>>11613007IQ tests measure your education level, that's why your IQ increases. You look at any IQ tests and you realize most of the patterns and questions are learned in school. When you have tests that ask you about similarity or differences between words, it's about the definition of words, which are learned in school. When you're asked logic questions such as if X then Y and if Y then Z, then is if X then Z correct? then you're looking at mamthematical logic, which is learned in school. When you have questions like sally is X times older than john, when sally is X years old, how old is sally when john is Y years old, it's algebra and learned in school. When you have pattern questions such as two grid with dots resulting in a third grid with dots, and the pattern is adding the dots (equivalent of OR operation) in both previous grids together, subtracting them (NAND), or so on, it's boolean algebra, and once again learned in school. When you have patterns that rotate, translates, permutates and so on, it's math and learned in school. When you have sequences with a pattern between each previous number, it's once again math and learned in school. In other words, the tests measures knowledge, and how well you do on those depends on how far along you are in your education and how much practice you had. I'm pretty sure everyone here can do algebra in their sleep, but also struggled at least a bit with algebra back in high school. You surely didn't get 100% in all your math exams back in high school, even though you probably could get 100% now. Has your IQ risen? Or have you gotten better through practice? if you could put a 4th year university math question into an IQ test format, I'm sure that virtually everyone who isn't a math major wouldn't be able to solve it, and most math majors would struggle, whereas people with Ph.D in math would find it a lot easier.
