> We do this in school by separating kids into different classes according to our guess of their ability. Not very reliable, but it can be better overall than treating everyone equally. Measured outcomes are generally worse overall. This system is popular with wealthy/high-status parents though. The way to get better outcomes (in school and society) is to make sure that everyone has enough individual attention and support, not to sort and label everyone. People who are impulsive or who integrate knowledge in a less regular way or ... are not “biologically inferior”; those differences are a complex trade-off, and our society needs a wide variety of personalities and thinking styles to function.
