The idea is ancient and familiar, its present interest arising largely from a tendency to apply it more and more stringently in the control of economic competition. It appears here in a great variety of forms, but the general aim is to classify more definitely the kinds of economic struggle, to determine who are and who are not legitimate participants in each, and to see to it that all are carried on under proper rules for the protection of the weak and the welfare of the public. All competent students feel that there is urgent need of a rational programme for the protection from crushing and degradation of those who, for whatever reason, are not in a position to protect themselves. If their weakness is intrinsic they need to be removed from the general struggle and put in a class by themselves; if it is accidental they require intelligent succor while they are recovering their strength. The weak side of the standardization idea, as applied to society, is its trend toward the numerical and mechanical. An external, visible test, almost always superficial in this sphere, is easy to apply, and for that reason recommends itself to all who seek precise results without an exercise of the higher faculties of the mind. This, added to the prestige which numerical methods have gained by their value to physical science, has given rise to a formalism which intrudes them where they do not belong, and inspires a confidence in results often in inverse ratio to their value. To the statistical type of mind precision is apt to seem in itself a guaranty of truth, and it is common to see elaborate calculations based on assumptions which will not bear scrutiny. The authors of such structures instinctively avoid any kind of thinking except mathematical. This was partly the case with Francis Galton, a man of real eminence, who made a statistical study of men of genius, in which the numerical part is logically dependent upon the postulate that practically all men of genius become famous.[81] This view he does not examine adequately; the bent of his mind unfitted him to do so. He had to have a standard test of genius in order to open the way for statistical treatment; and he easily convinced himself that fame was such a test. His postulate, however, is pretty clearly false, and his calculations, consequently, of doubtful value. Many accept numerical system and precision as “science” without further inquiry. I have seen a university faculty adopt without question a resolution recommending as scientific the distribution of examination marks according to the statistical curve of chance variations from a mean, when probably few if any of those present had asked themselves whether it was likely, in common sense, that the performances of the students followed any such law.
