Did you know that 50% of people are below averagemedian intelligence?
FTFY
Actually it was already probably correct .
Intelligence has historically been thought to follow a normal distribution. In a normal distribution, the average is the mean is the mode. However, researchers have been finding that the normal distribution actually under-represents the number of people in the high intelligence range. A closer model is probably the Pearson type 5 distribution with a higher average than median.
Of course this is based on naive models of intelligence.
