I know that I am beating a dead horse. It is a personality flaw of mine. I am bothered by the number of 160-200+ IQ numbers listed there, however. Modern tests don't return numbers like that. Maybe all of the older composers and presidents had IQs at the 99.9th percentile, but I doubt it. I don't doubt that Mozart was gifted. Do I think that someone gave him an IQ test? Probably not. Then again, no one needed to. I think that's why, as someone indicated earlier, gifted is not all about IQ and why DYS, for instance, requires more than an IQ score for admission.
Mensa, on the other hand, only wants your IQ in the 130+ range for admission. I joined solely b/c I thought they might have some useful info for me in learning how to best support my eldest dd when we figured out what was going on with her. I remain a member b/c I've met some good friends through Mensa and some of us get together regularly (and I enjoy the monthly publication).
FWIW, just b/c a website says that these people are confirmed members of Mensa, doesn't make it so. Just looking over the nine show biz people they list, only one of them is listed in the member directory as a member. One of the people listed there without the confirmation star
is a Mensa member. None of the famous people in sports nor famous musicians are. I'll allow for the fact that the Welsh wrestler might be a member of an international Mensa chapter and his name, thus, wouldn't appear on American Mensa's roster. The member directory does note that all current members must have their names listed there although other information is at their discretion.
