You would be deceiving someone regarding the strength of your belief. You know your belief is far weaker than can be supported by your statement, and in our general understanding of language a simple statement like 'X is happening tonight' is interpreted as having a strong degree of belief. 

If you actually truly disagree with that, then it wouldn't be deception, it would be miscommunication, but then again I don't think someone who has trouble assessing approximate Bayesian belief from simple statements would be able to function in society at all.

A minor point, perhaps a nitpick: both biological systems and electronic ones depend on directed diffusion. In our bodies diffusion is often directed by chemical potentials, and in electronics it is directed by electric or vector potentials. It's the strength of the 'direction' versus the strength of the diffusion that makes the difference. (See: https://en.m.wikipedia.org/wiki/Diffusion_current)

Except in superconductors, of course.

So the reason why the time value of money works, and it makes sense to say that we can say that the utility of $1000 today and $1050 in a year are about the same, is because of the existence of the wider financial system. In other words, this isn't necessarily true in a vacuum; however if I wanted $1050 in a year, I can invest the $1000 I have right now into 1 year treasuries. The converse is more complex; if I am guaranteed $1050 in a year I may not be able to get a loan for $1000 right now from a bank because I'm not the fed and loans to me have a higher... (read more)

I think this is precisely what "equal utility" means in context. To be clear, in this post I'm trying to talk about expected utility maximizers, the simple mathematical abstraction of "agent who has a utility function (which satisfies certain technical conditions) and attempts to maximize its expected value". And the reason I'm trying to talk about that type of agent is because I think the things I'm replying to are also trying to talk about that type of agent. Possibly it would be clearer to simply leave "money" out of it, but reusing examples from prior art seems useful. Also I think it makes the post less dry. Perhaps I should have started with a big disclaimer that I'm trying to talk about expected utility maximizers and references to a thing labeled "money" are not intended to invoke concepts like "global economy" or "purchasing goods and services". I'm talking about a hypothetical agent who values this thing labeled "money" for its own sake. The reason I'm talking about that type of agent is because I think understanding that type of agent can be useful when we try to think about more-realistic agents, who more-realistically value a real-world thing called "money" that exists in a global economy and can be used to purchase goods and services. But those more-realistic agents, and that more-realistic money, are not what I'm talking about currently. And I'm not here trying to justify why I think that can be useful. (Or maybe the things I'm replying to aren't trying to talk about that type of agent, they just use words like "expected utility" without intending to point at their technical definition and that confuses things. But if that's the case, then I'm probably not the only person who thinks that's what they're trying to talk about; and so it still seems good for me to clarify what happens with that type of agent, in the sort of situation in question.) (Probably it would be good for me to find some examples of the things I'm responding to, but that would

Regarding overconfidence, GPT-4 is actually very very well-calibrated before RLHF post-training (see paper Fig. 8). I would not be surprised if the RLHF processes imparted other biases too, perhaps even in the human direction.

2Kevin Dorst
Nice point! Thanks.  Hadn't thought about that properly, so let's see.  Three relevant thoughts: 1) For any probabilistic but non-omniscient agent, you can design tests on which it's poorly calibrated on.  (Let its probability function be P, and let W = {q: P(q) > 0.5 & ¬q} be the set of things it's more than 50% confident in but are false.  If your test is {{q,¬q}: q ∈ W}, then the agent will have probability above 50% in all its answers, but its hit rate will be 0%.)  So it doesn't really make sense to say that a system is calibrated or not FULL STOP, but rather that it is (or is not) on a given set of questions.   What they showed in that document is that for the target test, calibration gets worse after RLHF, but that doesn't imply that calibration is worse on other questions.  So I think we should have some caution in generalizing. 2) If I'm reading it right, it looks like on the exact same test, RLHF significantly improved GPT4's accuracy (Figure 7, just above).  So that complicates that "merely introducing human biases" interpretation. 3) Presumably GPT4 after RLHF is a more useful system than GPT4 without it, otherwise they would have released a different version.  That's consistent with the picture that lots of fallacies (like the conjunction fallacy) arise out of useful and efficient ways of communicating (I'm thinking of Gricean/pragmatic explanations of the CF).

Remember, the "exception throwing" behavior involves taking the entire space of outcomes and splitting it into two things: "Normal" and "Error." If we say this is what we ought to do in the general case, that's basically saying this binary property is inherent in the structure of the universe.

