What type of fallacy might someone engage in when assuming all team members are equally skilled based on the success of a few?

The assumption that all team members are equally skilled based solely on the success of a few individuals exemplifies the composition fallacy. This fallacy occurs when one incorrectly concludes that what is true for the parts must also be true for the whole. In this case, just because a team has experienced success does not mean every member contributed equally or possesses the same level of skill and ability.

For example, a sports team might win a championship due to the outstanding performance of a couple of star players, but this does not imply that all players on the team are equally talented or that their skills contributed equally to the victory. Recognizing this fallacy is crucial in arguments related to teamwork, performance evaluations, and assessments of collective capabilities, as it helps avoid erroneous judgments about individuals based on group outcomes. Understanding this distinction allows for a more nuanced evaluation of both individual and team contributions.
