Intelligence and How To Get It

From the New York Times review of Richard Nisbett's book

But beyond a certain threshold — an I.Q. of 115, say — there is no correlation between intelligence and creativity or genius. As more of us are propelled above this threshold — and, if Nisbett is right, nearly all of us can be — the role of intelligence in determining success will come to be infinitesimal by comparison with such “moral” traits as conscientiousness and perseverance. Then we can start arguing about whether those are genetic.

Innate intelligence as measured by IQ can be increased

IQ is not the most important success factor
