The history of weight-lifting is bizarre. Babe Ruth became the most famous player in the history of baseball by lifting weights and no one copied him. He had the freedom to lift because he was a pitcher and no one cared about anything else he did (also the freedom to go for home runs at the expense of hits). And he had the time to lift because he was a star pitcher who didn't have to get a job in the off-season.

The San Diego Chargers won the 1963 championship openly using steroids. Afterwards they got quieter about the steroids, but not about the weightlifting. This should have disproved the idea that being muscle-bound slows you down. And yet it seems to have taken decades to get to other sports.

Sure, UIUC is somewhat elite and VC funding has always been elitist. But it's definitely not as elite as Stanford and if its relative share has fallen, that's a measure of increasing elitism.

A simple hypothesis that you seem to allude to is that UIUC had a much larger proportion of American CS students back then. NCSA told them that the internet existed. Now everyone knows that the internet exists and lots of people major in CS. So it might be a special case and its numbers could be going down even while general non-elite pool is going up. People funding based on prototypes is opposite to elitism.

That was clearly your main point and I agree with it.

Hey! I made a comment on that post. Five years ago, I used to know more about this topic.

According to that comment, the key parameter ("feedback") is more precisely estimated using ice age data than using global models. If this is correct, it seems like an important point and a strike against models. We should be trying to come up with other methods, rather than throwing more money into models. But even if it isn't true, Palmer agreed that the models fail to even conclude that the feedback is positive, ie, larger than the pure CO2 effect calculated by Arrhenius. (The main problem with the ice age data is that it is coarse-grained, so we only learn 1000 year long-term feedback, whereas we're more interested in 10 year or 100 year short term feedback. But usually people don't even acknowledge that these might be different. The failure to talk about these fundamental things really worries me.)

I thought the interview was awful.

Is there any point to climate modeling? I've heard grad students speak and they obviously don't know what the point is, but maybe they're just cogs in the machine. Is there adult supervision? This guy failed to convince me. Maybe he didn't try, but then what was the point of the interview? What were you trying to elicit? Your comment about how you need to combine modeling with theory was a push in the right direction, but it was too little, too late.

He said that the most important thing is whether clouds get lower or higher. That's great! Is modeling relevant to this? Is it certain that they'll get higher in some places and lower in other places, and so you have to model actual geography to get the answer? That would actually justify modeling as necessary to address the most important bottleneck. But I just made that up, flailing around to come up with any justification at all. Maybe there's some other justification, in which case it's not something he even mentioned. It sure doesn't look to me like most modeling is aimed at this, or any other narrow goal chosen for its importance. But modeling doesn't work, it's just too big. If this were the true goal, then most modeling should be aimed at simplifying this question, isolating variance from model error from discretization error. Are there functions that can summarize geography for the specific, narrow purpose?

Hoffman excerpt in NYT:

Erdös first did mathematics at the age of three, but for the last twenty-five years of his life, since the death of his mother, he put in nineteen-hour days, keeping himself fortified with 10 to 20 milligrams of Benzedrine or Ritalin, strong espresso, and caffeine tablets.
At five foot six, 130 pounds, Erdos had the wizened, cadaverous look of a drug addict, but friends insist he was frail and gaunt long before he started taking amphetamines.

Schechter's biography (google books) is more detailed:

After Anyuka’s death Turan counseled Erdős, “A strong fortress is our mathematics.” Erdős began to work up to nineteen hours a day on mathematics. Strong coffee was inadequate fuel to run such a prodigious theorem-proving machine. For many years Erdős had occasionally taken amphetamines to help him work. Hajnal recalls that as early as 1957 Erdős had had access to Benzedrine. “I took some of those pills,” Hajnal says. “When I took it I could work eighteen hours in a row.” But unlike Erdős, Hajnal did not have a steady supply. “He was very disciplined with it,” Hajnal said, and took it only in relatively small doses on days he wanted to work particularly hard. With his mother gone, Erdős wanted to work hard all the time and began to take amphetamines, washed down with strong coffee, every day.

So he did have access to them before his mother's death, back to when he was a spry 44. It is difficult to prove the negative that he did not have access to them before then. But they agree that he did not regularly use them, nor do the publicly visible behavior of working 19 hour days, before 1971. The famous bet is from 1979. How common was “occasionally”? Maybe he used them once a week and that was the heart of his productivity, but even so the description of his life is anachronistic (and maybe more rarely).

