While intelligence, or at least the common estimate of it as IQ, is usually asumed to be to normally distributed, there is evidence that this is not exactly correct, particularly with regard to the heavy tails of the distribution (high kurtosis). One study also found a Karl Pearson B1 (skewness) = 0.048, which for this purpose, is sufficient to approximate the median to the average.

What is clear however is that your sense of humour might be below average !

My initial proposition contributes to an explanation as to why half of climbing accidents are the fault of the other bloke.
