Jason Brennan’s Against Democracy makes a strong case that democratic majorities’ right to rule rests on shaky grounds so long as their ballot box decisions are heavily influenced by ignorance and bias.

Ironically, the biggest shortcoming of epistocracy may be that we lack the knowledge necessary to make it work well. © 2019 Informa UK Limited, trading as Taylor & Francis Group.
