From Mensa "
As different IQ tests were developed, each was given its own scoring system. Therefore, an IQ of 150 is a meaningless claim unless you know the actual test which was used."
Mensa. So, I repeat the question, which test did you sit, as unfortunately, in Mensa words, the claim is 'meaningless' without knowledge of the test used. Mensa UK itself uses two different ones. So a quick explanation of the type of test will suffice. As a score on Ravens Standard of 131 would get you in Mensa, but not in the top 1% of the entire planet, but you would need 148 on Catell IIIB. So, which test, and what was the format, and where did you go to get tested for those 12 years?
Oh, and what was your raw scores for those years? You know, just for validation purposes.
That sequence of numbers right in you post, the last three should be 100, 101, 102.
The world population bit, ask Emma, that statistic only works if every person on the planet has been tested (or at least a large representative sample from different cultures, ethnicities and background), and I know for a fact that my son hasn't, nor has my daughter, nor have 3 of the 5 people in my office, I asked them today. I am afraid it sits in with "Did you know 87% of statistics are made up on the spot" for accuracy.
