So argues, persuasively and surprisingly, Charles Murray here.
Because upper-middle-class families produce most of the smartest kids, there is no way to reform the system (short of disregarding intellectual ability altogether) to prevent their children from coming out on top. We can only make sure that high-ability students from disadvantaged backgrounds realize that the nation’s best colleges yearn for their applications and that their chance of breaking out of their disadvantaged situations has never been better—in short, that the system is not rigged. Now, the widespread belief is that the system is rigged, and the SAT is a major reason for that belief. The most immediate effect of getting rid of the SAT is to remove an extremely large and bright red herring. But there are more good effects.
