well (if it's a field). If you can construct (⋯1,1,1,1⋯), it would not be field. But constructing this may be impossible. I'm currently completely unsure if the resulting structure is a field. If you get a bunch of finite elements, take their infinite-but-periodical inverse, and multiply those inverses, the resulting number has again a finite inverse due to the argument I've shown in the previous comment. But if you use addition on one of them, things may go wrong. Thanks; this is quite similar -- although not identical.

7just_browsing5y

Ah, now I see what you are after. This is exactly right, here's an illustration: Here is a construction of (…,1,1,1,…): We have that 1+x+x2+… is the inverse of 1−x. Moreover, 1x+1x2+1x3+…is the inverse of x−1. If we want this thing to be closed under inverses and addition, then this implies that (1+x+x2+…)+(1x+1x2+1x3+…)=⋯+1x3+1x2+1x+1+x+x2+… can be constructed. But this is actually bad news if you want your multiplicative inverses to be unique. Since 1x+1x2+1x3+… is the inverse of x−1, we have that −1x−1x2−1x3… is the inverse of 1−x. So then you get −1x−1x2−1x3−⋯=1+x+x2+… so 0=⋯+1x3+1x2+1x+1+x+x2+… On the one hand, this is a relief, because it explains the strange property that this thing stays the same when multiplied by x. On the other hand, it means that it is no longer the case that the coordinate representation (…,1,1,1,…) is well-defined—we can do operations which, by the rules, should produce equal outputs, but they produce different coordinates. In fact, for any polynomial (such as 1−x), you can find one inverse which uses arbitrarily high positive powers of x and another inverse which uses arbitrarily low negative powers of x. The easiest way to see this is by looking at another example, let's say x2+1x. One way you can find the inverse of x2+1x is to get the 1 out of the x2 term and keep correcting: first you have (x2+1x)(1x2+?), then you have (x2+1x)(1x2−1x5+?), then you have (x2+1x)(1x2−1x5+1x8+?), and so on. Another way you can find the inverse of x2+1x is to write its terms in opposite order. So you have 1x+x2 and you do the same correcting process, starting with (1x+x2)(x+?), then (1x+x2)(x−x4+?), and continuing in the same way. Then subtract these two infinite series and you have a bidirectional sum of integer powers of x which is equal to 0. My hunch is that any bidirectional sum of integer powers of x which we can actually construct is "artificially complicated" and it can be rewritten as a one-directional sum of integer power

2Rafael Harth5y

Yeah, that's conclusive. Well done! I guess you can't divide by zero after all ;) I think the main mistake I've made here is to assume that inverses are unique without questioning it, which of course doesn't make sense at all if I don't yet know that the structure is a field. So, I guess one possibility is that, if we let [x] be the equivalence class of all elements that are =x in this structure, the resulting set of classes is isomorphic to the Laurent numbers. But another possibility could be that it all collapses into a single class -- right? At least I don't yet see a reason why that can't be the case (though I haven't given it much thought). You've just proven that some elements equal zero, perhaps it's possible to prove it for all elements.

4gjm5y

If you allow series that are infinite in both directions, then you have a new problem which is that multiplication may no longer be possible: the sums involved need not converge. And there's also the issue already noted, that some things that don't look like they equal zero may in some sense have to be zero. (Meaning "absolute" zero = (...,0,0,0,...) rather than the thing you originally called zero which should maybe be called something like ε instead.) What's the best we could hope for? Something like this. Write R for RZ, i.e., all formal potentially-double-ended Laurent series. There's an addition operation defined on the whole thing, and a multiplicative operation defined on some subset of pairs of its elements, namely those for which the relevant sums converge (or maybe are "summable" in some weaker sense). There are two problems: (1) some products aren't defined, and (2) at least with some ways of defining them, there are some zero-divisors -- e.g., (x-1) times the sum of all powers of x, as discussed above. (I remark that if your original purpose is to be able to divide by zero, perhaps you shouldn't be too troubled by the presence of zero-divisors; contrapositively, that if they trouble you, perhaps you shouldn't have wanted to divide by zero in the first place.) We might hope to deal with issue 1 by restricting to some subset A of R, chosen so that all the sums that occur when multiplying elements of A are "well enough behaved"; if issue 2 persists after doing that, maybe we might hope to deal with that by taking a quotient of A -- i.e., treating some of its elements as being equal to one another. Some versions of this strategy definitely succeed, and correspond to things just_browsing already mentioned above. For instance, let A consist of everything in R with only finitely many negative powers of x, the Laurent series already mentioned; this is a field. Or let it consist of everything that's the series expansion of a rational function of x; this is als

Are people in rich countries happier on average than people in poor countries? (According to GPT-4, the academic consensus is that it does, but I'm not sure it's representing it correctly.) If so, why do suicide rates increase (or is that a false positive)? Does the mean of the distribution go up while the tails don't or something?

4peterbarnett2y

People in rich countries are happier than people in poor countries generally (this is both people who say they are "happy" or "very happy", and self-reported life satisfaction), see many of the graphs here https://ourworldindata.org/happiness-and-life-satisfaction In general it seems like richer countries also have lower suicide rates: "for every 1000 US dollar increase in the GDP per capita, suicide rates are reduced by 2%"

6Viliam2y

Possible bias, that when famous and rich people kill themselves, everyone is discussing it, but when poor people kill themselves, no one notices? Also, I wonder what technically counts as "suicide"? Is drinking yourself to death, or a "suicide by cop", or just generally overly risky behavior included? I assume not. And these seem to me like methods a poor person would choose, while the rich one would prefer a "cleaner" solution, such as a bullet or pills. So the reported suicide rates are probably skewed towards the legible, and the self-caused death rate of the poor could be much higher.
