Ij101 - Sorry, can't discuss the mensa forums, they have a rule about that. But if you consider the normal distribution (bell-shaped curve) and truncate it on the 98th percentile, the remainder is a very strange shape, with most of the population at the lowest extreme. Those of us who get banned seem to reside in the tiny minority at the higher end.
All completely meaningless in real life. Except electronics, where IQ is actually useful.
