Staying uninformed before an election can be the economically rational choice
Learning enough to cast a genuinely informed vote takes real effort, but a single vote almost never changes a national election's outcome. Anthony Downs argued that weighing those two facts, it's perfectly rational for a voter to stay deliberately uninformed, since the personal payoff from research is close to zero however the election turns out. The same logic explains why voters often know more about their favourite sports team's roster than their own government's policies.
