Which logical error occurs when attributing a soccer league's success based solely on one player from that league?

The logical error that occurs when attributing a soccer league's success based solely on one player from that league is known as Composition. This fallacy arises when one assumes that what is true for an individual member of a group is also true for the entire group. In this scenario, just because one player may be exceptionally talented and contribute significantly to the team's performance, it does not necessarily follow that this player's presence is the sole reason for the overall success of the league or that all teams in the league are equally successful because of that player.

Understanding the Composition fallacy helps to clarify that success in a league can result from a combination of factors, including the skills of multiple players, coaching strategies, and overall team dynamics, rather than being attributed to a single individual. This underscores the importance of considering the collective aspects of a group rather than deducing its qualities from an isolated case.
