Scott Alexander examines why certain families produce multiple generations of high achievers, exploring genetic, environmental, and psychological factors. Longer summary

Scott Alexander explores the phenomenon of highly accomplished families, such as the Huxleys, Darwins, and Curies, who have produced multiple generations of notable scientists, artists, and leaders. He discusses potential explanations for this trend, including privilege, genetics, and unique family environments. The post delves into the role of assortative mating, large family sizes, and the correlation between different types of talents. It also touches on the concept of a 'Hero License' - the idea that coming from an accomplished family might instill the confidence to pursue ambitious goals. Shorter summary

Scott Alexander analyzes survey data to investigate whether assortative mating among highly analytical people increases autism risk in their children, finding no significant evidence for this hypothesis. Longer summary

Scott Alexander investigates whether assortative mating among highly analytical people in Silicon Valley increases the risk of autism in their children. He uses data from the 2020 Slate Star Codex survey, which included 8,043 respondents from highly analytical backgrounds. The study found that while the sample had higher rates of autism (4-8%) than the general population (2.5-5%), there was no significant increase in autism rates among children of couples where both partners were highly analytical. The autism rate for children in the sample was 3.7-5.2%, with only 0.6% having severe autism. Scott concludes that while the study has limitations, it provides evidence against strong versions of the assortative mating hypothesis for autism risk. Shorter summary
