Poverty is the proof of deficiencies, including an intellect that is “fixed.” Dweck’s research challenges this belief. She shows that when children think that their intellectual abilities can improve, they are more likely to work hard. And working hard allows the brain to “grow,” by strengthening its neural connections. If they labor over a math problem, even with frustration, their brains are getting “stronger,” says Dweck. This makes struggle a good thing—not a sign of stupidity but a path to intellect.
