The author is Jordan Lasker (also known by internet handle Crémieux). Much of Lasker's work and commentary focuses on race and IQ, and he has promoted eugenics. On X and Substack, Lasker is known for compiling charts on what he calls the "Black-White IQ gap"

The way he investigates how many of the winners from Romania are "Jews" (because apparently you can tell that by looking at their name and picture or whatever) is also very sus.

I have Ashkenazi friends that also love to point out how many of the winners of international Olympiads are Jewish. Does that make them sus too?

If it's a point of cultural pride, no. If it's a detached observation of racial intellectual superiority, yes.

You just read a comment that drew a distinction between racial supremacist claims and other claims and your rebuttal was that both kinds of claims are racial supremacist claims. Not interesting.

> your rebuttal was that both kinds of claims are racial supremacist claims

I said nothing about anything being racial or not. Perhaps you found it not interesting because you didn't pay attention to it and instead read into it what you already expected the rebuttal to be.

Yeah I was wondering where that came from, I think his background clears it up a bit.

Are his arguments sound, though?

In the middle ages, theologians had sound arguments for how many angels could dance on the head of a pin.

Then their arguments must have stood the test of time, good for them! More likely, their arguments weren't ever sound at all.

Sound arguments from faulty premises are still sound arguments – but identifying whether premises are valid is hard.

My heuristic, "if a sound argument concludes that racism is true, there's something wrong with the premises", is pretty effective in telling me where to look, but doesn't eliminate the hard work of distinguishing truth from falsehood. That this heuristic has never failed doesn't actually prove that all racism is false: only that all racism is afaik unevidenced, and that many specific theories of racism are false. (It does, however, provide increasing evidence that racists believe racism for reasons other than empirical observation, allowing me to confidently discount the evidentiality of their claims.)

I have slightly less evidence, but still quite a lot, generalising this from racism specifically, to all bigotry, which does put me at odds with the academic consensus in certain areas where I'm not otherwise an expert. Those academic consensuses do seem to be moving towards my understanding, though, so it seems to me that this is a pretty neat trick for getting ahead of the curve. (I'm a little surprised that intersectional feminist theory isn't taught to social scientists in school: what I rediscovered by brute-force has been known to the philosophers for decades.)

Well, take racism out of it. Do a thought experiment.

Take a genetically identical starting population with identical culture, customs, etc. Split them onto two islands, island A and island B. Island A has temperate weather, plentiful food, resources, and no natural predators. Island B has natural disasters, brutal seasons, intermittent food shortages, etc.

Check back in on both populations (assuming they lived exclusively on islands A & B) in 1000 years from the identical starting point. Do you think there would be any differences between them?

Of course there would be differences between the populations. There would probably be genetically-linked psychological differences, too! But would B-islanders be more cooperative, because they needed to band together to survive? Would they be more competitive, because those who hoarded resources for themselves reproduced better? Would A-islanders be better at analytical philosophy, because ability to publish in analytical philosophy journals was sexually selected for? Would that have no impact, because analytical philosophy skill has no significant genetic correlate, or would they actually be worse at analytical philosophy because ability to publish in analytical philosophy journals is a poor proxy metric? Or would A-islanders decide that analytical philosophy nerds are undesirable mates, and select against such an ability? Would cultural factors on island B result in a better, safer society where a decade's worth of preserved food is kept at all times, and nobody has to venture out into storms, while the A-islanders become their own predators and destroy each others' food supplies until they suffer entirely-avoidable famines?

Would all these various effects cancel each other out, leaving no phenotypical variation except skin colour (due to the selective effects of melanoma and vitamin D deficiency), and no significant psychological differences except those caused by unselected genetic drift, which are utterly erased by the first generation of interbreeding? There is no way to tell, from the information you have provided. Your thought experiment reveals your (and my) own biases, nothing more. Thought experiments only work in mathematics and physics, not (except in extremely simple situations) evolutionary biology.

Agreed, there is no way to know the exact degree of differences between the two populations (although any geneticist would reject the notion of primarily unselected genetic drift in the example I described. I specifically outlined strong selective pressures in the environments). But at least we agree that they would not continue to be identical, and that the environmental pressure, over time, would also show up in genetic drift between the populations (there are surprisingly many blank-slaters who would disagree even with this premise).

