Always and inevitably everyone underestimates the number of stupid individuals in circulation.

Second Law:

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.

Fourth Law:

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.

Decius:

Stupid people like stupid black and white choices. They are blinded by their convictions.
