“ It's hard to pin down what my actual [IQ] score might be. It's silly to think that people even have one set IQ and that it's precisely measurable. My lowest scores probably reflect less than my maximum effort, and my highest scores probably grant me some extra points due to crazily high levels of diligence plus vast experience with these tests. It doesn't really matter unless we want to turn IQ testing into a reality show sport. ”
