Back in 1988, after moving to a new area, I thought I'd take a British Mensa IQ test to find out my IQ and then perhaps be able to get in touch with intelligent people. On both the practice test and the supervised test Mensa said that my Cattell-scale IQ was 161 (equivalent to about 141 on Stanford-Binet and corresponding to the top 0.5%), so I was in. I was a bit disappointed to find it wasn't any higher given some less formal results and rumours from my youth, but on the other hand 1 in 200 meant it might be easier than I had previously feared to find similarly intelligent people. I went to a few meetings and activities, but never seemed to find any really shared interests, and later met more interesting people through music (including the person who is now my wife). So much for Mensa. Anyway I only just discovered today from British Mensa's own website that 161 is the maximum Cattell IQ which British Mensa actually quotes as a result for the adult test, in that any raw scores for that particular test above that level are assumed to be insufficiently reliable to assign a specific IQ. I never heard anything about this before. So that means that back in 1988 when they told me my IQ, what they should really have told me is that my IQ was greater than or equal to that value and that if wanted to know it more accurately I'd need to find some other test. So I've been under the illusion for 20 years that they had measured my IQ but in fact they'd set only a lower limit on it. That really makes me feel stupid! Anyway, I'm sure it's too late to do anything about it now. With the frustration and stress of my current job, as well as far too frequent headaches, I barely have the intelligence to work out the surface volume of a 4-dimensional black hole, let alone how to operate the timer on my cooker. So if you take an IQ test, make sure that your precise numeric result isn't just an "off-scale" reading. And can anyone here actually recommend any higher-IQ associations (I guess I qualify for 99.5% percentile), or are they all based on the fallacy that being intelligent is somehow a shared interest?
