>>12473721>first off,A lot of the people on /sci/ are still undergrads, so it's completely believable that the people here have nothing else to show even if they are intelligent. Like, even when you've accomplished things from a young age, I don't go around saying I have fancy certificates & trophies from MathCounts competitions, Scripps spelling bees, the International Scholar Laureate Program, academic institutions like that. It doesn't really make you feel accomplished once you're creeping into adulthood.
>second,Completely legitimate and mostly the case, but I wouldn't put it past a psychological institution to build an IQ test based on online testing. The questions used in an actual IQ test are based on which individual questions are the best indicators of total performance on the test. This is constructed out of data taken from the test itself, so the more people take the test, the more accurate the test becomes. With a fair amount of server-side logic, a Web site can actually produce a true bona fide IQ test on its own, with a sample size that's through the roof. Gatekeep it with a paywall to keep people from retaking the same test, and you have the site being used by OP.
