We refer here to the wide-spread use of trait analyses, both in business and in education, by which a man is estimated on the basis of his tendencies, capacities, and powers. His body is measured for its strength and resiliency, and where defects are discovered, a regimen leading to the re-education of his physique is prescribed. His mental developments are tested, and the common attributes of the human mind, such as sensory acuity, retention, discrimination, and the like, are estimated and recorded. The special talents he possesses are revealed by performance tests, and his hitherto undeveloped potentialities are induced to betray themselves. The emotions from which he either profits or suffers are discovered by methods adroitly devised for the purpose. Likewise, the individual’s sociability,—whether it be merely gang-attachment, or a zest for cooperative endeavors,—is made a matter of sympathetic study; while still other bases upon which a man may be estimated are employed in the attempt to help him find out just what manner of man he is. While it is admitted that physical and mental tests are often stupidly devised and bigotedly inflicted on the testee, yet it seems likely that we have given here a method which can be employed to the greatest advantage even in every-day ethics. For the psychological method, in that it teaches one first to become analytical and discriminative, replaces the old, unfounded prejudice that men are unequivocally either good or bad, virtuous or vicious, saints or sinners, by a desire to know just what can be done with and for them. And while the methods of psychology will probably always rank men on a scale from low to high, and will always employ opposite poles in its judgments, yet in the multitude of such antonyms there is safety. Scientific judgments are, by being unemotional, devoid both of that extreme congratulation and sharp censure which attach to purely moral estimates, while the wide range of observation upon which they are made provides for the greatest number of human contacts and of educative measures possible. To extol a man is often not much different in effect than to blame him, and both praise and blame can equally hinder his power to acquire an ethical technique. Men differ too variously to be fitted to any one Procrustean bed; the human mind has infinitely more than two dimensions. Moreover, the moralist’s use of bi-polar judgments tends inevitably to separate men, rather than to unite them, or to teach them to cooperate with one another. And when we consider that from now on, at least, the predicaments of this planet will be common liabilities of the whole human race, the pragmatic urgency to employ the methods of psychology in attaining social harmony are undisguisedly patent.
