For me, the issue is not the intelligence, but the membership. What is the point in joining a group of people whose only common feature is their test scores? In IQ tests, I consistently score 2 or 3 points below the requirement. A simple rounding error could get me in. Mensa accepts any qualifying score, regardless of how many times you failed to qualify. However, in addition to IQ tests, they also accept GRE scores. On the basis of my scores (from more than 30 years ago), I qualify in a breeze. I suppose the reason for the discrepency is that despite the similarities, these two tests quantify different things. Did you join to meet other people who tested well in their IQ scores, or was it the GRE's that attracted you?
At any rate, I qualify. Now give me one good reason to part with $30 a year. I would get the satisfaction of someone telling me that I am smart. Now that I know I qualify, I've already been told, haven't I? , Anyway, my mother has always said that, and my wife and kids never will. To meet other people who can get the next number in the sequence as well as or better than I, while avoiding those who can't? My mother can't count to three without making two mistakes, can I at least wave to her from the window? My wife, on the other hand, may not do well in those kinds of tests, but she has an intelligence about her that shines in all she does. Can I send her a postcard at least?
