The fingers have two long flexors, located on the underside of the forearm. They insert by tendons to the phalanges of the fingers. The deep flexor attaches to the distal phalanx, and the superficial flexor attaches to the middle phalanx.
An adult can only get a maximum IQ of 161 on the Cattell III B test and 183 on Culture Fair. A top two per cent score on Cattell III B would be 148 or over, while for Culture Fair it is 132 or over. The two papers test different types of IQ.
However, an individual scoring 100 within one population can score above or below that value within another population, for example, the Japanese are supposed to have the highest average IQ in the world (115), but this 115 can only be an average of 100 within their own population.
