Neo-Pentecostal gangs in Brazil, driving out other faiths at gunpoint. A mob of 100 lawyers attacking a hospital in Pakistan to revenge themselves on violent doctors there. Anti-vaxxers, neo-Nazis, and red-pillers. Sometimes it seems like the world has fragmented into a jagged kaleidoscope of countless mobs and subcultures, each more disconcerting than the last.

Much of this is selection bias: if it bleeds, it leads, in both mass media and social-media algorithms. But it does seem plausible that the Internet is contributing to this kaleidoscope, to this growth in worrisome fringe subcultures, in three separate ways: complexity, information, and connectivity.
