It's also an odd unsubstantiated claim to make given what he writes earlier (same point is made in book as well):

He told me he began to appreciate the power of intuition, in contrast to what he called “Western rational thought,” when he wandered around India after dropping out of college. “The people in the Indian countryside don’t use their intellect like we do,” he said. “They use their intuition instead … Intuition is a very powerful thing, more powerful than intellect, in my opinion. That’s had a big impact on my work.”
