The SAT is a scam. It has been around for 50 years. It has never measured anything. And it continues to measure nothing. And the whole game is that everybody who does well on it, is so delighted by their good fortune that they don’t want to attack it. And they are the people in charge. Because of course, the way you get to be in charge is by having high test scores. So it’s this terrific kind of rolling scam that every so often, somebody sort of looks and says—well, you know, does it measure intelligence? No. Does it predict college grades? No. Does it tell you how much you learned in high school? No. Does it predict life happiness or life success in any measure? No. It’s measuring nothing.
