The post argues against the idea that the Griggs vs. Duke Power Co. case is responsible for credentialism in employment, presenting evidence that the issue is more complex and widespread. Longer summary

This post challenges the common belief that the Griggs vs. Duke Power Co. Supreme Court case is responsible for the rise of credentialism in employment. The author presents several arguments against this notion: 1) The Griggs decision applies equally to college degrees and IQ tests, yet degrees are still widely used. 2) Other countries without similar laws face similar credentialism issues. 3) It's legal and possible for employers to ask for SAT scores (which approximate IQ tests), but this practice hasn't caught on. 4) Fields with standardized tests (like medicine) still heavily rely on credentials. The author concludes that the roots of credentialism likely lie deeper than this single court decision. Shorter summary

The post explores a new model for understanding mental disorders as networks of interconnected symptoms rather than discrete diseases with underlying causes. Longer summary

This post discusses a new way of understanding mental disorders proposed by Nuijten, Deserno, Cramer, and Borsboom (NDCB). Instead of viewing psychiatric conditions as discrete diseases with underlying causes, they suggest viewing them as networks of interconnected symptoms. The author explains how this model can account for various aspects of mental illness that are difficult to explain with traditional models, such as comorbidity, the effects of life stressors, and the polygenic nature of mental illnesses. The post also considers some limitations of this approach, particularly in explaining conditions like bipolar disorder and the rapid effects of treatments like ketamine. Despite these issues, the author finds the network model compelling as a way to understand the complexity of psychiatric disorders. 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
