Certain scientific theories do not win acceptance from common understanding. This is the case for Darwin’s theory of evolution. While the characteristics of resistance to it vary by culture – e.g., resistance is not expressed in the same way in France and the United States – resistance is in all cases sustained by more or less implicit specious reasoning. This article, based on in vitro experimentation with 60 subjects, brings to light the beliefs and arguments that impede real diffusion of Darwin’s thesis nearly 150 years after publication of On the origin of species.
