Clearly there’s a tradeoff to be made here. In order to learn about the world, you need to let ideas in. But the more ideas you let in, the more bad ideas you let in. You can (and should) set up border controls, but you can’t achieve perfect truth-filtering any more than you can turn your house into a cleanroom or ride the subway in a hazmat suit.

In order to get any thinking done, you have to accept some probability of being wrong. The question is, how much?
