Nature has a review of Robert Plomin’s new book by some random lefty historian data-free reasoning type called Nathaniel Comfort (he follows the usual pattern of having a background in biology, as the usual suspects). Among the usual claims without any supporting references we find this one: Crude hereditarianism often re-emerges after major advances in […]

There’s a lot of evidence for left-wing dominance of academia. One study (Langbert 2018) looked at registered voters and finds quite unbelievable differences: In this article I offer new evidence about something readers of Academic Questions already know: The political registration of full-time, Ph.D.-holding professors in top-tier liberal arts colleges is overwhelmingly Democratic. Indeed, faculty […]

People commonly ascribe large effects to having this or that teacher, or this or that classmate. They usually cite some anecdotes from their personal lives for this, but large sample size, systematic data are strongly negative on the idea. This means that to the extent one can measure things, teachers are largely interchangeable in terms […]

The theory seems obvious: since stereotypes are just beliefs about groups, having more accurate stereotypes would be expected to be related to intelligence, just as having more accurate beliefs on most other topics relates to intelligence. The theoretical expectation of stereotype accuracy and intelligence is stronger because it’s a direct test of pattern recognition with […]

Given the recent discussion of sex differences in variation in traits, The Audacious Epigone has a quick post based on the GSS (you guessed it). He finds: The weight finding is probably related to female self-starvation for beauty purposes (anorexia) which creates a stronger left tail for women but not for men. The physical attractiveness […]

Since this topic comes up repeatedly and I have to find the same studies over and over, here’s a little review. Vertical cultural transfer (various other names: vertical cultural inheritance, cultural transmission) is the main effect proposed by various social scientists for the similarity of parents and kids. It differs from the shared environment concept. […]

Wilson, R. S. (1976). Concordance in physical growth for monozygotic and dizygotic twins. Annals of Human Biology, 3(1), 1-10. Heights and weights were analysed for 636 twins who had been repeatedly measured from birth to 4 years. MZ twins were less concordant for birth weight than DZ twins, principally as a result of a few […]

Camerer et al, Evaluating the replicability of social science experiments in Nature and Science between 2010 and 2015, Nature Human Behavior, 2018 Being able to replicate scientific findings is crucial for scientific progress. We replicate 21 systematically selected experimental studies in the social sciences published in Nature and Science between 2010 and 2015. The replications […]

Since people keep asking about my results on such tests, and because my position has been misrepresented (e.g. by Les Temps). There’s a lot of political tests online one can take, but some are more popular than others, and sensible. A popular choice is the libertarian-made, The World’s Smallest Political Quiz, a 10 item quiz […]
