Which fallacy is involved in suggesting that because an entire group is respected, one particular member also deserves respect?

The fallacy of Composition occurs when it is assumed that what is true for a group as a whole must also be true for each individual member of that group. In the context of the question, suggesting that because an entire group is respected, one particular member of that group also deserves respect is a classic example of this fallacy.

This reasoning overlooks the possibility that the individual in question may not exhibit the same qualities or characteristics that merit respect at the group level. For instance, just because a prestigious organization holds a high reputation, it does not automatically follow that every individual associated with the organization shares in that respectability or ethical standing.

Recognizing this fallacy helps to critique arguments that rely on unjustified generalizations about individuals based on their group membership.
