Society is made up of an almost infinite number of groups, whose various interests and desires overlap and interweave inextricably. The same man may be at the same time the member of a minority religious sect, supporter of the dominant political party, a worker in the sense that he earns his living primarily by his labor, and a capitalist in the sense that he has rents from real estate investments or interest from financial investments. In an issue which involves his religious sect he will align himself with one group. In an issue which involves the choice of a President of the United States he aligns himself with another group. In an industrial issue between capital and labor it might be very nearly impossible to estimate in advance how he would align himself. It is from the constant interplay of these groups and of their conflicting interests upon each other that progress results, and it is this fact that the public relations counsel takes into account in pleading his cause. A movement called “The Go-Getters,” instituted by a magazine, as much to keep itself before the public eye as to stimulate commercial activity, found rapid acceptance throughout the country because it appealed to trades of every description, because each group had among its members men who belonged also to a large group, the group of salesmen. Let us examine for a moment the personnel of the Horseshoe at the Metropolitan Opera House. It is composed of people who are rich, but this economic classification is only one, for the men and women who assemble there are presumably music lovers. But we may again break up this classification of music lovers and discover that this group contains art lovers as well. It contains sportsmen. It contains merchants and bankers. There are philosophers in it. There are motorists and amateur farmers. When the Russian Ballet came to America the essential parts of this group attended the performances, but in going after his public, the public relations counsel based his actions upon the interlapping of groups, and appealed to his entire possible audience through their various interlapping group interests. The art lover had been stimulated by hearing of the Ballet through his art group or the art publications and by seeing pictures of the costumes and the settings. The music lover, who might have had his interest stimulated through seeing a photograph, also had his interest stimulated by reading about the music. Every individual heard of the Russian Ballet in terms of one or more different appeals and responded to the Ballet because of these appeals. It is naturally difficult to say which one of them had its strongest effect upon the individual’s mind. There was no doubt, however, that the interlapping group formation of society made it possible for more to be reached and to be moved than would have been the case if the Ballet had been projected on the world at large only as a well-balanced artistic performance.
