According to Kelly, the minimum number of events required to form a construct is

In Kelly's Personal Construct Theory, the concept of a construct is central to understanding how individuals interpret and predict events in their lives. According to Kelly, a construct develops through the process of comparing experiences and identifying similarities and differences. The minimum number of events needed to form a construct is three.

This is because, with three events, a person can identify a pattern that leads to a generalization. For example, if an individual has experienced three different situations where they encountered humorous responses, they can form a construct around humor that allows them to evaluate future experiences and interpret social interactions. The third event serves as a critical point that solidifies the relationship between the events and helps establish a more reliable understanding of the construct. Thus, the correct answer reflects the necessity of having three events to move beyond basic comparison into a more defined and useful cognitive framework for understanding experiences.
