Scott Alexander challenges Richard Hanania's explanation for liberal dominance in institutions, attributing it instead to shifting coalition systems described by Thomas Piketty. Longer summary

Scott Alexander responds to Richard Hanania's article asking why everything is liberal despite roughly equal numbers of conservative and liberal voters. Alexander argues that the reason is not, as Hanania suggests, that liberals care more about politics, but rather due to shifting coalition systems as described by Thomas Piketty. Piketty's research shows a change from a 1950s system of elite vs. common parties to a current system where the left captures highly educated voters while the right captures less educated and some wealthy voters. This shift explains why institutions dominated by highly educated people lean liberal. Alexander discusses the implications of this shift, including potential instability in the system and the risk of institutional monocultures. He suggests potential solutions like decreasing the importance of college degrees in society and solving racism to shake up political coalitions. Shorter summary
