Cipolla's Laws Of Stupidity

Carlo M. Cipolla was an Italian economic historian who obtained his undergraduate degree  in 1944 from the University of Pavia. Yes, this was during World War 2 in Italy. Subsequently, he studied and worked around the world eventually settling in as a professor at the University of California, Berkeley.

In 1977 he came up with the Fundamental Laws of Stupidity.

1. Always and inevitably, everyone underestimates the number of stupid individuals in circulation.
2. The probability that a certain person (will) be stupid is independent of any other characteristic of that person.
3. A stupid person is a person who causes losses to another person or to a group of persons while himself deriving no gain and even possibly incurring losses.
4. Non-stupid people always underestimate the damaging power of stupid individuals. In particular, non-stupid people constantly forget that at all times and places, and under any circumstances, to deal and/or associate with stupid people always turns out to be a costly mistake.
5. A stupid person is the most dangerous type of person.

    Corollary: a stupid person is more dangerous than a pillager.

These have been on my mind lately. 

In our legal system, I think pillagers are the most common. 

Politically, stupid people dominate.
