Scott responds to comments about Lynn's IQ data, addressing how IQ testing might break down in under-educated populations and how this relates to the apparent disconnect between test scores and real-world capabilities. Longer summary

This post discusses comments on a previous article about Lynn's IQ data and African nations. Scott addresses several key points raised in the comments, including: how IQ tests might break down when testing under-educated populations, the relationship between abstract vs. practical intelligence, the confirmation of Lynn's general findings by other data sources, genetic diversity in Africa, and the characteristics of people with very low IQs. The discussion touches on how people with supposedly very low IQs can still function well in certain contexts, suggesting that IQ tests might not capture all aspects of intelligence, especially in populations with limited exposure to abstract reasoning and formal education.

Scott Alexander examines Richard Lynn's controversial national IQ estimates and argues they are actually consistent with environmental rather than genetic explanations of IQ differences, while explaining common misconceptions about what low IQ means. Longer summary

Scott Alexander discusses Richard Lynn's controversial national IQ estimates, which show very low IQs in some countries like Malawi. The post addresses two main objections: that such estimates are racist, and that they seem to contradict common sense observation. Scott argues that Lynn's findings are actually more consistent with anti-racist environmental explanations of IQ differences than with genetic ones, given the huge gaps in nutrition, healthcare and education. He then explains why normal people with low IQ appear more functional than those with similar IQs due to specific syndromes, since the latter have additional deficits beyond just low IQ. The post concludes that Lynn's data suggests room for optimism about the potential impact of developmental interventions. Shorter summary

Scott Alexander responds to comments on his capitalism vs charity post, clarifying his argument and addressing various counterpoints and suggested capitalist charities. Longer summary

Scott Alexander responds to comments on his previous post about capitalism and charity. He clarifies that he's discussing a specific near-mode situation of how to best use a limited amount of money for improving human welfare, not running a 'Moral Worth Tournament' between capitalism and charity. He addresses arguments for investing in capitalism over charity, discussing issues like compounding returns, marginal utility, and the eventual need for consumption. Scott also explores specific capitalist charities suggested by commenters, including charter cities and microfinance, noting the lack of strong empirical evidence for many of these interventions. He concludes by stating what kind of evidence would change his mind on this topic. Shorter summary

A critical review of 'Why Nations Fail' that examines the authors' academic work and methodology, while questioning the book's quality and practical implications. Longer summary

This review critiques 'Why Nations Fail' by Acemoglu and Robinson (AR), arguing that while the book itself is not very good, AR's academic papers present a more compelling case for their thesis that political institutions are the main determinant of economic growth. The reviewer explains AR's methodology using instrumental variables, discusses their evidence and criticisms, and ultimately concludes that even if AR are correct, their extremely long-run focus may not be very useful for practical policymaking or development efforts.

The review discusses how these ideas apply to modern development economics and Effective Altruism, suggesting the need for more qualitative research, emphasis on local context, and consideration of political implications in charitable work.

The post critically examines the impact of India's 1991 economic reforms, suggesting that the country's economic growth began earlier and that the causes are more complex than commonly believed. Longer summary

This post examines the economic reforms in India and their impact on poverty reduction and economic growth. The author challenges the widely held belief that the 1991 reforms were the primary cause of India's economic boom. By analyzing various studies and economic data, the post suggests that India's growth trajectory began earlier, possibly in the mid-1970s or early 1980s. The exact causes of this growth remain unclear, with various factors such as trade liberalization, public investment, and political attitudes towards business being potential contributors. The author also discusses the potential impact of socialist policies on developing countries and the importance of understanding these economic shifts for future policy-making and arguments against certain forms of socialism.