I think your view involves a bit of catastrophizing, or relying on broadly pessimistic predictions about the performance of others.  Remember, the "exception throwing" behavior involves taking the entire space of outcomes and splitting it into two things: "Normal" and "Error." If we say this is what we ought to do in the general case, that's basically saying this binary property is inherent in the structure of the universe.  But we know that there's no phenomenon that can be said to actually be an "error" in some absolute, metaphysical sense. This is an arbitrary decision that we make: We choose to abort the process and destroy work in progress when the range of observations falls outside of a single threshold.  This only makes sense if we also believe that sending the possibly malformed output to the next stage in the work creates a snowball effect or an out-of-control process.  There are probably environments where that is the case. But I don't think that it is the default case nor is it one that we'd want to engineer into our environment if we have any choice over that - which I believe we do.  If the entire pipeline is made of checkpoints where exceptions can be thrown, then if I remove an earlier checkpoint, then it could mean that more time is wasted if it is destined to be thrown at a later time. But like I mentioned in the post, I usually think this is better, because I get more data about what the malformed input/output does to later steps in the process. Also, of course, if I remove all of the checkpoints, then it's no longer going to be wasted work.  Mapping states to a binary range is a projection which loses information. If I instead tell you, "This is what I know, this is how much I know it," that seems better because it carries enough to still give you the projection if you wanted that, plus additional information. I don't know if I agree that those things have anything to do with people tolerating probability and using calibration to continue

I think I know what you mean, but personally I'd try to avoid talking about utility functions here. A utility function is the thing one optimizes with respect to, trying to choose an "optimal utility function" suggests you have something outside the utility function that you value, and in that case it's not really a utility function. That said I'm not sure how I would ask the question myself. Maybe something about optimal levels of risk aversion? So this doesn't really deal with the problem I'm thinking of. I think what you're thinking is: instead of having a utility function that's (say) linear in money, you'd have it be linear in money and negative-exponential in time. So instead of U(m)=m, you'd have something isomorphic to U(m,t)=m⋅2−t. And so U(1,0)=U(2,1)=1. But does that mean such an agent is indifferent between receiving £0.01 now and £0.02 in a second? That's not obvious to me, because if they're making the decision at time 0 they need to choose between "Utility U(1,0)=1 now and utility U(1,1)=1/2 in one second"; and "utility U(0,0)=0 now and utility U(2,1)=1 in one second". Which do they choose? The fact that the "now" in one choice equals the "later" in another doesn't answer that question for me. (We can postulate that they might be able to use £0.01 at time 0 to have more than £0.01 at time 1. But that makes things more complicated, not less. I feel like if we want to claim we can answer questions about expected utility maximizers, we should be able to answer them in simple situations.) And then there are even weirder cases, like what if we have an agent whose utility is U(m,t)=msin(t)? I can imagine answers like "you integrate the utility function over all of time" or "you take the max value" or "the limit as t→∞", but then it seems to me that that is the actual utility function? And also all of those possibilities will diverge in a lot possible situations. Now that I bring this up I have a vague feeling I've seen this sort of thing discussed? (

I come from science, so heavy scientific computing bias here.

I think you're largely focusing on the wrong metric. Whether exceptions should be thrown has little to do with reliability (and indeed, exceptions can be detrimental to reliability), but instead is more related to correctness. They are not always the same thing. In a scientific computing context, for example, a program can be unreliable, with memory leaks resulting in processes often being killed by the OS, but still always give correct results when a computation actually manages to finish.

This is a good reply, because its objections are close to things I already expect will be cruxes.  Yeah, I'm interested in why we need strong guarantees of correctness in some contexts but not others, especially if we have control over that aspect of the system we're building as well. If we have choice over how much the system itself cares about errors, then I can design the system to be more robust to failure if I want it to be. I think the crux for me here is how long it takes before people notice that the belief in a wrong result causes them to receive further wrong results, null results, or reach dead-ends, and then causes them to update their wrong belief. LK-99 is the most recent instance that I have in memory (there aren't that many that I can recall, at least).  What's the worst that happened from having false hope? Well, researchers spent time simulating and modeling the structure of it and tried to figure out if there was any possible pathway to superconductivity. There were several replication attempts. If that researcher-time-money is more valuable (meaning potentially more to lose), then that could be because the researcher quality is high, the time spent is long, or the money spent is very high.  If the researcher quality is high (and they spent time doing this rather than something else), then presumably we also get better replication attempts, as well as more solid simulations / models. If they debunk it, then those are more reliable debunks. This prevents more researcher-time-money from being spent on it in the future. If they don't debunk it, that signal is more reliable, and so spending more on this is less likely to be a waste. If researcher quality is low, then researcher-time-money may also be low, and thus there will be less that could be potentially wasted. I think the risk we are trying to avoid is losing high-quality researcher time that could be spent on other things. But if our highest-quality researchers also do high-quality debunki

