Scott Alexander replicates and analyzes data showing higher rates of long COVID among bisexuals, suggesting a significant psychosomatic component to the condition. Longer summary

Scott Alexander attempts to replicate a CDC finding that bisexuals were 50% more likely to report long COVID than heterosexuals. Using data from his own ACX survey, he finds that bisexual women were twice as likely, and bisexual men 50% more likely, to report long COVID compared to their heterosexual counterparts. He also notes correlations between long COVID and various mental illnesses. Scott suggests these results indicate that a substantial portion of long COVID cases may be psychosomatic, potentially classifying excess cases as a culture-bound mental illness. He proposes compassionate treatment for unavoidable cases alongside 'unawareness campaigns' to minimize avoidable psychosomatic ones. Shorter summary

Scott Alexander reviews evidence on face mask effectiveness against coronavirus, concluding they likely offer some protection despite CDC recommendations against general public use. Longer summary

This post examines the effectiveness of face masks in preventing coronavirus transmission. It reviews theoretical reasons, case-control studies, randomized trials, and laboratory studies on surgical masks and N95 respirators. The author concludes that while not perfect, surgical masks likely offer some protection against infection in high-risk situations. The post also discusses the CDC's recommendations against mask use for the general public, suggesting this may be due to high standards of proof in medical communication rather than intentional deception. The author ultimately recommends considering mask use in high-risk situations if supplies are not limited, while emphasizing that masks are not a substitute for avoiding such situations when possible.
