Scott Alexander argues that while IQ is valuable for research, it's not reliable for predicting individual success and shouldn't be a major personal concern. Longer summary

Scott Alexander addresses the issue of people becoming overly concerned about their personal IQ scores. He explains that while IQ is a valuable research tool for understanding populations, it's not as useful or reliable for predicting individual outcomes. He points out that IQ tests often give inaccurate results for individuals, and even accurate IQ scores don't determine a person's potential for success. Alexander uses analogies like family wealth to illustrate how statistical correlations don't necessarily apply to individuals. He emphasizes that many factors beyond IQ contribute to success in various fields. The post aims to reassure readers who may be worried about their own IQ scores, while still maintaining the importance of IQ research for understanding broader societal trends. Shorter summary
