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.
Thus, about 0.15% of a population should have an IQ score above 145 (and 0.15% a score below 65). Note that this estimate is not inclusive of 145 but is neverthless a decent estimate.bout two thirds of people have an IQ within 1 standard deviation of 100 (the mean). For example, IQ tests commonly have a standard deviation of about +/-15. This means about two thirds of people have an IQ between 85 and 115. You might call this the average range.
