The "trickle-down" theory: the principle that the poor, who must subsist on table scraps dropped by the rich, can best be served by giving the rich bigger meals.
There is one brain organ that is optimised for understanding and articulating logical processes and that is the outer layer of the brain, called the cerebral cortex. Unlike the rest of the brain, this relatively recent evolutionary development is rather flat, only about 0. 32 cm (0. 12 in) thick and includes a mere 6 million neurons. This elaborately folded organ provides us with what little competence we do possess for understanding what we do and who we do it.
