When economists look at voting, they usually say that the benefit from voting is the probability that your vote will be the deciding vote in an election. Since no major political election in American history has been decided by one vote–or even by anything close to one vote–this means that the effective benefit of voting is basically zero.
And yet people vote. What’s more, we have an idea that people ought to vote, and that they probably should try to be moderately informed about it, too.
Jason Brennan is one philosopher who feels quite differently. His argument, in The Ethics of Voting, is that there’s no real civic duty to vote. If you’re uninformed, he argues, then your vote does more harm than good. And instead of spending the effort to become informed, why not spend the effort on some other socially beneficial activity? Start a business, found a charity, volunteer somewhere: but skip the voting.
Here’s the problem with that analysis, however. The term “more informed” is, by definition, relative. So if we say that only the most informed 50% of the electorate should vote (morally speaking, I’m not suggesting any kind of law or policy to disenfranchise ignorant people here), why stop there? Now instead of 200,000,000 voters you have 100,000,000 voters, but 50% of them are smarter than the other 50%, so shouldn’t we reduce the number again, to 50,000,000? The point is that there’s no good reason to ever stop this winnowing process until we end up with a world where only a handful of super-geniuses are voting and the rest of us are just sitting on the sidelines.
