The stakes are low. If I’m wrong about something specific, it’s (usually) my own fault, and someone else is (usually, but not totally) right. But what about the things we’re all wrong about? What about ideas that are so accepted and internalized that we’re not even in a position to question their fallibility? These are ideas so ingrained in the collective consciousness that it seems foolhardy to even wonder if they’re potentially untrue. Sometimes these seem like questions only a child would ask, since children aren’t paralyzed by the pressures of consensus and common sense.
