For what reason hasn't anyone come up with correctly normed online IQ tests? I know they're supposed to be administered by professional shrinks but it should be easy to automate the process for recreational use. Same goes for the norming itself thanks to internet itself since there is no real need for credibility.

Yet sites like Mensa, TRI-52 and others give vastly inflated scores. Is it for lack of caring, malice or something else? I guess it might be too much work for such a niche topic but if that were the case you'd think they'd substitute it with a real one, especially when it's provided by org like Mensa.
