Note that employers aren't allowed to measure and discriminate on IQ, but they are allowed to look at which college a candidate went to. Your statement is factually incorrect, but surely honestly made (as I used to have the same misimpression of the law in the United States). You received a bunch of replies (as subreplies) on the point of companies using college graduation as a proxy for IQ. I am trained as a lawyer. Even after I was in law practice, I still had the (mistaken) belief that the holding of the Duke Power case was as you say here (and several subreplies say below). But that is NOT the correct holding of the Duke Power case. In fact, the case held that educational requirements (in the case, those were high school diploma requirements) are just as legally suspect as IQ tests not validated for that job in that workplace if the diploma requirements have disparate impact on different racial groups applying for jobs in that workplace. On the other hand, either an IQ test or a diploma requirement can pass legal scrutiny if it can be shown to be related to bona fide job requirements. I have a FAQ on the topic[1], which is one of my most popular Hacker News comments ever. [1] https://news.ycombinator.com/item?id=4613543 https://news.ycombinator.com/item?id=4613543
