Er, dumb? You do know how IQ is measured, right?
100 is average, I believe the highest ever recorded was about 230 or so, though tests are claimed as "innaccurate" over 145. However, there are apparently a wide number of different IQ tests, of which "high" varies. Its considered better to rank yourself as a percentile, which is done based on the country, however, there's still the problem that I doubt any free IQ test is truly accurate. Usually it costs a small fee to take a legimate IQ test.
Interestingly, IQ really doesn't mean much. I don't consider IQ to mean really anything at all. I go more by knowledge, rather than IQ, which is based more on speed of which they can answer questions (mental agility). I'm sure most of you would feel the same way.
While we're on the topic, what is your opinions of those so called "high IQ clubs"? I consider them pointless, since as I previously stated, IQ tests are not completely accurate, and only measure the "speed" of your thinking, not how much you know, etc; It wouldn't surprise me if some of the smartest people in the world have lower IQ scores. And that would make sense to me too, since surely the smartest people could take the time to double check all their answers, and ensure they are correct and even search for alternative solutions.
