Scott Alexander examines political tribalism in America, arguing that people often claim tolerance while harboring strong prejudices against their outgroups. Longer summary

Scott Alexander explores the concept of outgroups and ingroups, arguing that people often claim to be tolerant of all groups except their perceived outgroup. He suggests that in modern American society, political tribes (Red and Blue) have become more significant than traditional demographic divisions. The essay analyzes how these tribes interact, criticize each other, and sometimes engage in self-criticism that may actually be veiled attacks on the opposing tribe. Alexander ultimately reflects on his own biases and the difficulty of genuine self-criticism and tolerance. Shorter summary
