Stupidity is a quality or state of being stupid, or an act or idea that exhibits properties of being stupid.

These are Cipolla's five fundamental laws of stupidity:

1. Always and inevitably each of us underestimates the number of stupid individuals in circulation.
2. The probability that a given person is stupid is independent of any other characteristic possessed by that person.
3. A person is stupid if they cause damage to another person or group of people without experiencing personal gain, or even worse causing damage to themselves in the process.
4. Non-stupid people always underestimate the harmful potential of stupid people; they constantly forget that at any time anywhere, and in any circumstance, dealing with or associating themselves with stupid individuals invariably constitutes a costly error.
5. A stupid person is the most dangerous type of person there is.

We the people believe stupidity is  not something that should be past on from  generation to generation, so stupid people please use birth control.
