A hat-tip to Dave of THIRDWAVEDAVE for this little brain bender! 19/33 is considered genius, well I tried to do this test when I had had no sleep and could only come up with 16/33, but took it again after a really good night's sleep and I was able to get 21/33! So, go try your hand at this Intelligence Test.
Believe it or not, this type of test can be a good estimate of intelligence (if you excuse the cultural bias). People who did well on this type of test are likely those who are gifted with verbal ability and linguistic pattern recognition. This sort of assessment would discriminate against those with non-linguistic pattern recognition (like solving jigsaw puzzles) and spatial intelligence (like the ability to use a map or see hidden figures in a drawing).
