The Misunderestimated Man—How Bush chose stupidity:
The most obvious expression of Bush's choice of ignorance is that, at the age of 57, he knows nothing about policy or history. After years of working as his dad's spear-chucker in Washington, he didn't understand the difference between Medicare and Medicaid, the second- and third-largest federal programs. Well into his plans for invading Iraq, Bush still couldn't get down the distinction between Sunni and Shiite Muslims, the key religious divide in a country he was about to occupy. Though he sometimes carries books for show, he either does not read them or doesn't absorb anything from them. Bush's ignorance is so transparent that many of his intimates do not bother to dispute it even in public. Consider the testimony of several who know him well.
Richard Perle, foreign policy adviser: "The first time I met Bush 43 … two things became clear. One, he didn't know very much. The other was that he had the confidence to ask questions that revealed he didn't know very much."
David Frum, former speechwriter: "Bush had a poor memory for facts and figures. … Fire a question at him about the specifics of his administration's policies, and he often appeared uncertain. Nobody would ever enroll him in a quiz show."
Laura Bush, spouse: "George is not an overly introspective person. He has good instincts, and he goes with them. He doesn't need to evaluate and reevaluate a decision. He doesn't try to overthink. He likes action."
Paul O'Neill, former treasury secretary: "The only way I can describe it is that, well, the President is like a blind man in a roomful of deaf people. There is no discernible connection."
A second, more damning aspect of Bush's mind-set is that he doesn't want to know anything in detail, however important. Since college, he has spilled with contempt for knowledge, equating learning with snobbery and making a joke of his own anti-intellectualism. ("[William F. Buckley] wrote a book at Yale; I read one," he quipped at a black-tie event.) By O'Neill's account, Bush could sit through an hourlong presentation about the state of the economy without asking a single question. ("I was bored as hell," the president shot back, ostensibly in jest.)
