I’ve always wondered why you never get to see the actual questions or your answers after taking a professionally administered IQ test. With school tests or online exams, you can usually review what you got right or wrong. But with the WAIS, Stanford–Binet, or similar tests, everything is locked down.
Is it just to prevent people from memorizing the items? Or is there a deeper psychometric reason, like protecting test validity or preventing item exposure from messing up the norms? It feels a little strange that you can spend hours doing a test but never see any of the material again.
Reply: It’s mainly to protect test security and validity. If people could review questions afterward, items would spread through social media, tutoring services, and online forums, making the test less accurate for future test-takers. IQ tests cost millions to develop and validate, and once items become public, they lose their diagnostic value—people could practice specific questions rather than genuinely demonstrating their cognitive ability. That’s why test materials are tightly controlled and only licensed psychologists can access them. It’s frustrating, but it’s necessary to keep the tests fair and accurate for everyone.
