Homans said, “If we wanted to establish the reality of a social system as a complex of mutually dependent elements, why not begin by studying a system small enough so that we could, so to speak, see all the way around it, small enough so that all the relevant observations could be made in detail and at first hand?” He fulfilled this study throughout "The Human Group". This book allowed him to make certain generalizations, including the idea that the more frequently people interact with one another, when no one individually initiates interactions more than others, the greater is their liking for one another and their feeling of ease in one another's presence. Although this wasn't Homans' greatest piece of work, it allowed him to become more familiar with this type of methodology and led him to explain elementary social behavior.
