What Is Fallacy of Composition In Behavioral Economics?

The fallacy of composition is a logical error in which a conclusion is drawn about the whole based on a part. This can happen when people assume that what is true for a part of a group is also true for the whole group, without considering the unique characteristics or properties of the individual parts. For example, if you observe that a particular member of a group is skilled at a particular task, you may assume that the whole group is skilled at that task, without considering the skills or abilities of the other members. The fallacy of composition can lead to errors in judgment and decision-making, as it can cause people to make assumptions about a group based on limited or incomplete information, and to overlook important differences or variations within the group. To avoid the fallacy of composition, it is important to carefully evaluate the characteristics of each individual part of a group, and to consider the unique properties or characteristics of each part before making a conclusion about the whole group.
