As I understand it (please correct me if I'm wrong) IQ tests work as a predictor for a population not for individuals. I.e. if you prefer IQ in your job application process, you will get a more performative workforce. However, with point samples it's not a very good benchmark. I.e. if you are comparing fairly strong candidates A and B, just preferring the one with the higher IQ is not necessarily the best option. So, getting the best hire for a specific position, and getting the most statistically best workforce are not necessarily the same thing.
