Original Darwinian numerical sin

Quantitative reasoning … doesn’t come naturally to any of us. It seems to be our fate to enter this world with lousy quantitative instincts, as if Adam had miscounted the fruit on the tree of knowledge and forced all of us to suffer for his arithmetic sin. Or, to put the same thought in more secular terms, the remote ancestors whose struggle for survival shaped our genetic makeup faced an environment where quantitative skills were not especially important in solving the problem of finding a meal without becoming a meal.