Which hold do you think he used? I think you are combining sources that disagree about which hold he used and thus deducing falsehoods. The court made no ruling on facts like that, because its job is to blame individuals, not to produce coherent knowledge.

2022-03-31 on an1lam-github-io

Erdos did not take amphetamine "throughout his life," but only started around age 60 when his mother died (see, eg, Hoffman's biography), long after his stature as a mathematician was established. I'd guess the amphetamine was just not relevant, but it's possible that stories of his habits in different parts of his life got mixed around.

Are you just arguing for a name change? Why would that have any effect? I speculate:

Perhaps it would narrow the focus to network effects? That sounds good, but I think everyone's focused on network effects already.

There seems to be a difference in that utility regulation is all-or-nothing, while antitrust is a often a bolt from the blue, with no follow-up to establish standards. But the "all" of utility regulation is often so micro-managed, nationalization might be better. There seems to be an implication in the name that legislatures would choose companies or fields to declare utilities and set up specific bureaucracies for regulating them, rather than empowering bureaucracies to find monopolies.


The most celebrated antitrust action, the break up of Ma Bell, was, in fact, the breakup of a regulated utility, which hadn't been allowed to set its own prices since it was it was granted a monopoly in 1918, and wasn't allowed to sell anything else (eg, transistors) since 1956. The government couldn't just end utility regulation, but had to pretend the monopoly had another cause.

Oil does not have any obvious network effect, but has historically been entangled with railroads: Standard Oil was vertically integrated with railroads; the Texas Railroad Commission set oil prices for decades.

But, as you say in your linked previous post, while it is clearly the bad times that precede the equality, there are serious missing mechanistic details that should prevent you from calling this story causal.

2022-02-02 on overcoming-bias

Does it mean anything about what I "want"? I shouldn't ask a genie to make a random pull from some natural distribution conditional on inequality falling, but I don't have a genie. My actions are based on causal models of how to achieve what I want, how to engineer outcomes that may be unlikely under the old distribution. It would be useful to know about the unforeseen consequences of my plan, but that's the opposite of the common causes of my goals. A communist revolutionary is not going to accidentally cause a war. He has chosen war, apparently having weighed the costs.

A plague is an exogenous shock. I don't wish for a plague. But if a plague comes, what should I do? The Black Plague did not have uniform effects. It increased equality in Western Europe, but inequality in Eastern Europe. It seems to have made class conflict salient, causing a reset of the system, an opportunity for people to change the system. It looks like this was a fulcrum of history, a place where large change was possible. But it's not clear what made the difference. Both places tightened their serfdom laws similarly, but the western peasants managed to just ignore them.

If there is a tradeoff between truth and other values, it should be easy to be more truthful than other people. Two of your three human examples of conformity traps are about such tradeoffs. The third, about journalist topics, is more murky.

It may be hard to be certain of your contrarian opinions on object-level issues, but when you argue for institutions for truth-seeking, it should be easy to certain of that argument. Maybe everyone claims to care about the truth (though I doubt it), but that's cheap talk. Requiring academics to use lots of math is selected for something, and it's not truth.

If it's what people value, then maybe it's not a trap. But even if it is, the local optimum found by selection can probably be improved by using the truth.

Dune Sequels:

In a decade earlier post, you asked two questions about the sequels: (1) are they any good and (2) was he planning them from the beginning, in particular in Appendix 3.

About 14 minutes in the 1985 talk, Herbert claims that he had the plan for the story encompassing the first three books already before he wrote the first one and talked to his agent about them, who convinced him that it was too much and to spread it out over multiple volumes. I’m not sure I believe him, but it seems pretty likely that by the time he wrote Appendix 3, which may have been a couple years after he wrote the body of the text, that it was at least a sequel hook.

There is more discussion of prescience in the sequels than the original book. One of the themes is conflict between prescient agents. I think the answer is to Appendix 3 is backwards causal influence from a powerful agent in the future, namely Paul's son. If you can see the future, agents in the future can shape your decisions. I think this answer is explicit in the later books, but I may have just gotten it from Gwern.

Some people are fans of the sequels, particularly the second and fourth volumes with their talk of prophecy and causal loops. I think Gwern is one such person. I thought he wrote short reviews of these books indicating that, but on goodreads he has only star ratings (5,5,2,4,3,3). Here’s a quote from him from a review of another book “Just like Dune Messiah thoroughly subverted and undermined the simplistic narratives presented for the reader to swallow in Dune…”

An exit pollster doesn't know who you are, but the conversation can be overheard by your neighbors, whereas the danger from a phone pollster is only from the pollster himself, really only from the possibility of being targeted by someone impersonating a pollster.


