" "The “IQ fundamentalist” Arthur Jensen put it thusly in his 1980 book Bias in Mental Testing (p. 113): “The four socially and personally most important threshold regions on the IQ scale are those that differentiate with high probability between persons who, because of their level of general mental ability, can or cannot attend a regular school (about IQ 50), can or cannot master the traditional subject matter of elementary school (about IQ 75), can or cannot succeed in the academic or college preparatory curriculum through high school (about IQ 105), can or cannot graduate from an accredited four-year college with grades that would qualify for admission to a professional or graduate school (about IQ 115). Beyond this, the IQ level becomes relatively unimportant in terms of ordinary occupational aspirations and criteria of success. That is not to say that there are not real differences between the intellectual capabilities represented by IQs of 115 and 150 or even between IQs of 150 and 180. But IQ differences in this upper part of the scale have far less personal implications than the thresholds just described and are generally of lesser importance for success in the popular sense than are certain traits of personality and character.

Additional quotes by Malcolm Gladwell
The scholars who research happiness suggest that more money stops making people happier at a family income of around seventy-five thousand dollars a year. After that, what economists call “diminishing marginal returns” sets in. If your family makes seventy-five thousand and your neighbor makes a hundred thousand, that extra twenty-five thousand a year means that your neighbor can drive a nicer car and go out to eat slightly more often. But it doesn’t make your neighbor happier than you, or better equipped to do the thousands of small and large things that make for being a good parent.
Washington in 1965. We instinctively measure advantage in terms of the three M’s because men, money, and matériel are the easiest and most obvious ways to make sense of a battle. The only way to appreciate the threat that the Viet Cong posed was to actually listen to what they had to say — to look past the armor and see the man. The book you have just read has tried to persuade you to think that way. Men, money, and matériel aren’t always the deciding factors in a battle. In fact, what the inverted U-shaped curve tells us is that having too much money and matériel is as debilitating as having too little. Being an underdog — having nothing to lose — opens up possibilities. The Impressionists were better for shunning the Salon. History and experience ought to teach us to be suspicious of Goliaths, because the very thing that makes the giant so terrifying is also the source of his weakness. David understood that, as he sized up his opponent long ago in the Valley of Elah.
