Of course a large number of random events do tend to form known patterns/distributions. Go read any introductory statistics books - and pay particular attention to the chapters on random walks and outcome distributions.
Again, the nature of this conversation is "why" something happens. So saying it happens and it's statistics is not a rebuttal to me suggesting a possible explanation as to why it might happen.
This will be my last response in this thread - it seems to be degrading into a flame war. If you want more info email me (my address is in my profile).
I wasn't saying 'statistics' as a magical name, I was just using it as shorthand for the explanation that it provides. Frankly, I don't have the time or inclination to type up a half hour lecture on stats (especially since there are thousands of others who have already done so far better than I could).
But, here's the 10 second explanation:
Many easily measurable outputs (height, weight, wealth, etc) are functions of a large number of roughly randomly distributed inputs. It's very unlikely that all these inputs are lined up in such a way that the observable output is maximized or minimized. It's much more likely that they will, in fact, on average cancel each other out. Given a sufficient number of trials (i.e., a large enough population), this results in a normal/guassian/bell-curve distribution of the observable output.
Given other distributions/correlations of inputs you get the other common distributions of outputs (lognormal, boltzmann, exponential, etc).
