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 wrote extensively about the difference between a dyad, or two-member group, and a triad, which is a three-member group. In the former, if one person withdraws, the group can no longer exist. The intensity is high but stability is low because the dyad is dependent upon both people being committed to the group of two. 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. Intensity is lower but stability is higher because 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. Consider a dyad (couple) that becomes a triad (new baby). We can often see a lessening of the intensity between parents as attention is diverted to a newborn who requires a lot of time and care. Often, the partner who does less caregiving (perhaps the male) feels left out and is less clear about their role in the group (family) and the person who does more caregiving (perhaps the female) might feel pulled too thin and find it difficult to give their partner and the new baby enough time and attention without feeling depleted. Similarly, when couples see their children off to college and experience an "empty nest," the dyad might feel like a new group with the intensity of a group of two resurfacing and stability decreasing now that children are no longer living in the home.

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 exert in the pursuit of goals the group wishes to achieve. At the same time, the larger the group becomes, the more the risk grows for division and lack of cohesion.
