The tools that we could use to get the "uninterested" to believe the truth work equally well for falsities, and are usually used to spread beliefs of convienience. If those tools were just sent down entirely, you'd be left with "right" and "random," and the random would always average out at the polls. Sadly, in our present world stupid is dangerous because machiavellians and martyrs alike are magnetizing it with arguments that are as wrong as they are emotionally convincing.