How would you experimentally realise mechanism 1? It still feels like you need an additional mechanism to capture the energy, and it doesn't necessarily seems easier to experimentally realise.

With regards to 2, you don't necessarily need a thermal bath to jump states, right? You can just emit a photon or something. Even in the limit where you can fully harvest energy, thermodynamics is fully preserved. If all the energy is thermalised, you actually cannot necessarily recover Landauer's principle; my understanding is that because of thermodynamics, even if you don't thermalise all of that energy immediately and somehow harvest it, you still can't exceed Landauer's principle.

1DaemonicSigil
One example (probably not the easiest thing to implement in practice) is the charge-patterned wheel that I mentioned in my thread with Jacob. If we're lowing the energy of a state while the particle is in that state, then the potential gradient puts a force on the particle which pulls back on the wheel, increasing its energy. If you're emitting into vacuum (no other photons there at all), then that's like having access to a thermal bath of temperature 0. Erasure can be done for arbitrarily low cost under such conditions. If the vacuum has temperature higher than 0, then it has some photons in it and occasionally one of them will come along and knock into our particle. So then we pretty much have a thermal bath again.
qjh10

I don't buy your ~kT argument. You can make the temperature ratio arbitrarily large, and hence the energy arbitrarily small, as far as I understand your argument.

With your model, I don't understand why the energy 'generated' when swapping isn't thermalised (lost to heat). When you drop the energy of the destination state and the particle moves from your origin to your destination state, the energy 'generated' seems analogous to that from bit erasure; after all, bit erasure is moving a particle between states (50% of the time). If you have a mechanism for h... (read more)

1DaemonicSigil
There's some intrinsic energy required to erase a bit, kTlog2. This is true no matter how large the temperature ratio is. The point is that we'd normally be paying some extra energy cost in addition to this kTlog2 in order to get the particle over the energy wall, and it's this that we can make arbitrarily small by changing the temperature ratio. Overall, I'd say that the "simple straightforward argument" serves mostly as an intuition pump for the idea that a high energy wall is needed only during computation and not erasure. It won't convince a skeptical reader, the computational study is in the post because it's actually pretty important. Basically, there's two ways the energy of the particle can be lowered: 1. Lower the energy of a state while the particle is sitting in that state. This energy is recaptured by you. 2. Due to interaction with the environment, which has lots of thermal noise, the particle jumps from a high-energy state to a low energy state. This energy is dissipated and not recaptured by you. When we're lowering the energy of the destination state, we're recapturing energy through mechanism 1. The process is basically the reverse of a Landauer erasure. We're accepting a bit of thermal noise from the environment in exchange for being given a little less than kTlog2 of energy. Then in the reverse phase we spend a little more than kTlog2 to push that bit back into the environment. Anyways, this model can be shown to still respect the Landauer limit. See this. If you perform the process very slowly such that the probability distribution over states matches the Boltzmann distribution then the energy cost integral gives kTlog2.

I predict most people will have an easier time reading the second one that the first one, holding their jargon-familiarity constant. (the jargon basically isn't at all a crux for me at all) (I bet if we arranged some kind of reading comprehension test you would turn out to do better at reading-comprehension for paragraph-broken abstracts vs single-block abstracts. I'd bet this at like 70% confidence for you-specifically, and... like 97% confidence for most college-educated people) A few reasons I expect this to be true (other than just generalizing from my example and hearing a bunch of people complain about Big Blocks of Text) Keeping track of where you are in the text. If you're reading a long block of text, and then get distracted for any reason, you have to relocate where you left off to keep reading. A long block of text doesn't give you any hand-holds for doing that. Pausing and digesting I (and I think most people) can only digest so much information at once. Paragraph breaks are a way for the author to signal "here is a place you might want to pause briefly and consolidate your thoughts slightly before moving on." The paragraph-break is a both a signal that "now is maybe a time to do that", and it also helps you avoid losing your place after doing so (see previous section) Skimming Often when I start reading a paragraph, I'm like "okay, I roughly get this. I don't really need to fully absorb this info, I want to move on to the next bit." This could be either because I'm hunting for a specific set of information, or because I'm just trying to build up a high-level understanding of what the text is saying before reading it thoroughly. Paragraphs give me some hand-holds for skimming, because they typically group information in a sensible way.

