Card 3 of 5 · 5 Laws of Stupidity
Cipolla definition of stupidity (Third Law - The Definition)
Loss to you, no gain to them.
Cipolla's definition of stupidity, which he called the golden law, is purely about results. A person acts stupidly when they cause losses to someone else and get no benefit in return, sometimes hurting themselves as well. It has nothing to do with IQ or education.
Cipolla placed this inside a simple grid with two questions: does the action help or hurt the person doing it, and does it help or hurt others? Intelligent actions help both sides. Helpless actions hurt the actor but help others. Bandits gain at others' expense. Stupid actions hurt everyone. The grid makes the concept measurable instead of a matter of taste.
The common error is to use the definition as a weapon in arguments. Someone disagrees with you or harms your interests, so you call them stupid. Usually that is wrong. If they gained something from the situation, they fit the bandit box, not the stupid one. Being strict about both conditions, real loss to others and no real gain to the actor, keeps the tool honest.
Seeing the grid also helps you look at yourself. Many of our worst moments, a petty email or a pointless fight, fall into the stupid box. Catching that is the first step to avoiding it.
Example
A neighbour parks across two spaces out of spite after a minor dispute. Nobody else can park, and he gets ticketed too. Everyone loses and he gains nothing. That is Cipolla's stupid quadrant. If instead he had taken the space to be closer to his door, he would be a bandit.

Before reacting to someone who annoyed you, ask whether they gained anything, and sort their action into one of Cipolla's four boxes.
