Scott Alexander examines hypergamy in modern marriages, finding educational hypergamy has reversed while income hypergamy persists, with strong class homogamy for both genders. Longer summary

Scott Alexander examines the concept of hypergamy, particularly focusing on educational and income differences in heterosexual marriages. He finds that while educational hypergamy (women marrying more educated men) has reversed due to women's increasing educational attainment, income hypergamy (women marrying higher-earning men) persists. The post explores various studies on class, income, and educational matching in marriages, discusses the role of physical attractiveness, and touches on hypergamy in same-sex relationships. Scott concludes that class homogamy is strong for both genders, with looks playing a smaller role than often assumed in mate selection. Shorter summary

Scott Alexander critically examines studies on preschool effects, finding mixed and inconsistent evidence for long-term benefits. Longer summary

Scott Alexander reviews multiple studies on the long-term effects of preschool programs like Head Start. While early studies showed fade-out of test score gains, some found lasting benefits in adult outcomes. However, Scott finds inconsistencies between studies in which subgroups benefit and on which outcomes. He also notes concerns about potential p-hacking and researcher degrees of freedom. Ultimately, Scott concludes that the evidence is mixed - it permits believing preschool has small positive effects, but does not force that conclusion. He estimates 60% odds preschool helps in ways suggested by the studies, 40% odds it's useless. Shorter summary

Scott Alexander examines evidence for technological unemployment, finding little current impact but signs of 'technological underemployment' pushing workers to lower-skill jobs. Longer summary

Scott Alexander examines the arguments for and against technological unemployment, analyzing labor force participation rates, manufacturing job losses, and economic data to determine if automation is currently causing significant job displacement. He concludes that while there's little evidence of technological unemployment happening right now, there are signs of 'technological underemployment' where automation is pushing workers from middle-skill to lower-skill jobs. The long-term impacts remain uncertain, with economists divided on whether this is a temporary adjustment or a new normal. Shorter summary
