What makes democracy work so well? Ignorance. The majority of voters don’t know anything about the issues and of course have no idea what candidates will do once in office. Ecologist Iain Couzin at Princeton figures this makes democracy work great. Jonah Lehrer writes for the Wall Street Journal:

Why are democracies so vibrant even when composed of uninformed citizens? According to a new study led by the ecologist Iain Couzin at Princeton, this collective ignorance is an essential feature of democratic governments, not a bug. His research suggests that voters with weak political preferences help to prevent clusters of extremists from dominating the political process. Their apathy keeps us safe.
