Cipolla produced two non-technical, popular essays that circulated in English among friends in 1973 and 1976. The second essay, "The Basic Laws of Human Stupidity" ("Le leggi fondamentali della stupidità umana", 1976),[3][4] explores the controversial subject of stupidity.
These are Cipolla's five fundamental laws of stupidity:
- Always and inevitably, everyone underestimates the number of stupid individuals in circulation.
- The probability that a certain person (will) be stupid is independent of any other characteristic of that person.
- 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.
- 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.
- A stupid person is the most dangerous type of person.
As is evident from the third law, Cipolla identifies two factors to consider when exploring human behavior:
- Benefits and losses that individuals cause to themselves.
- Benefits and losses that individuals cause to others.
Cipolla further refines his definition of "bandits" and "naïve people" by noting that members of these groups can either add to or detract from the general welfare, depending on the relative gains (or losses) that they cause themselves and society.
A bandit may enrich himself more or less than he impoverishes society, and a naïve person may enrich society more or less than he impoverishes himself and/or allows himself to be impoverished.