I agree with your comment, but I think the definitional problem is core to the debate rather than something that can simply be discarded. Consumerism is not consumption, but it used to mean consumer protection and empowerment (obviously there is a spectrum there about what constitutes adequate information and the appropriate regulations/interventions to ensure that)...in support of their consumption, which was assumed to be valuable for them. Consumerism has taken on a second, more prominent meaning that itself is a spectrum: sometimes demanding the pricing/regulation of externality-generating production (not all that different in nature from economics, but unique in the externalities that are identified, oftentimes private costs that consumers simply don't attend to), sometimes all the way to value judgments about certain kinds of consumption. It's such a loaded term I find it best instead to talk about what I actually mean rather than use the term consumerism. Do I want to talk about negative aspects of consumption? Do I want to talk about the consumer information movement? Which one am I about to get into when I say "I'd like to talk about consumerism"? I also want to add to your bolded comment on substitution, which seems like a really good rule of thumb. But a lot of things cannot be substituted easily because they are timing- or situation-dependent. If I have 15 minutes to kill, it's not obvious that just sitting there with my thoughts is particularly desirable (for some people, sure!), so I'll seek to consume something (not non-consumption) - if the park is 2.5 minutes away, I can consume a 10 minute walk at the park, which might dominate my crappy phone game. If the park is 7.5 minutes away, I can consume a walk to the park, but given that menu of options, maybe my phone game is fine.

Japanese TFR actually has had a bit of a reversal since 2005: https://data.worldbank.org/indicator/SP.DYN.TFRT.IN?end=2020&locations=JP&start=1960&view=chart

The trend started going back down again, but I think short term trends are unreliable especially with the economic upheaval from the past few years; we'll have to see if it continues in the longer term.

4angmoh
Imo Japan is one of the more illuminating examples on this topic: * Japan had a TFR of 5 in the 1930s. It's been only 3 generations since Japan's TFR began to fall, and France took 5 to stablise around the current level (1830s-1980s). I agree that the trend since 2005 is too short term to be sure, but it's interesting to note! The above modelling suggests that a faster fertility transition should result in a faster bounceback - the lower the TFR the more adaptive high-TFR genes + cultures will be relatively. * The fertility transition hit East Asia harder and faster than it did Europe. There's merit to the theory that it's because Europe had a slower transition to today's mainstream fertility-surpressing universal culture (technological advancement, enlightenment values. women's lib etc), since much of these cultural changes were developed in the West (consider the analogy to megafauna in Africa).   It's extremely difficult to quantify this sort of thing but it does support a model where both genes and culture are load-bearing inputs to TFR. In countries where culture propped up fertility one way or another there could be said to be a cultural fertility overhang, and when these forces were removed TFR naturally cratered in the short term.  Where countries had less cultural overhang, or a slower transition from high-TFR culture to low-TFR culture, the transition was less dramatic because there was time for cultural counter-developments or genetic selection to act. The example of Sth Korea (TFR >5 until the 60s) supports some of these theories. The timing is especially interesting - the 60s were a major leap forward in progressive cultural hegemony, and Sth Korea (an extremely poor society prior) copped that right in the face after the Korean War.  The idea is that the speed of TFR-decline is related to the severity of cultural change - makes sense to me.    An optimistic Sth Korean pro-natalist could interpret this current ultra-low TFR period as evidence of

When it comes to reducing prices paid, if you look at the UK for example, they have politicians who care about the NHI budget being manageable. If drugs don't provide enough benefits for the price they cost they don't approve them, so there's pressure to name reasonable prices.

