Scott investigates unusually high suicide rates in Guyana, Greenland, and Siberian regions, exploring potential ethnic, cultural, and social factors contributing to these trends. Longer summary

This post explores unusually high suicide rates in different parts of the world, focusing on Guyana, Greenland, and remote Siberian regions. Scott examines potential causes for these high rates, including ethnic and cultural factors, alcohol consumption, social disruption, and abuse. For Guyana, he notes the high rate among Indo-Guyanese, speculating on possible cultural or historical reasons. In Greenland, he discusses the dramatic increase in suicide rates since the 1970s, linking it to forced modernization and a spike in alcohol consumption. For Siberian groups, he explores various theories including genetics and cultural traditions, but ultimately suggests that the combination of alcohol-naive hunter-gatherers, high alcohol consumption, and disruption of traditional ways of life may be the primary factors across these regions.

Scott Alexander challenges the popular interpretation of the Rat Park study, arguing that addiction is not solely caused by poor environments and emphasizing genetic factors in addiction susceptibility. Longer summary

Scott Alexander critiques the 'Rat Park' study and its popularized interpretation that drug addiction is primarily caused by poor social environments. He presents historical examples of addiction in seemingly happy or fortunate individuals, such as Ogedei Khan and Native Americans, to challenge this view. The post then discusses the genetic factors in addiction, citing twin studies and known genetic markers. Scott acknowledges that unhappiness likely contributes to drug use but argues that the relationship between environment and addiction is more complex than the Rat Park model suggests. He proposes a toy model where other sources of reward can help resist drug addiction, but maintains that biological interventions like deregulating suboxone and researching psychedelic therapy are more immediately effective for helping addicts.
