Scott Alexander writes two satirical sequels to GATTACA, critiquing discrimination based on epigenetics and educational background. Longer summary

This post is a satirical continuation of the movie GATTACA, imagining two sequels that critique different forms of discrimination. In 'GATTACA II: EPI-GATTACA', the focus is on epigenetics, where people are judged based on their ancestors' life experiences. In 'GATTACA III: EDU-GATTACA', the discrimination is based on which college one attended. Both stories follow a similar structure to the original GATTACA, with the protagonist Vincent trying to overcome societal barriers through deception. The stories end with Vincent's brother Anton helping him and Vincent realizing that he wants to change the discriminatory system, not just escape it. Shorter summary

Scott Alexander explores how people can have vastly different experiences of the world and others, even in similar circumstances, due to social bubbles, varying interpretations of social cues, and unconscious influences. Longer summary

Scott Alexander discusses how people can have vastly different experiences of the world and other people, even when in similar circumstances. He starts by recounting his experience as a psychiatrist, where his patients behaved differently from those of his colleagues, possibly due to his unconscious influence. He then explores the concept of paranoia and its opposite in Williams Syndrome, suggesting that people naturally vary in their tendency to interpret ambiguous situations positively or negatively. The post then delves into the concept of social bubbles, noting how the author's social circle differs dramatically from the general population in various ways. Finally, he ties these ideas together, proposing that people's different experiences of the world - whether they find others to be kind or cruel, discriminatory or accepting - may be due to a combination of self-selection into different social bubbles, varying tendencies in interpreting social cues, and unconscious influences on others' behavior.

Scott presents evidence for the reality and high economic costs of racial and gender discrimination, arguing that fighting prejudice is important and potentially effective. Longer summary

This post argues against Reactionary politics by defending the importance of fighting racism and sexism. It presents evidence from controlled experiments showing significant discrimination against minorities in job hiring, housing, and other areas. The post then estimates the economic costs of discrimination in the US to be at least $438 billion per year, comparable to the costs of major diseases. It concludes that even small successes in reducing racism and sexism could have large economic benefits, and that while many social justice efforts may be ineffective, there is potential for evidence-based approaches to make meaningful progress.