Sure, but that doesn't address why you think researchers in these countries would be so affected by A... (read more)

Whether or not you use the word plagiarism, it's an ethical violation where people are paid money to do something in secret to further the interest of pharma companies.  What's what conspiring in private to mislead the public is about. The ghostwriting case is one that's well-documented. It's evidence that a lot of conspiracy exists in the field.  Your argument is basically "if they have power to do X, why don't they also have power to do Y". The only way to address that is to get into the details of how the power works. That means making new points.

It's interesting that you assume I'm talking about poorer countries. What about developed Asia? They have a strong medical research corp, and yet they are not home to companies that made covid-19 medication. Even in Europe, many countries are not host to relevant companies. You do realise that drug prices are much lower in the rest of the developed world compared to the US, right? I am not talking about 'poorer countries', I am talking about most of the developed world outside of the US, where there are more tightly regulated healthcare sectors, and where ... (read more)

Yes, the fact that there's a lot of conspiracy going on in Big Pharma is not an unique insight. That's just business as usual for Big Pharma in a way that should be obvious to any observer that pays attention. Ghost authorship isn't just putting a name on a paper to which you little contributed but also about the real authors not appearing on the paper. Ghostwriters are people who wrote something and don't appear on the author list.  If a student goes to upwork, lets someone write him an essay, does a few minor changes, and then turns it in under their own name while leaving out the real author of the paper that's seen as plagiarism by every academic department out there.

Your model of medical research could be true, if only countries with extensive investments in pharmaceuticals do clinical trials, all funding is controlled by "Big Pharma", and scientists are highly corruptible. Even then, it only takes one maverick research hospital to show the existence of a strong effect, if there is one. Thus, at best, you can argue that there's a weak effect which may or may not be beneficial compared to side-effects.

I don't think your view seems correct anyway. Many clinical trials, including those that found no significant effect, c... (read more)

In the Ivermectin case, you have a bunch of hospitals doing that. Enough that you could publish scientific meta-reviews in respected journals that came out in favor of Ivermectin. At the same time, you had the establishment organizations talk about how Ivermectin certainly can't work. That was the reason to look closer. At the time I thought, well here are those published meta-reviews and then there are the institutions that say that Ivermectin doesn't work, that's odd and I started a LessWrong thread to look together at the different papers. Prices are relatively legible to political stakeholders. It's easy for politicians to push in the direction of lower drug prices because they want to balance healthcare budgets. Poorer countries can say something along the lines of "Either you give us the drugs at a price that our citizens can afford, or we allow our own companies to produce the drugs in violation of your patent". Big Pharma companies are okay with making their profits mostly in rich countries and selling drugs in lower prices to poorer companies in exchange for their patents not being violated.  Directly, after COVID-19 emerged it would have been possible for governments to fund studies to investigate all generics that are candidates for possible treatments. To me that was surprising. While there are multiple different things that went wrong in the COVID response, it caused me to update that the existing institutions are more flawed than I previously assumed.  There's tons of evidence. Take https://www.theguardian.com/business/2012/jul/03/glaxosmithkline-fined-bribing-doctors-pharmaceuticals it's about a Big Pharma company having to pay $3bn in fines because they conspired with doctors by bribing them to encourage the prescription of unsuitable antidepressants to children. I think you need plenty of imagination to have a world where companies regularly have to pay billions in fines because they illegally bribed people and those bribes also had no effect.

That I have no personal experience with (yet), I haven't switched because of a planned move. That said, I've never heard anything negative about induction woks except for the price. I think they just work.

As someone who has been forced to use flat bottom pans due to the prevalence of electric coils in rental places in the US, I can say that most stir fries do benefit from a wok, and stir-fries are the bread-and-butter of homestyle cooking in many east and southeast asian cuisines.

It's not a make-it-or-break-it situation. The closer you get, the better; a carbon steel pan is often halfway there. A key issue in my experience is that woks allow for oil to pool even with very little oil, and stir-frying is often a hybrid sautee/shallow-fry. If you wanted to do ... (read more)

Ok. Thanks for letting me know about the "pooling" effect. How well do induction woks work compared to using a flame?
qjh00

Calling woks 'exotic forms of cooking' when they're (likely, given the Asian American pop.) the primary daily cooking vessel for millions of Americans, and probably a good fraction of the world population, is really a good reflection of how white-urban-American LW is.

