85 Reading: Group Size and Structure
Dyads, Triads, and Large Groups
A small group is typically one where the collection of people is small enough that all members of the group know each other and share simultaneous interaction, such as a nuclear family, a dyad, or a triad. Georg Simmel (1858–1915) wrote extensively about the difference between a dyad, or two-member group, and a triad, which is a three-member group (Simmel 1902). In the former, if one person withdraws, the group can no longer exist. We can think of a divorce, which effectively ends the “group” of the married couple or of two best friends never speaking again. In a triad, however, the dynamic is quite different. If one person withdraws, the group lives on. A triad has a different set of relationships. If there are three in the group, two-against-one dynamics can develop, and there exists the potential for a majority opinion on any issue. Small groups generally have strong internal cohesiveness and a sense of connection. The challenge, however, is for small groups to achieve large goals. They can struggle to be heard or to be a force for change if they are pushing against larger groups. In short, they are easier to ignore.
It is difficult to define exactly when a small group becomes a large group. Perhaps it occurs when there are too many people to join in a simultaneous discussion. Or perhaps a group joins with other groups as part of a movement that unites them. These larger groups may share a geographic space, such as a fraternity or sorority on the same campus, or they might be spread out around the globe. The larger the group, the more attention it can garner, and the more pressure members can put toward whatever goal they wish to achieve. At the same time, the larger the group becomes, the more the risk grows for division and lack of cohesion.
