Scott Alexander partially retracts and corrects his previous findings on age gaps and birth order effects after errors were identified in his analysis. Longer summary

Scott Alexander partially retracts his previous findings on age gaps and birth order effects. He acknowledges that Bucky, a Less Wrong user, found errors in his analysis of SSC survey data. While the original conclusion about firstborn children being overrepresented in high-openness STEM types remains valid, the specific findings about age gaps were partially incorrect. Scott explains the errors, presents Bucky's corrected analysis, and discusses the implications. He emphasizes the importance of data transparency and encourages readers to double-check his work.

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

Scott Alexander analyzes birth order effects in SSC readers, finding strong effects for sibling age gaps of 1-7 years, with a significant drop-off after 7 years. Longer summary

Scott Alexander investigates birth order effects using data from the 2019 Slate Star Codex survey. He finds that firstborns are overrepresented among SSC readers, replicating previous findings. The study focuses on how age gaps between siblings affect this birth order effect. Results show strong effects for age gaps of 1-7 years, with a dramatic decrease for gaps larger than 7 years. Scott discusses possible explanations for these findings, including intra-family competition and parental investment hypotheses. He notes that the results don't seem consistent with some other proposed mechanisms like maternal antibodies or vitamin deficiencies. The post ends with a call for further replication and expansion of these results. Shorter summary

Scott analyzes a surprising age-related trend in responses to a parentheses riddle on the SSC survey, exploring possible explanations for why younger respondents were more likely to answer correctly. Longer summary

Scott Alexander discusses a parentheses riddle included in the SSC survey, which unexpectedly revealed a strong correlation between age and the likelihood of answering correctly. Younger respondents were more than twice as likely to choose the correct answer (B) compared to those in their 60s. Scott explores various hypotheses to explain this trend, including tech-savviness, cognitive decline, and survey-taking attitudes, but finds these explanations unsatisfactory. He speculates that age-related cognitive decline might affect parentheses-reading faculties specifically, independent of general intelligence. The post ends with an edit noting commenters' suggestion that younger people might have encountered the riddle before on social media. Shorter summary

Scott Alexander reports on weak correlations and inconclusive results from the latest SSC survey on optical illusions and visual perception. Longer summary

Scott Alexander discusses the results of the latest SSC survey, focusing on optical illusions and visual riddles. He admits to being unable to expand on or strengthen his previous findings from 'Why Are Transgender People Immune To Optical Illusions' and 'Can We Link Perception And Cognition?'. While he weakly replicated some previous results, the correlations were too low to be exciting. He found minimal internal structure in the results, with different versions of the same illusion showing low correlation. The post also briefly mentions some pre-registered investigations that yielded uninteresting or negative results, including studies on political conflict theory, autism and categorization responses, and ADHD and ambition. Shorter summary

Scott analyzes survey data to test the claim that rejection sensitivity is a key feature of ADHD, finding limited support and emphasizing caution in adopting such ideas without formal research. Longer summary

Scott Alexander investigates the claim that rejection-sensitive dysphoria is a key feature of ADHD using data from the Slate Star Codex survey. He finds that while people with ADHD do show slightly higher rejection sensitivity than those without psychiatric conditions, it's not as dramatic as some claim, and ADHD actually shows the lowest rejection sensitivity among the psychiatric conditions studied. The post critiques the lack of formal evidence for this claim, discusses potential Forer effects, and emphasizes the need for caution when adopting new ideas about psychiatric symptoms, especially those spread in patient communities without formal research backing.

Scott Alexander analyzes survey data showing lower sexual harassment rates in STEM fields compared to other industries, contradicting media narratives, while urging caution and calling for more research. Longer summary

Scott Alexander analyzes data from his blog's survey on sexual harassment rates across different fields. The survey found that STEM and traditionally male-dominated fields had lower rates of reported sexual harassment compared to more verbal/personal skills-oriented fields. This contradicts media narratives about tech having unusually high harassment rates. Scott notes the strong correlation between at-work and out-of-work harassment rates across fields, suggesting differences may be more related to the people in each field rather than workplace cultures. He urges caution in interpreting the results, acknowledges potential biases, and calls for more rigorous research on this topic given the lack of good comparative data across industries. Shorter summary

Scott Alexander analyzes SSC survey data to explore the conflict vs. mistake theory distinction in political disagreements, finding that Marxists and the alt-right tend more towards conflict theory than other groups. Longer summary

Scott Alexander analyzes data from the SSC survey to explore the distinction between conflict theory and mistake theory in political disagreements. The post presents various survey questions that tap into this distinction and shows correlations between responses. Results indicate that Marxists and the alt-right tend more towards conflict theory, while libertarians and liberals lean more towards mistake theory. The analysis also explores relationships between conflict theory tendencies and various demographic factors, finding some weak correlations with financial situation, self-perceived morality, and certain personality traits.

Scott Alexander analyzes SSC survey results on trust, finding correlations with education, location, and political views, but not with gender, race, or religiosity. Longer summary

Scott Alexander analyzes the results of the SSC survey question on trust, exploring how different factors correlate with people's tendency to find others trustworthy. He finds that trust levels don't significantly differ by gender, race, religiosity, or intelligence, but there are differences based on education level, location, and political views. Urban and liberal areas tend to be more trusting, as do more educated individuals. Conservatives are generally less trusting than liberals. Effective altruists and polyamorous Less Wrong readers from California are found to be the most trusting groups. The post also notes correlations with mental health conditions and drug use, and observes that people who chose 'Other' in any category were consistently less trusting. Shorter summary
