"Normal distributions are not the norm."

Non-Normal Distributions in the Real World
"After nearly two decades of research involving thousands of real-world manufacturing and nonmanufacturing operations, I have an announcement to make: Normal distributions are not the norm.
You can easily prove this by collecting data from live processes and evaluating it with an open mind. In fact, the early quality pioneers (such as Walter A. Shewhart) were fully aware of the scarcity of normally distributed data. Today, the prevailing wisdom seems to say, 揑f it ain抰 normal, something抯 wrong.? That抯 just not so."
(Read the whole story directly on the site it's funny)
So if you knew the philosophy of Walter Shewart you would find that all the debates about Normal Law is ridiculous because it is normal that Normal Law is not so normal

This is course true for every nation.
