Anatoly Karlin on "IQ in Time and Space", by Steve Sailer - The Unz Review
The highest score (107 on Anatoly’s Lynn-Vanhanen IQ-type scale where England is 100 and the standard deviation is 15) was in Japan, followed by Finland (105). Worst were Italy and Spain (95). That’s not a particularly huge difference compared to what’s seen on the PISA where much poorer non-OECD countries take the test.

Is legal marijuana more potent?
I believe that marijuana legalization has moved rather rapidly into being an overrated idea. To be clear, it is still an idea I favor. It seems to me wrong and immoral to put people in jail for ingesting substances into their body, or for aiding others in doing so, at least provided fraud is absent in the transaction. That said, IQ is so often what is truly scarce in society. And voluntary consumption decisions that lower IQ are not something we should be regarding with equanimity. Ideally I would like to see government discourage marijuana consumption by using the non-coercive tools at its disposal, for instance by making it harder for marijuana to have a prominent presence in the public sphere, or by discouraging more potent forms of the drug. How about higher taxes and less public availability for more potent forms of pot, just as in many states beer and stronger forms of alcohol are not always treated equally under the law?

Stumbling and Mumbling: Genes & the left
Freddie DeBoer has also had interesting things to say in this in the past. I think there's a real fear on the left, perhaps justified, that any acknowledgement of the heritability of IQ and/or its loose positive correlation with "outcomes" will lead to full Moldbug-style HBD talk. (Let's also acknowledge that talking about IQ in general can feel kind of masturbatory, a prelude to posting on LessWrong.)

But this gets it spot on, in that:
1) all other things being equal IQ (or some similar metric) does make a difference, but, crucially, all other things are not equal and we shouldn't ignore that;
2) a person's worth is not determined by their IQ

The trick is to acknowledge differences without ascribing value. Humans have been bad at this, historically.

Genes & IQ: The hits keep on coming, by Steve Sailer - The Unz Review
In our models, genetic variants in low LD with genotyped SNPs explain over half of the genetic variance in intelligence, education, and neuroticism. By capturing these additional genetic effects our models closely approximate the heritability estimates from twin studies for intelligence and education, but not for neuroticism and extraversion. We then replicated our finding using imputed molecular genetic data from unrelated individuals to show that ~50% of differences in intelligence, and ~40% of the differences in education, can be explained by genetic effects when a larger number of rare SNPs are included. From an evolutionary genetic perspective, a substantial contribution of rare genetic variants to individual differences in intelligence, and education is consistent with mutation-selection balance.

This may be the hardest brain teaser on the internet - Business Insider
“Three gods, A, B, and C, are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is completely random. You must determine the identities of A, B, and C by asking three yes-or-no questions, and each question must be posed to exactly one god. The gods understand English, but will answer all questions in their own language. In their unknown language, the words for “yes” and “no” are “da” and “ja,” in some order. You do not know which word means which.”

JUST YELL THE QUESTIONS UNTIL THEY ANSWER IN ENGLISH.

Are Sunk Costs Fallacies? - Gwern.net
But to what extent is the sunk cost fallacy a real fallacy?
Below, I argue the following:
1. sunk costs are probably issues in big organizations
- but maybe not ones that can be helped
2. sunk costs are not issues in animals
3. sunk costs appear to exist in children & adults
- but many apparent instances of the fallacy are better explained as part of a learning strategy
- and there’s little evidence sunk cost-like behavior leads to actual problems in individuals
4. much of what we call sunk cost looks like simple carelessness & thoughtlessness