We have tools in modern science to attempt to differentiate between different underlying components of genetic variation vs environmental variation (identical twin studies, adoption-at-birth studies, general population studies, longitudinal analyses, etc). In lieu of a 1000-year experiment (which we cannot recreate), we can make predictions. If factor X was primarily genetic, we would expect to observe A, B, C. If factor X was primarily environmental, we would expect to observe D, E, F. Then, we can basically incorporate various studies and results and do gradient descent, and observing which (means squared error) is smaller.

None of this is groundbreaking stuff, I know. But I have read arguments from both the primarily environmental camp and the primarily genetics camp, and one of them has to do a lot more mental gymnastics explain the differences between obvious predictions (under this paradigm) and the observed data in the real world.

> I specifically outlined strong selective pressures in the environments

No, you didn't, because humans behave quite differently to your average animal. The only strong selective pressure you described was climactic: everything else can be mitigated with straightforward tool use. (And heck, going "oh, our skin is getting sunburned, let's be nocturnal instead" might cause your A-islanders to develop paler skin.)

You seem to be confusing "observed data in the real world" and "things that seem obviously true". If you pit your "obviously true" against other people's "obviously true" in your own head, of course your own "obviously true" is going to be the victor.

I hear this argument a lot and I don't know what you think it demonstrates. Put two groups of people on separate islands for 1000 years. Check back up on them. They will be overwhelmingly phenotypically similar. It's not like one of the groups is going to become the X-Men. Really, these analogies mostly seem like a device for smuggling in the premise that innate intellectual ability is less like color vision and more like eye color. Maybe it is, but you have to make and ground that argument.

What is the color vision equivalent of a savant? Surely you don't believe that any person could (given infinite time & training from birth), match the intellectual performance of a savant on, say, multiplying 6 digit numbers in their head?

(I think a clear savant that has a untouchable ability in one small dimension of mathematics is a clearer example than, say, von Neumann - who was equally brilliant but across many domains and in a less obvious way)

> multiplying 6 digit numbers in their head?

This kind of thing is quite easy. Which mental delay-line caches you exploit depends on how your mind works, but multiplying 6-digit numbers in your head isn't a hard trick to learn, if you care.

There was a time when I cared about such parlour tricks, and I could pick them up quite quickly. I once spent a few days memorising the first 10 digits of pi. Once I'd figured that out, it was the effort of a few hours over the subsequent weeks to memorise to 36 digits. If I had cared, I could have learned twenty new digits a day, using the following scheme:

See how it's lyrical? Just learn the poem. Except… I quickly found I didn't care, and at that point my motivation vanished, and I lost the "savant" ability. (Sure, if I wanted to, I could easily bootstrap the requisite intrinsic motivation – and I suspect I could learn a hundred digits a day thereby – but I don't want to.)

Despite my generally-absent enthusiasm, I'm still capable of aceing IQ tests, scoring highly in measures of cognitive ability that I do not possess, etc, because I have a certain stubbornness towards the idea that these tests truly measure anything important, which means I approach them sideways with the objective of breaking the tests, which means I break the tests. If anything of value hinged on my ability to quickly multiply 6-digit numbers in my head, I expect I could pick it up in… six months?

I do not say these things to brag: rather, the opposite. I don't think I am particularly exceptional: I never learned a thousand digits of pi, would probably take an hour to multiply 6-digit numbers in my head…

I am able to solve problems I've never encountered with computer systems I've never used, after half a second of thought, while concentrating on other things – but from the inside that doesn't feel exceptional at all: it's just a few tricks, well-practised. People who have memorised millions of digits of pi likewise claim to use a few tricks – and while those particular tricks don't always work for everyone, I don't think these people are innately exceptional.

I understand the argument, but I think you're missing the nuance somewhat. There are a series of things that are learnable mental tricks; I have read Moonwalking with Einstein and am well aware about rhyme techniques, memory palace techniques, etc. I memorized ~250 digits of pi in the 6th grade, so I'm also aware of techniques for that. I wouldn't consider either of those a domain of savants.

