Abstract

The author uses Cournot’s principle as an example to analyze the role of the principles connecting mathematics and reality. Cournot’s principle ensures verification of probabilities for the consequences of the tested hypothesis, using the hypothesis and data under study to deduce the consequences. If the values of these probabilities are less than a minimum permissible value, then the hypothesis is falsified. Therefore, the principle is important for hypothesis testing in mathematical statistics and Popper’s philosophy of science. The article demonstrates that Cournot's principle is not of probabilistic but rather probability-deterministic character.
