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 Alexander explores how selection bias might create the stereotype of angry, vocal atheists, and speculates on how this concept might apply to other groups. Longer summary

This post discusses how selection bias may contribute to the stereotype of atheists as loud and angry. Scott argues that while religious people are visible in many contexts, atheists are typically only noticed when criticizing religion or advocating for atheist causes. This creates a false impression that atheists are obsessed with attacking religion. The post suggests that most atheists rarely discuss their lack of belief, but these individuals don't get attention as atheists. Scott then extends this concept to other groups, speculating that similar selection biases might contribute to stereotypes about Muslims, Christians in secular areas, and even ethnic groups.
