The answer is "That intellect and achievement are far from perfectly correlated." So, yes it is correct.
Outliers are these individuals who all had help en route, were given a unique opportunity and they seized it. But achievement isn't about chances of a lifetime; it's perceiving and seizing on one's chances. In tending to the effect of knowledge on progress, Gladwell composes that "the relationship between success and IQ works only up to a point", and after that intellect and accomplishment are a long way from impeccably associated. Expecting no less than a normal IQ, for more elevated amounts of achievement, something named "practical intelligence" is important, including realizing what to state to whom, knowing when to state it, and knowing how to state it for most extreme impact (none of which can precisely be checked by one's IQ level).
