I’m a big fan of compulsory voting. And I’m not the only one. Here’s Lisa Hill, from the University of Adelaide.

The most decisive means for arresting turnout decline and closing the socioeconomic voting gap is mandatory voting: in fact, it is the only mechanism that can push turnout anywhere near 95 percent. Places with mandatory voting also have less wealth inequality, lower levels of political corruption and higher levels of satisfaction with the way democracy is working than voluntary systems. Here in Australia, where we love freedom as much as anyone else, we have a mandatory voting regime that is well managed, corruption-free, easy to access, cheap to run and has an approval rating of more than 70 percent.

And when everyone votes, the outcome is much less dependent on turnout. Electoral swings to this or that party aren’t flukes of turnout; they’re big changes in the overall national mood.

But if everyone votes, including low-information voters, doesn’t that just mean that everyone votes stupidly? That’s the view of Jason Brennan, who argues that — dear heaven! — too many people vote already.

The median voter is incompetent at politics. The citizens who abstain are, on average, even more incompetent. If we force everyone to vote, the electorate will become even more irrational and misinformed. The result: not only will the worse candidate on the ballot get a better shot at winning, but the candidates who make it on the ballot in the first place will be worse.

He doesn’t want a democracy. He wants a cabal of elites to make wise choices for everyone.

I once talked to an angry young man who made exactly this argument. I told him that he was a clever person, but (quoting Douglas Adams) “you make the same mistake a lot of clever people do of thinking everyone else is stupid.” Of course, some people are stupid, but there’s no reason to think that all the stupidity or ill-informedness is always located in one or the other party. The stupidity is likely to be somewhat evenly distributed. Random bad answers will be randomly distributed, and they’ll cancel each other out. And along the way, you’ve gotten input from as many people as you can. If we have to err, let it be on the side of more participation.
