Learning aversion and voting rules in collective decision making

Author

Listed:
  • Louis, Philippos

Abstract

In collective decisions with uncertainty some voters may oppose the arrival of new information. This note formalizes a justification for supermajority as a voting rule in such environments. This is optimal when arrival of information is responsive to voters’ learning aversion, and conservative minorities have some power to block information.
