The method of education by information, which was to a great extent relied upon by the United States, for example, was evidenced in the formation during the war of such agencies as the Committee on Public Information. The public relations counsel, through the mediums chosen by him, presented to the public the information necessary to aid in understanding America’s war aims and ideals. George Creel and his organization reached vast groups, representing every phase of our national elements, in every modern method of thought communication. But even in the United States the other two methods were used to obtain cohesive force. In fact the method least relied upon in any of the belligerent countries was that of “government based on such a highly developed system of information, analysis and self-consciousness that ‘the knowledge of national circumstances and reasons of state’ is evident to all men.” This breakdown did not occur among small, inefficiently organised groups. It occurred among the representatives of the highest development in social organization. If this was the fate of the most highly organized social groups, consider then the problem which confronts the social, economic, educational or political groups in peace time, when they attempt to obtain a public hearing for new ideas. Innumerable instances have shown the difficulty that any group faces in gaining an acceptance for its ideas. The development of the United States to its present size and diversification has intensified the difficulty of creating a common will on any subject because it has heightened the natural tendency of men to separate into crowds opposed to one another in point of view. This difficulty is further emphasized by the fact that often these crowds live in different traditional, moral and spiritual worlds. The physical difficulties of communication make group separation greater. Mr. Trotter’s conclusions from a study of the gregarious instinct are singularly apt on this point. He says that[25] “the enormous power of varied reaction possessed by man must render necessary for his attainment of the full advantages of the gregarious habit a power of inter-communication of absolutely unprecedented fineness. It is clear that scarcely a hint of such power has yet appeared, and it is equally obvious that it is this defect which gives to society the characteristics which are the contempt of the man of science and the disgust of the humanitarian.” When the worker was of the same ancestry as his employer, labor difficulties, for example, could be discussed in terms which were comprehensible to both parties. To-day the United States Steel Corporation must exert tremendous effort to present its view to its thousands of employees who are South Europeans, North Europeans, Americans.
