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.
