What about the central limit theorem? I was referring to physical
human features - such as height - and the example of Napoleon's army
candidates for draft. In an army of millions of soldiers - you would
expect a normal distribution of heights. The problem is that those who
tried to avoid drafting probably bribed somebody to write false
heights, which is shorter than the minimal required height. In this
case - you might get a skewed distribution of heights
