There’s an entire academic field designed around making reliable tests with valid results for psychological measurements, called psychometrics. IQ tests and we swear it’s not an IQ test like SATs, the GRE, GMAT, LSAT are all designed to be as close to ungameable as possible and it works. Practice effects exist, you can get better by doing more of them but they’re also limited. Usain Bolt is never going to run 100m in 5s and I’m never going to run a sub 10s 100m no matter how hard I practice. Likewise SATs are not going to stop predicting success in college or in life because they measure g, the general factor of intelligence. https://en.wikipedia.org/wiki/Psychometrics https://en.wikipedia.org/wiki/G_factor_(psychometrics) |
