Scott Alexander reviews the results of the Impact Market Mini-Grants test run, discussing the top projects and lessons learned about this novel charitable funding method. Longer summary

Scott Alexander reports on the results of the Impact Market Mini-Grants, a novel way of running charitable grants where investors fund promising projects and grantmakers buy credit for successes.

Scott discusses the top five projects, including a rationality education program at the University of Maryland, a forecasting tournament, a tool for making Kelly-optimal bets, a paper on forecasting long-term impacts, and an ambitious impact assessment project in India. He reflects on the lessons learned from this experiment, noting both successes and challenges in implementing the impact market concept. Shorter summary

Scott Alexander argues for a universal right to self-determination, critiquing the current paradigm of determining which groups qualify as 'peoples'. Longer summary

Scott Alexander explores the concept of self-determination in international politics, focusing on the case of Ukraine and Russia.

The post discusses the complexities and potential problems with this approach, including the cases of Crimea and the American Confederacy. Scott concludes that while his position leads to some controversial conclusions, it's more consistent and ethically sound than basing self-determination on subjective cultural or historical criteria.

Scott Alexander examines the history of increasing competitiveness in college admissions, analyzing causes and questioning whether the focus on elite college admission is justified. Longer summary

Scott Alexander explores the history of college admissions and the increasing competitiveness in recent years. He traces the evolution from a time when top colleges admitted almost anyone qualified to the current highly competitive landscape. The post examines various factors contributing to this change, including increased applications per student, changing demographics, and shifts in evaluation criteria.

Scott Alexander tests the claim that mathematicians' preference for algebra or analysis predicts their corn-eating style, finding no significant correlation in a survey of over 2,600 respondents. Longer summary

Scott Alexander investigates a claim made by Ben Tilly that mathematicians' preference for algebra or analysis predicts how they eat corn (in rows or spirals). Scott included questions about math preference and corn-eating style in his 2019 Slate Star Codex reader survey. Analyzing 2,683 responses, including a subset of PhD mathematicians, he found no significant correlation between math preference and corn-eating style, contradicting Tilly's observation. Scott suggests the original claim might be due to the power of suggestion or selective memory. He also explores demographic factors influencing corn-eating styles, finding some cultural differences but no clear explanation for the variability. Shorter summary

Scott Alexander hypothesizes a link between transgender identity, optical illusions, and NMDA receptor function, based on survey data and existing research on schizophrenia and autism. Longer summary

Scott Alexander explores a potential link between transgender identity, optical illusions, and NMDA receptor function in the brain. He presents survey data suggesting that transgender individuals, like those with schizophrenia and autism, are less susceptible to certain optical illusions. He hypothesizes that this might be related to NMDA receptor hypofunction, which is also associated with dissociation, a common experience among transgender people. The post explores how estrogen, which enhances NMDA function, alleviates dissociation in trans women. Scott connects these findings to broader research on NMDA receptors in schizophrenia and autism, noting the higher prevalence of these conditions in transgender populations. The post concludes with several caveats and suggestions for future research to validate these speculative connections. Shorter summary
