Do you have a source for “practice makes you better”? Last I checked only N-back benefits from practice, the rest doesn’t.

- Rebelgecko 5y ago"Retest effects in cognitive ability tests" by Scharfen & friends is a good overview that mentions other studies that go into more detail and tweak different parameters (e.g. time between tests, tests that are more repetitive than others, etc). The meta-analysis found that retaking a test can add a couple points each time. So taking an IQ test 4 times on average yields an 8 point increase, almost an entire standard deviation.
- chillacy 5y agoThanks, this actually matches my initial intuition about the matter. It's been awhile since I've looked up info in this area, partly due to the fact that a lot of IQ test proponents I spoke to seemed to have a great deal of personal identity staked in its significance.