(sidenote - I would be impressed with the people that could memorize millions of digits of Pi, given that the world record is either 70,000 digits or ~110,000 digits last time I checked (depends on the source), and it takes ~6 hours just to recite that many digits)

I'm talking specifically like things like Hypercalculia: https://en.wikipedia.org/wiki/Hypercalculia , which are documented feats that cannot be explained by "tricks". Usually people with savant syndrome also have co-occurring autism and other neurological conditions like synesthesia.

Here is a an ABC profile of one of these savants: https://abcnews.go.com/2020/autistic-savant-daniel-tammet-so...

I don't think you could learn a "trick" to compute 27^7 in a few seconds.

Funny you should give 27^7 as an example, because I actually did get good at powers of 2 and 3. 27^7 is 3^21 is 3×81^5, which is easy to calculate in your head if you're good at multiples and powers of 8: it's just binomial expansion with the next row after 1 4 6 4 1, i.e. 1 5 10 10 5 1. (I used to be able to directly recall 1 5 10 10 5 1 and 1 6 15 20 15 6 1, but this is literally the first time I'm doing non-trivial mental arithmetic in a decade.) Multiplying a power of 2 by 5 is the same as halving and multiplying by 10, which reduces the problem to a simple addition of digits of small powers of 2 (^0 = 1, ^2 = 4, ^6 = 64, ^9 = 512, ^11 = 2048, ^15 = 32768), then a multiplication by 3 – both of which are easy to perform in a streaming fashion, if you have a suitable delay line. (I use the auditory processing delay line ("echoic memory"), which would probably work better if I spoke a language like Mandarin, where all digits have the same syllable length – but I got by. Some find the mental abacus more reliable, but I have no training in this approach.)

I only memorised my powers of 2 up to 2^16, powers of 3 up to 3^5, and powers of 5 up to 5^5, because the part that made it fun was only memorising things I'd calculated myself, in my head, and this was only an occasional game. If my goal had been "develop the skill of quick arithmetic", I would've memorised the first 12 powers of every prime below 12, and my times tables up to 100×100 – but I resented times tables, so never really memorised them until I (briefly) got really into division.

There is certainly variation in innate intellectual capability! There just isn't strong evidence of groupwide variation. Groupwide variation is the point of the "island" story.

I'm not going to make a scientifict argument about innate intellectual ability - I don't consider myself qualified enough for that.

I can only speak to my own observations. I have taught a lot of people to juggle. Juggling is an interesting discipline because it's pretty distinct from any other activity that most people have participated in in their life. It also has lower risk of "contamination", since people are unlikely to lie if you ask them if they've juggled before. You can also run this experiment with young kids, etc - you will still see very different rates of skill acquisition. I would bet that any other environmental arguments also fall flat - there are no big pro-juggling or anti-juggling cultures out there.

When you get a group of people together and instruct them to juggle, people will pick it up at very different rates. If you have enough of a sample size of observations, you can see extreme variability - some pick it up after 10-15 minutes, others still can't juggle after a year of trying (believe me, I've seen both). I've also observed brothers, both professional jugglers from a young age and both having invested identical amounts of time and passion into the activity (again, have no incentive to lie), progress at very different rates with acquisition of the skill.

From observing hundreds of people learning to juggle, I strongly believe that there is an "innate aptitude for juggling" in every person. Even people without this innate aptitude can learn to juggle and get to a certain level at the skill, beyond which progress will be so slow as to represent a de-facto "ceiling" on their juggling skill.

If you were to make this same argument in intellectual domains (i.e. chess, as an objective example), the argument gets more muddied in that you could make valid arguments that environment has played a role in "predisposing" someone to more rapid skill acquisition. However, I like to think of skill acquisition as more of a y = mx + b equation (not that all skill aquisition is linear). Every person has a certain rate (slope) at which they can aquire a given skill, and a certain intercept (predisposition) towards the acquisition of that skill. This model also works since someone that acquires skill more slowly can expend more time and achieve the same level of competence, but their ultimate ceiling of skill aquisition is lower (since time is finite).

I can make similar arguments about other domains, having spent time with IMO medalists, IOI medalists and other "outliers" in the intellectual domains. The same examples I showed above still apply, but the data is a lot more messy because it's hard in those cases separate the environmental/cultural effects from the genetic effects. That's why I reach for the juggling example as a clearer argument for that.

