Scott Alexander discusses the online forum Longecity, where users organize group buys of experimental chemicals, seeing it as a risky but intriguing counterbalance to slow drug approval processes. Longer summary

Scott Alexander expresses admiration for Longecity, an online forum where users organize group buys of experimental chemicals for self-experimentation. While acknowledging the dangers and irresponsibility of such practices, he finds a certain appeal in how it counteracts potential suppression of wonder drugs by slow-moving institutions. The post discusses examples of ongoing group buys, including attempts to replicate anti-aging experiments in rats. Scott concludes by suggesting that while this behavior is risky, it serves as a safeguard against dystopian scenarios where beneficial drugs are suppressed, reflecting a balance between institutional stupidity and population insanity in Western civilization.
