How to Define Stupidity

Unlock the meanings behind words and concepts.


Stupidity can be defined according to Carlo Cipolla's insightful perspective on human behavior. In line with Cipolla's "Basic Laws of Human Stupidity," stupidity refers to actions or behaviors that cause harm to others without generating any personal gain, and potentially even resulting in losses for oneself. It is the inability or unwillingness to make rational decisions that lead to unfavorable outcomes for all parties involved. Stupidity defies logic and reason, often manifesting in repetitive and harmful actions, making those who exhibit such behavior unpredictable and dangerous. Cipolla's definition emphasizes the detrimental impact of stupidity on individuals and society as a whole, shedding light on the need to recognize and navigate the challenges posed by foolishness. He defines his five fundamental laws of human stupidity as follows:

  1. The First Law: Always and inevitably, everyone underestimates the number of stupid individuals in circulation. This law highlights the tendency for people to overlook or underestimate the prevalence of stupidity in society.
  2. The Second Law: The probability that a certain person is stupid is independent of any other characteristic of that person. This law suggests that being a member of a certain group or class does not correlate with the presence or absence of stupidity in an individual.
  3. The Third Law: A stupid person is a person who causes losses to another person or a group of persons while deriving no gain and even possibly incurring losses themselves. Stupidity, as defined by Cipolla, involves actions or behaviors that result in harm to others without any corresponding benefit for the person exhibiting such behavior.
  4. The Fourth Law: Non-stupid people always underestimate the damaging power of stupid individuals. This law highlights the tendency for intelligent individuals to overlook or underestimate the negative impact that stupid individuals can have on society.
  5. The Fifth Law: A stupid person is the most dangerous type of person. Cipolla asserts that stupidity poses a significant threat due to its unpredictable and harmful nature. Stupid individuals, lacking rational decision-making abilities, can create chaos and harm in various contexts.
