Now that really is a taboo word. You must never call anyone stupid! But aren’t some people just plain stupid? And isn’t stupidity the source of much of the world’s misery? I’d like to see a “Stupidity Science” movement in which the phenomenon is studied and taxonomized and explained–and remedied. I am certainly not a relativist about stupidity; I think stupidity is an objective trait. Maybe we all all stupid sometimes–but some people are stupid a lot of the time. Stupidity, as I mean it here, refers especially to the opinions and utterances of people who should know better. As the old saying goes: “It would only take a minute’s thought…but thought is a difficult thing and a minute is a long time.” In the end, of course, stupidity is about character, not IQ.
