Scott Alexander attempts to replicate a study linking beef jerky consumption to manic episodes in bipolar disorder, finding no significant relationship in his analysis of SSC survey data. Longer summary

Scott Alexander attempts to replicate a study that claimed beef jerky consumption could trigger manic episodes in bipolar disorder. He uses data from the 2019 Slate Star Codex survey to compare beef jerky consumption between people with and without a history of bipolar mania hospitalization. Contrary to the original study, Scott's analysis finds no significant relationship between beef jerky consumption and manic episodes. He discusses the limitations of his data, such as relying on self-reporting and having a smaller sample size of manic patients, but also notes some strengths like a more detailed measure of beef jerky consumption. Scott concludes by urging further research on this topic, highlighting the importance of replication in scientific studies. Shorter summary
