The probability that a certain person be stupid is independent of any other characteristic of that person.

Whenever I analyzed the blue-collar workers I found that the fraction σ of them were stupid. As σ's value was higher than I expected (First Law), paying my tribute to fashion I thought at first that segregation, poverty, lack of education were to be blamed. But moving up the social ladder I found that the same ratio was prevalent among the white-collar employees and among the students. More impressive still were the results among the professors. Whether I considered a large university or a small college, a famous institution or an obscure one, I found that the same fraction σ of the professors are stupid. So bewildered was I by the results, that I made a special point to extend my research to a specially selected group, to a real elite, the Nobel laureates. The result confirmed Nature's supreme powers: σ fraction of the Nobel laureates are stupid.