For the record, I think everyone should switch to induction woks. Methane leaks are pretty bad for the climate. I certainly am switching to an induction wok. Still, weird to dismiss the main cooking tool of a huge groups of people as 'exotic'.

1[anonymous]
Well there is also the question of which wok recipes specifically need that shape of pan and cannot be adapted to use flat cookware. That subset of recipes that actually require a rounded pan would be the "edge case". I don't know enough about wok cooking to know if that is all of them or some of them. Or if the reason for the rounded pan is to transfer heat from a flame faster and with less fuel, which is irrelevant if you have induction.

But the detailed climate models are all basically garbage and don't add any good information beyond the naive model described above.

That's a strange conclusion to draw. The simple climate models basically has a "radiative forcing term"; that was well estimated even in the first IPCC reports in the late 80s. The problem is that "well-estimated" means to ~50%, if I remember correctly. More complex models are primarily concerned with the problem of figuring out the second decimal place of the radiative forcing and whether it has any temperature dependence or ... (read more)

One problem with trusting the experts is that there doesn't seem to really be experts at the question of how the knowledge gained in clinical trials translates into predicting treatment outcomes for patients. 

I mean, kinda? But at the same time, translation of clinical trials into patient outcomes is something that the medical community actively studies and thinks about from time to time, so it's really not like people are standing still on this.

Someone inside a field is generally able to see a larger breadth of evidence but at the same time, they have incentives not to bite the hand that feeds them. Big Pharma spends a lot of money to shape the system in a way where they can earn a lot of money by having patent-protected drugs that went through every expensive clinical trials being seen as the gold standard. Misconceptions about the nature of blinding don't exist because the involved researchers are stupid. Researchers that do well in STEM academia tend to be very intelligent. They exist because there are incentive pressures to keep those misconceptions alive.  When thinking about whether to look more at Ivermectin the question isn't "Do I as an outsider know more?" but "Are the billions that big pharma spends to bias research toward finding that patent pending drugs are better than generics strong enough to affect the expert judgments on Ivermectin".

But, while this might not be an indication of an error, it sure is a reason to worry. Because if each new alignment researcher pursues some new pathway, and can be sped up a little but not a ton by research-partners and operational support, then no matter how many new alignment visionaries we find, we aren't much decreasing the amount of time it takes to find a solution.

 

I'm not really convinced by this! I think a way to model this would be to imagine the "key" researchers as directed MCMC agents exploring the possible solution space. Maybe something ... (read more)

You might want to look into Berkeley Earth and Richard Muller (the founder). They have a sceptics' guide to climate change: https://berkeleyearth.org/wp-content/uploads/2022/12/skeptics-guide-to-climate-change.pdf

For context, Richard is a physicist who wasn't convinced by the climate change narrative, but actually put his money where his mouth is and decided to take on the work needed to prove his suspicions right. However, his work actually ended up convincing himself instead, as his worries about the statistical procedures and data selection actually end... (read more)

The linked PDF was not terribly detailed, but it more-or-less confirmed what I've long thought about climate change. Specifically: the mechanism by which atmospheric CO2 raises temperatures is well-understood and not really up for debate, as is the fact that human activity has contributed an enormous amount to atmospheric CO2. But the detailed climate models are all basically garbage and don't add any good information beyond the naive model described above. ETA: actually, I found that this is exactly what the Berkeley Earth study found: I feel doubly vindicated, both in my belief that complex climate models don't do much, but also that you don't need them to accurately describe the data from the recent past and to make broad predictions.

I think the Ivermectin debacle actually is a good demonstration for why people should just trust the 'experts' more often than not. Disclaimer of sorts: I am part of what people would call the scientific establishment too, though junior to Scott I think (hard to evaluate different fields and structures). However, I tend to apply this rule to myself as well. I do not think I have particular expertise outside of my fields, and I tend to trust scientific consensus as much as I can if it is not a matter I can have a professional opinion on.

As far as I can tell... (read more)

Yet I just don't know how to evaluate medical papers at all beyond the basics of sample size, because of all the field-specific jargon especially surrounding metastudies. Even for the large trial I linked, I figure it is good because experts in the field said so.

So it basically boils down to "there's a resolution to this debacle because experts said so". 

I haven't looked into Ivermectin evidence recently and thought like Zvi that engaging more with Alexandros isn't worth my time.
