Is IQ an excellent "predictor of income, social status, and academic & job performance" or merely associated with those?
- nokcha 9y agoIQ can be measured in middle school (before the student has a job or income), and the resulting score can be used to predict future income and job performance. In that sense, it is a predictor rather than a mere association.
- techman9 9y agoOk, but there are still myriad confounding factors, even at that age. Do students from higher income schools in aggregate have higher IQs than those from lower income schools?
- throwaway337 9y agoAll of these things are controlled for. These are professors whose job it is to make sure you don't have such confounding variables. You even have twin studies where one twin was adopted by rich and one by poor parents and it still holds.
