It is rather surprising that systematic studies of human abilities were not undertaken until the second half of the last century… An accurate method was available for measuring the circumference of the earth 2,000 years before the first systematic measures of human ability were developed.

Do not put your faith in what statistics say until you have carefully considered what they do not say.

William W. Watt

I could prove God statistically. Take the human body alone - the chances that all the functions of an individual would just happen is a statistical monstrosity.