I'm not claiming that there's no variation in innate ability, only that one island won't be innately better at juggling than the other (certainly one island will be better at juggling, because they will care about juggling more, pass down more juggling, push forward the juggling sciences, &c. But those won't be innate, biological differences).

In other words: if, 1000 years later, you somehow stole an infant from bad-juggling island and had them raised on good-juggling island, they'd likely behave as you'd expect a good-juggle-islander to behave, despite their provenance. (Stipulate that there aren't outwardly evident signs of which island you're from, like inherited skin tone or whatever, which would alter your interactions with your environment).

I think if we agree that there are individual differences in predisposition towards juggling aptitude, and that the predisposition is mediated genetically somehow, and if juggling (in this hypothetical) is biologically advantageous for survival/reproduction on one of the islands (really stretching the analogy here) - then I don’t see a way how my 1000 years experiment doesn’t produce actual, population level genetic drift in juggling predisposition between the population on island A and island B (unless we could somehow prove that juggling predisposition is not heritable)

This is the crux of the issue. You assume, in the absence of evidence, that juggling aptitude predisposition is mediated genetically, in such a way that it is variable among humans; and you place the burden of proof on "somehow prove[ing] that [it] is not heritable" (emphasis mine). But it's far easier to prove the positive (in a world where the positive is true) than prove the negative (in a world where the positive is false), so the appropriate perspective to adopt if you want to investigate via experiment is "try to prove it true, and if we honestly fail, that's an argument that it's false".

If you don't intend to run the experiment, then different considerations dominate: you should justify this bias. Maybe you're drawing an analogy to something similar, which you know to work this way? Bias isn't the same thing as wrong, after all: but unjustified bias often is.

The problem with all IQ and race correlations is that you can never actually remove the effects of prenatal and childhood nutrition, socioeconomic differences, quality of education etc. Indeed, if you stabilize them, the differences go away. And that's still saying nothing of the culture-neutrality of IQ tests themselves.

Stop defending racism and racists

I don't think pillefitz is asking if the author's racist arguments in general are sound. I think he was asking if the arguments in this particular article are sound.

Many racists are actually quite competent outside of when they are trying to argue for racism, and this particular article doesn't seem to be making a racist argument.

It does talk about the possibility of an over performing ethnic group, and suggests Jews as a candidate, but that's not inherently a racist argument. There are in fact ethnic groups in many countries that do over or under perform as a whole, but this is almost always due to cultural factors.

In particular ethnic groups where education and scholarship are a big part of their culture unsurprising tend to over perform in general society unless their culture also is big on minimizing interacting outside their group.

Jewish culture is such a culture and they have long been over represented in intellectual fields unless they are in a country that has high social or legal barriers to keep Jews out of those fields. Heck, this is probably why so many stupid conspiracy theories have them as the people secretly running the world.

It's similar with many Asian cultures nowadays. Just take a stroll through the campus of Caltech or MIT if you want to see that those groups over perform. At both those schools around 48% of undergraduates are Asian. That's way above the 7% of Asians in the general US population. Even if we take into account that Caltech has a disproportionate number of students from California (if you can get into a top STEM school and are from California, are you really want to go deal with Boston weather?) and California has a high Asian population (about 16%) the 48% at Caltech is way higher.

That said, I don't think the arguments in this article are really all that good. He is emphasizing the IMO since 2020 and talking about how 2022-2024 stand out. But when you look farther back instead of starting at 2020 then 2022-2024 are still good years, but not really remarkable years for Romania. Over the period it has been good it has had some major changes in their education system which I think limits what you can infer from recent IMO success. I've got another comment that goes into more detail: https://news.ycombinator.com/item?id=45071972

Not remotely; he operates in the phlogiston area of the science he makes claims in: old twin studies, Richard Lynn's overtly fraudulent numbers, &c. There is a vibrant field of research on these topics; he is not part of it. Search for his name alongside Turkheimer's on Twitter for some backstory.

Yeah, he post things like "there are no more excuses to be fat". Nasty dude. Romania's overall educational system is unimpressive, as he pointed out himself. Yet he suggested to replicate it in different countries to "get more out of the smartest ones".
