From “Mindset: The New Psychology of Success” by Carol S. Dweck, PhD
Who’s right? Today most experts agree that it’s not either – or. It’s not nature or nurture, genes or environment. From conception on, there’s a constant give-and-take between the two. In fact, as Gilbert Gottlieb, an eminent neuroscientist, put it, not only do genes and environment cooperate as we develop, but genes require input from the environment to work properly.
At the same time, scientists are learning that people have more capacity for lifelong learning and brain development than they even thought. Of course, each person has a unique genetic endowment. People may start with different temperaments and different aptitudes, but it is clear that experience, training, and personal effort take them the rest of the way. Robert Sternberg, the present-day guru of intelligence, writes that the major factor in whether people achieve expertise “is not some fixed prior ability, but purposeful engagement.” Or, as his forerunner Binet recognized, it’s not always the people who start out the smartest who end up the smartest.