1 Related to Kaufmann's claim, the wired story says:

people lie not only before Election Day about whether they intend to vote, but also afterwards, about whether they actually did. (According to Schaffner, college-educated people are particularly bad offenders.)

2 When I cite the exit polls, I'm using NYT presentation of Edison. I think I got the link from Kaufmann, so he's probably using it, too, although he may have more direct access. I see other sources using unattributed exit polls, but I think they're all the same. It claims that it will eventually be tweaked to match the results, but seems to claim that it was not originally. Here is an archive of the first posting, from 2 in the morning after the election, which would seem to claim not to be tweaked, but doesn't look that different.

2020-11-18 on infoproc

It's not even clear to me that exit polls were accurate. They are consistent with the results, but they could contain canceling errors. In particular, they are massaged after seeing the results, so the fact that their totals are correct isn't much evidence.

Exit polls of mail-in voters are even done by phone. So exit pollsters have to understand the biases of phone versus in-person, which is itself correlated with vote.

A simple theory is that people lie about their plans, but don't lie about their past vote. But I don't believe it.

2020-11-18 on infoproc

Kaufman says that shy Trump voters lie to phone pollsters, but don't lie at the exit polls. I don't think that is plausible.

More plausible is that they don't pick up the phone, but they do talk to exit pollsters, although that's odd, too.

2020-11-15 on infoproc

The votes haven't been counted yet, but this looks to me like a 4 point miss, compared to a 1 point miss in 2016. That's worse than they promise, but it happens on a regular basis. Eyeballing Trafalgar's numbers, it looks like they were less accurate than mainstream pollsters in 2016, but more accurate than mainstream pollsters in 2020. They bragged about how they got the sign right in 2016, but that's irrelevant to predicting future success. And this year, they got the sign wrong, so few people were notice that they were the most accurate.

"Shy voters" is an ambiguous phrase. I don't think that anyone is lying about who they're going to vote for. But Trump voters do seem to be systematically unlikely to pick up the phone. In theory you asking people about their neighbors addresses that. This is related to the question of sampling corrections. I don't mean turnout, but the general problem of correcting for people who don't answer the phone, and finding a proxy for that to correct for. Again, this problem has been around forever. It's getting worse, but pollsters are getting better at dealing with it and I wouldn't predict which way it will go next time.

Sure, but how the most elite people train and compete seems like small potatoes, because there are so few elites. If colleges mimic elite colleges, that is a much bigger problem. Obviously they do, but I'm not sure how fast it attenuates as one travels down the status cline.

Also, that the consultants come out of their jobs with prestige seems to me worse than that they go into them with prestige. You can say that prestige should be about what people accomplish, but people claim that it already is about accomplishments; people claim that working at or just getting a consulting job is an accomplishment. It is this laundering of prestige that seems the big problem.

In most science fields you can't blind because people have research programs, not individual papers. Just read the bibliography and the most cited person is the the author of the paper or the advisor. A lot of this is maximizing publication count by disassembling papers into "minimal publishable units," but some of it is the reasonable consequence of research programs that existed a century ago.

This is much less true in the humanities, one way in which academic humanities is healthier than academic science. The unique way in which it is healthier?

Everything you say is false.

I was wrong though. 538 wasn't special in calling the vote within 1 point. Everyone did.

Here is Sam Wang's final pre-election post

The state poll-based Meta-Margin is Clinton +2.6%.
National polls give a median of Clinton +3.0 +/- 0.9% (10 polls with a start date of November 1st or later)

The day after the election, he was shocked that Clinton had only won by 1.2 points. That's the 2 point error I mentioned. I don't know whether he prefers the first prediction or the second prediction. But if I can't tell what he prediction is to 0.4 points, he
has no business claiming a 0.9 point margin of error.

Anyhow, Clinton did not win by only 1.2 points. He only said that because he doesn't know jack shit about counting votes. Ultimately, she won by 2.1 points, which does fall within his 0.9 point margin of error.

The problem with Wang is that he assumed independence of polling errors. Shy voters is one phenomenon that could cause dependence, but there are many others.

Sure, if there had been a shy Trump voter effect in 2016, that would be a reason to expect one in 2020. But there wasn't.

