What the author says is sometimes true, but for a very small proportion of the underachievers. A very large proportion of the underachievers, however, will think that they are part of that small proportion. It is the same with IQ: IQ and cleverness are not always very well correlated, but those with a high IQ will think that there is more correlation than there is while those with a low or average IQ will think that there is less.
