Final answer:
True, adding even one person to a group can result in more complex relationships due to the changing dynamics and potential for increased intricacy in interaction within primary groups.
Step-by-step explanation:
The statement is true: adding even one person to a group can indeed make the relationships between the group members more complex. In sociology, groups are studied extensively, and it has been observed that each new member can change the dynamics of the group significantly. For example, Georg Simmel discussed the difference between a dyad (a two-member group) and a triad (a three-member group). In a dyad, if one person withdraws, the group ceases to exist, whereas in a triad, the group can live on with the remaining members, and complexities such as a two-against-one dynamic can develop. As you incorporate more individuals into a group, forming what we call primary groups, the web of interactions become more intricate, and the potential for division and lack of cohesion increases. The more attention a larger group can garner, the more pressure members can apply toward a shared goal, but the group also may face increased risk of internal conflict.
