The Sixth Law of Stupidity: A Biophysical Interpretation of Carlo Cipolla’s Stupidity Laws

Abstract

Carlo Cipolla’s stupidity quadrant and his five laws of stupidity were proposed for the first time in 1976. Exposed in a humorous mood by the author, these concepts describe the interactions among human beings in terms of a semiquantitative model based on the gains and losses of the agents engaged in a process. Here, we propose a new interpretation of Cipolla’s ideas in a biophysical framework, using the well known “predator–prey”, or “Lotka–Volterra”, model. We find that there is indeed a correspondence between Cipolla’s approach, based on economics and biophysical economics. We propose a “sixth law of stupidity”, additional to the five proposed by Cipolla, stating that “humans are the stupidest species in the whole ecosystem” because of their tendency of overexploiting natural resources.
