Mental illnesses were thought of as the product of chemical imbalances, or that you’re genetically programmed a certain way. Those concepts have completely entered the culture, and you can’t pick up a publication without some latest genetic explanation of, for instance, schizophrenia. Writing about the science and talking to scientists, you learn that it’s more complicated that that. Genetic transmission can be heavily influenced by the environment itself, and so these cartoonish versions of what directs our behavior are facile. The best scientists are not prone to making these sweeping and simplistic judgments. Eric Kandel, probably the most eminent psychiatrist in this country, writes a lot about the social influence on genes. This can be very dangerous to think of in such simple terms.
