The Economist gives short shrift to rational choice explanations of voting:

More recent theorists have suggested that voting confers the “psychic benefits” (also known as a feeling of well-being) of performing a civic duty. But the argument that people do something because they like it is hardly an illuminating insight. Some academics reckon that voters are simply bad at calculating probabilities. Others produce reams of equations to back up complicated theories involving the social benefits of group membership.

Oh, this looks cool. Hands up who wants to use R to run interactive online experiments? (Puts both hands up.)