He says that pollsters should be judged on their records. I agree! You should look at what actually happened, rather than listen to advertising lies. If you don't bother to look at reality, you incentivize him to lie.

He says that the effect varied from 3 to 9 points (7 points?). Yes, it really was about 8 points in ND, but that's because no one bothered to poll there. It was also -2 points in HI, for the same reason. In the close, heavily polled states, the error was about 2 points. If he were to tell the truth about 2016, I might listen to his claims about 2020.

He does mention one way of directly measuring the effect: asking people how their neighbors would vote. But he says that everyone copied that, so the existing polls shouldn't have a shy voter effect! He claims that he has other ways of measuring it, but demands that I treat him as a black box. No, I don't trust liars.

OK, I was confused and phrased this badly. I should have distinguished between genic SNPs and the exome. Yes, you can't just run LASSO on the exome, both because of lack of samples and because of the large size of the exome.

What you could do (and could have done in the original paper) is take your SNPs, declare some of them to be genic and some not, restrict to the genic ones and run LASSO. This is strictly more informative than running LASSO and then restricting to the exomic SNPs. The latter is what you do in the beginning of the paper. In the end of the paper, you try to use the whole exome for imputation, which is slightly better. But it's better in an orthogonal direction, so it's no excuse for not doing the first thing.

2020-07-21 on infoproc

Yeah, I understood what you did and it was stupid. Shame on you.

You are making assumptions of independence and additivity that are probably true, but you could easily do a much better test of just running LASSO again.

The state of these SNPs cannot be determined from exome-sequencing data. This suggests that exome data alone will miss much of the heritability for these traits—i.e., existing PRS cannot be computed from exome data alone.

That's a pretty weak suggestion. It would be much better to rerun the analysis on just the exome data. This is just LASSO, right? easy to do.

Not really. The hard part of disagreement is just understanding what people mean. The vast majority of the time, I can't tell if there is a disagreement at all. (Really, I don't think most utterances denote anything.)

I believe my opinions because I believe my arguments. It's really important to distinguish people who disagree with me because they have fewer arguments from people who disagree because they have more. It's not generally useful to project them onto a 1-dimensional metric that claims that they agree with each other.

I think giving an argument and then doing a poll of whether people believe the argument (maybe true/unsound/invalid/other) would be more valuable than doing the poll just about the conclusion. I do think that the polls in your more recent futurism post were more useful, but I find it pretty hard to articulate why. Maybe because this one should be dominated by a single argument. If you can identify an argument, that should trump the poll.

I don't think that the professors in CST talk to each other about their research. The Committee grants PhDs, but I think that they are just as specialized as their advisors.

He defended expensive drug prices in America on the grounds that they go off patent and become cheap. But that's only true outside America!

First there is the issue of small molecule drugs vs biologics. For years people said that biologics were too hard for generics companies. There are three brands of fast insulin, not legally interchangeable. Their prices have gone up every year since they were introduced, with no effect of patent expiration. Outside America, there are generic brands, but inside America they are illegal. Monoclonal antibodies are even harder. A few generic manufacturers have gotten their drugs approved, but not as interchangeable. Finally, I think generic rituximab was approved a few months ago.

And even small molecule drugs have sporadic problems. We used to have cheap generic small molecule drugs, but that system is breaking down. I don't think generic modafinil brought the price down much. And then there have been lots of decades old drugs having shortages.

There is no reason to believe anything he said that is not in the book, but it is hard not to believe everything you hear and it is better not to be exposed to such sources.

Why do you list "art, entertainment, news" as not having scale? Distribution of information has the biggest returns of scale of anything, so a government might want to get in the business of distributing information and/or pick winners for the production of art, entertainment, and (non-local) news.

Except for the first item, all of these are the government accomplishing what the people want. Governments want taxes and patronage as well. I think that James C. Scott's idea of legibility fits in here somewhere, but maybe downstream of other abstractions.

Hollywood has moved in the direction of a larger share, but this is obscured by the talent having both an "agent" and a "manager." The agent is more of a negotiator and the manager is more of a mentor, but they both do networking.

None of this requires the government. Whoever wants to quarantine newly infected people could also quarantine people who are not newly infected. The only difference is that there is a larger supply of uninfected people than known-infected people, from which to draw volunteers.

Where do you get your definition of variolation?

