"As I later thought about the bowling contest, I became convinced I had discovered something important: the relationship between individual performance and group structure. I believed then that this relationship can be observed in all manner of group activities."

“Home plays a very small role in the group activities of the corner boy. Except when he eats, sleeps, or is sick, he is rarely at home, and his friends always go to his corner first when they want to find him. Even the corner boy's name indicates the dominant importance of the gang in his activities. It is possible to associate with a group of men for months and never discover the family names of more than a few of them. Most are known by nicknames attached to them bv the group. Furthermore, it is easy to overlook the distinction between married and single men. The married man regularly sets aside one evening a week to take out his wife. There are other occasions when they go out together and entertain together, and some corner boys devote more attention to their wives than others, but, married or single, the corner boy can be found on his corner almost every night of the week.”

“They were always calling police stations telling them. 'There is a riot in the Northon street settlement. Send the riot squad right away.' A couple of cops would come down and joke with the boys , because they were good friends.”

“I must confess at the outset that I never felt at ease in dealing with Smith. Perhaps my insecurity stemmed in large part from my youth and lack of much previous experience in dealing with management people. Beyond this, Smith was known even to his associates as “a hard fellow to get to know.” He did not encourage informality. My meetings with him were generally held in his office, with an atmosphere of strictly business. Even when we had lunch together, the businesslike atmosphere prevailed. Had I been able to see him more than once a month, it might have been possible to reduce these barriers, although I am convinced that much of the problem would still have remained.”

“An organic system is like a fountain balanced upon a pyramid of fountains.”

“Each member of the corner gang has his own position in the gang structure. Although the positions may remain unchanged over long periods of time, they should not be conceived in static terms. To have a position means that the individual has a customary way of interacting with other members of the group. When the pattern of interactions changes, the positions change. The positions of the members are interdependent, and one position cannot change without causing some adjustments in the other positions. Since the group is organized around the men with the top positions, some of the men with low standing may change positions or drop out without upsetting the balance of the group. For example, when Lou Danaro and Fred Mackey stopped participating in the activities of the Nortons, those activities continued to be organized in much the same manner as before, but when Doc and Danny dropped out, the Nortons disintegrated...”

“Without this combination of research methods, it is hard to imagine how this theoretical advance could have been achieved. If I had only relied on the anthropological studies, I would not have believed a student's report when professional anthropologists provided conflicting interpretations of the same community. Relying on the survey data alone, it would not have occurred to me to check the correlations between perceptions of conflict and perceptions of cooperation. If I had found a zero correlation, I could not have known how to interpret it.”
