Scott Alexander explains how to interpret 23andMe genetic data using SNPedia, listing various SNPs and their alleged effects while emphasizing the unreliability of such interpretations. Longer summary

Scott Alexander humorously explores how to use 23andMe genetic testing data 'irresponsibly' by looking up various SNPs (Single Nucleotide Polymorphisms) and their purported effects. He provides instructions on how to access raw genetic data from 23andMe and interpret it using SNPedia. The post then lists several interesting SNPs associated with traits like violence, empathy, anxiety, divorce risk, and longevity. Scott repeatedly emphasizes that these associations are often unreliable, exaggerated, or misinterpreted, and should be taken as entertainment rather than medical advice. Shorter summary

Scott Alexander drafts a letter to the FDA arguing against their decision to halt 23andMe's genetic testing services, highlighting the benefits and addressing the FDA's concerns. Longer summary

Scott Alexander writes a letter to the FDA expressing concern about their decision to halt 23andMe's genetic testing services. He argues that personal genomics services like 23andMe provide valuable and affordable genetic information to patients and doctors, raise awareness about genetics, and contribute to genetic research. Scott counters the FDA's concerns about false positives, test validation, and patient self-management, suggesting that these issues are either manageable or apply to many other medical tests and information sources. He urges the FDA to work with 23andMe to ensure their service returns to the market quickly. Shorter summary
