Summing it all up we may say that K responds normally to simple situations directly sensed, and that his inferiority is chiefly evident in responses involving intellectual initiative, planning, range and flexibility of association, analysis of a situation into its elements, alertness, and the direction of attention toward the significant aspects of experience. Most of all, K is stupid because he is not adept in the formation and manipulation of concepts; because he is unable to master the intellectual shorthand of general ideas.

It is now fairly well established that the strictly median individual of our population meets with little success in dealing with abstractions more difficult than those represented in a typical course of study for eighth grade pupils, that the large majority of high-school graduates are drawn from the best 25 per cent. of the population, and that the typical university graduate ranks in intellectual endowment well within the top 10 per cent. K is stupid only by contrast. Only occasionally does an individual of his moderate ability manage to graduate from high school or enter college.
