text: are there any good sites that have tests which measure your cognitive functionality?   there are plenty of sites that do that but they're all total bs.  many of them will claim things like "the average score of people who took this iq test was 125."  no, if the average iq for the entire sample of a given test is not exactly 100 there's something seriously wrong with their scoring system.  and then people take them and think their iq is like 145 (this would be less than 0.5% of the population, but i've seen several people on here claim that that's what they got) when they couldn't even figure out that online iq tests are useless.  i talked about iq tests specifically because there are so many of them, but the same applies to just about any online test.