Almost every source I looked at, including your wikipedia link, claim that the main value of variolation is in selecting mild strains of smallpox (ideally variola minor), not in controlling dose. Insufflation and especially inserting the virus into a cut sound to me like they would produce particularly high initial doses.

This seems exactly backwards to me. Squashing is slightly more difficult than flattening, but it takes much less time. After squashing there are years of contact tracing, which is difficult, but I think easier than anything else I have heard suggested.

If the government is not competent to quarantine sick people in hotels, then it is not competent to quarantine intentionally infected people. Maybe careful variolation is a good idea, but simply infecting people is risking just speeding up the epidemic. Complicated plans increase risks. If the government is too slow to move in the first place, it is too slow to implement complicated plans, too slow and incompetent to notice if the plan isn't working and readjust.

No, I don't feel lucky. I'm not optimistic that the government can implement the simplest plan, but I'm even more pessimistic about everything else.

Yes, the great value in infecting early is targeting health care workers, not this model.

Sure, the headline is true, but quarantining and everything that reduces R0 does increase infection date variance. What actions could you be criticizing? I guess delaying the patient zero just delays the epidemic. Are multiple initial patients better or worse?

Also, delaying infection date buys us time for innovation, like vaccines. Or just replacing broken kits.

What is the training that a theoretical physicist receives? How does it help? How do you know?

The null hypothesis about all of education is that it is just selecting for intelligence and a few other traits (which might be different from field to field). The more specialized the training, the less likely it is to transfer. I could believe that undergrad training is valuable, though how different is the valuable part in physics vs chemistry or math? But grad school? specifically theoretical physics?

There is a high-quality study of false identification, good enough to trump all the other evidence. Before DNA, 15% of rape convictions were the wrong man.

Has there been a million fold increase in programming and UI productivity over your lifetime? I think so. I think that the median code is written using tools a million times better.

In some sense there hasn't been much truly new since about [1973]. But there has been steady progress in shifting from slow, error-prone, low-level techniques to high-level techniques. The slowness of this progress is quite mysterious and there is still a lot of room to continue.

Everything you have heard about AT&T is a lie.

AT&T didn't set monopoly prices. The government set prices starting in 1917.
AT&T invented the transistor, but it never sold any. In 1954 the government not only confiscated the patent. Then anyone could sell transistors, anyone but AT&T, which the govern, it banned the company from selling transistors, or anything other than telecom.

An alternative hypothesis for early crazy hours is paying for inputs.

You say that the early period is unproductive, but why do you judge that? Junior lawyers are judged on billable hours, which is following the incentive of the law firm. Similarly management consultants.

If universities are judged on quantity of papers, then it makes sense to judge professors that way. But I think the main driver is that the job of a professor is to bring in grant money, ie, inputs, so that the university can skim off a percentage. The grant money needs an excuse to be spent on. The most lucrative professor is the one who can scale up spending. The easiest way to do this is to parallelize (eg, hire lots of grad students). Generating lots of papers is a proxy for being able to generate lot of paper ideas, which is a prerequisite for parallelizing, to justify lots of grant money.

I find it hard to explain investment banks and medicine this way, though.

What do you mean by "the purpose"? Whose purpose?

Maybe that's why some people like to hire people out of investment banks or biglaw, but why do investment banks and biglaw offer this signaling opportunity? For the first opportunity to hire the candidate? Maybe this makes sense for law, but don't investment bankers churn too much for this to make sense?

And medicine? Maybe if you want to hire the best doctors you have to filter them this way, but why are all doctors legally required to go through this hazing?

I'm not sure what you mean about academia. That academics are judged not just on quality, but also on quantity of papers?

Which is more mysterious, the behavior of the press before 2007 or the behavior after?

I'm not sure that the current attention is about Trump. Sure, that makes a difference, but I think that the new trials were enough to create attention on their own.

Did Corey say that this changed his opinion on the value of linguistics that he learned in the 80s? Did he never hear the 1985 quote "Every time I fire a linguist, the performance of our speech recognition system goes up" from Fred Jelinek?

(I'm not sure I agree with that jump, though. One of Chomsky's claims is simply that humans do have a sense of grammar. Deep learning teaches us to train end-to-end, but introspection of grammar suggests that's not what humans are doing.)

A simple explanation is that there are no capitalists, no return on capital, that the government has nationalized the means of production and the apparent returns on capital are labor income for stewarding the capital, set by the owner of capital with an eye on the incentives, but intentionally not reacting to this shock (or, indeed, adjusting against it).
