The old moral model dies hard. It still lives on in the minds of certain groups and individuals. At the heart of the moral model beats the conviction that willpower controls all human emotion, learning, and behavior. Under this model, the cure for depression is to cheer up. The cure for anxiety is to suck it up. And the cure for ADD is to try harder. While trying harder helps just about everything, telling someone with ADD to try harder is no more helpful than telling someone who is nearsighted to squint harder. It missed the biological point.
