Precisely because, as you said, "it doesn't work." There's not a good amount of evidence that IQ tests (which vary wildly, BTW) are a valid measure of cognitive ability or an indicator of aptitude toward a task (perhaps other than mental arithmetic or something). It only causes people who may be bad at rotating shapes in their mind or whatever to be discriminated against.
- toomim 5y agoYou might want to read up on general intelligence, which is the well-documented phenomena that your performance on tasks like rotating shapes in your mind correlates very strongly with other tasks: https://en.wikipedia.org/wiki/G_factor_(psychometrics) https://en.wikipedia.org/wiki/G_factor_(psychometrics) Look at the figures in the "Cognitive ability testing" section -- see how strong those correlations are across the disparate fields of Classics, Math, and Music! In other words, there is a mountain of evidence that IQ tests correlate with an extraordinarily broad range of aptitudes in daily life, and especially with job performance. IQ is the single most important psychometric correlate with job performance and income of any out there; it's a much stronger signal than race, gender, birthplace, or personality for instance: "Research indicates that tests of g are the best single predictors of job performance, with an average validity coefficient of .55 across several meta-analyses of studies based on supervisor ratings and job samples."
