He finds significant inconsistencies and methodological issues in the various studies, making it difficult to draw firm conclusions. The post highlights problems with data interpretation, study replication, and potential confounding factors. Scott emphasizes the unreliability of these early happiness studies, which predate improvements brought by the replication crisis in social science. He concludes that the research is not rigorous enough to make definitive statements about Amish happiness levels relative to other groups. Shorter summary

Scott Alexander refutes PZ Myers' race car analogy against genetic engineering for intelligence, showing that high IQ positively correlates with many beneficial traits. Longer summary

Scott Alexander critiques PZ Myers' argument against genetic engineering for intelligence, which uses a race car analogy to suggest optimizing for intelligence might trade off against other important traits. Scott shows that, contrary to this intuition, high IQ correlates positively with many desirable traits like longevity, height, and health. He explores possible explanations for this, including heterozygosity advantages, mutational load, and trade-offs with traits important in evolutionary history but less so now. Scott concludes that while caution is warranted, the race car argument is likely less of an impediment to genetic engineering than it might seem. Shorter summary
