> The way IQ testing is revered and misused arguably does great harm to many. The problem is that I observe the exact opposite in my environment. Take, for instance, hiring for jobs. People are often hired based on unspecified voodoo like bogus personality tests, years of education or the "feeling" you get about a person from a non-standardised interview, which are methods that have been shown to have a large amount of bias and are unreliable for predicting future job performance. On the other hand, we have things that have been shown to have positive, moderate-to-high correlation with job performance, such as standardised interviews, standardised job task test (i.e. putting the person in a test situation mimicking the actual job) and IQ tests. In fact, Taleb himself supplies a figure showing this (https://cdn-images-1.medium.com/max/900/1*RlEAvb8KejpEBFWslwQuGQ.png https://cdn-images-1.medium.com/max/900/1*RlEAvb8KejpEBFWslw...) and half-relies on it to argue that "IQ measures the ability to be a good slave but ignores all of the other implications. Taken together, these tests are an even stronger predictor of job performance. It seems unwise to discard this knowledge based on the kind of emotional drivel that Taleb seems to be displaying here.
