Paul Tough;

We are living through a particularly anxious moment in the history of American parenting. In the nation’s big cities these days, the competition among affluent parents over slots in favored preschools verges on the gladiatorial. A pair of economists from the University of California recently dubbed this contest for early academic achievement the “Rug Rat Race,” and each year, the race seems to be starting earlier and growing more intense.
At the root of this parental anxiety is an idea you might call the cognitive hypothesis. It is the belief, rarely spoken aloud but commonly held nonetheless, that success in the U.S. today depends more than anything else on cognitive skill–the kind of intelligence that gets measured on IQ tests–and that the best way to develop those skills is to practice them as much as possible, beginning as early as possible.
There is something undeniably compelling about the cognitive hypothesis. The world it describes is so reassuringly linear, such a clear case of inputs here leading to outputs there. Fewer books in the home means less reading ability; fewer words spoken by your parents means a smaller vocabulary; more math work sheets for your 3-year-old means better math scores in elementary school. But in the past decade, and especially in the past few years, a disparate group of economists, educators, psychologists and neuroscientists has begun to produce evidence that calls into question many of the assumptions behind the cognitive hypothesis.
What matters most in a child’s development, they say, is not how much information we can stuff into her brain in the first few years of life. What matters, instead, is whether we are able to help her develop a very different set of qualities, a list that includes persistence, self-control, curiosity, conscientiousness, grit and self-confidence. Economists refer to these as noncognitive skills, psychologists call them personality traits, and the rest of us often think of them as character.

I agree wholeheartedly.
