That's a common lay criticism of IQ tests, but it's not at all common among clinical practitioners or psychologists. It's also completely at odds with the outstanding literature on the subject[1]. There is broad clinical and professional consensus that IQ tests are both statistically reliable and valid for a number of generally useful measurements of cognitive ability. I think you can make a compelling case that IQ tests can be misused as a hiring filter - for example, you might not need to hire people who score highly on it. But as a standalone assessment, modern literature doesn't leave much room for debate on its psychometric merit. ____________________________________________ 1. https://www.apa.org/pubs/journals/releases/amp-67-2-130.pdf https://www.apa.org/pubs/journals/releases/amp-67-2-130.pdf
