Eugenics has, of course, more ambitious possibilities in a more distant future. It may aim not only at eliminating undesired types, but at increasing desired types. Moral standards may alter so as to make it possible for one man to be the sire of a vast progeny by many different mothers. When men of science envisage a possibility of this kind, they are prone to a type of fallacy which is common also in other directions. They imagine that a reform inaugurated by men of science would be administered as men of science would wish, by men similar in outlook to those who have advocated it. In like manner women who advocated votes for women used to imagine that the woman voter of the future would resemble the ardent feminist who won her the vote; and socialist leaders imagine that a socialist State would be administered by idealistic reformers like themselves. These are, of course, delusions; a reform, once achieved, is handed over to the average citizen. So, if eugenics reached the point where it could increase desired types, it would not be the types desired by present-day eugenists that would be increased, but rather the types desired by the average official. Prime Ministers, Bishops, and others whom the State considers desirable might become the fathers of half the next generation. Whether this would be an improvement it is not for me to say, as I have no hope of ever becoming either a Bishop or a Prime Minister. If we knew enough about heredity to determine, within limits, what sort of population we would have, the matter would of course be in the hands of State officials, presumably elderly medical men. Whether they would really be preferable to Nature I do not feel sure. I suspect that they would breed a subservient population, convenient to rulers but incapable of initiative. However, it may be that I am too sceptical of the wisdom of officials. The effects of psychology on practical life may in time become very great. Already advertisers in America employ eminent psychologists to instruct them in the technique of producing irrational belief; such men may, when they have grown more proficient, be very useful in persuading the democracy that governments are wise and good. Then, again, there are the psychological tests of intelligence, as applied to recruits for the American army during the war. I am very sceptical of the possibility of testing anything except average intelligence by such methods, and I think that, if they were widely adopted, they would probably lead to many persons of great artistic capacity being classified as morons. The same thing would have happened to some first-rate mathematicians. Specialized ability not infrequently goes with general disability, but this would not be shown by the kind of tests which psychologists recommended to the American government.
