In the marketplace, we have an incentive to make informed decisions because we shoulder the cost and reap the benefits or drawbacks. In the voting booth, we get nothing good or bad for our individual decisions—because one vote almost never decides an election. Whatever results we have to live with are the same as they would have been if we hadn't bothered to vote.
If it doesn't pay to be informed, you might as well be ignorant. That reality accounts for much of the appeal of Donald Trump, whose campaign is built on absurd fantasies and false claims. He succeeds because his prescriptions are vivid enough to be appealing but vague enough to resist examination—not that voters examine them anyway. Steve Chapman explains more.
