How does the fallacy of composition wrongly transfer a property of parts to a whole?

The fallacy of composition occurs when one incorrectly assumes that a property inherent to the individual parts of a whole must also apply to the collective whole itself. This error arises from a confusion between the distributive use of a term—applying to the elements of an aggregate—and its collective use, where the term refers to the group as a unitary entity.1

For example, one might argue that because every paragraph in a story is well-written, the story as a whole must be good. This reasoning is flawed because the quality of individual components does not automatically guarantee the quality of the entire structure. Similarly, this fallacy often involves assuming that what is true for each member of a class will be true for all of them together.12

This type of error is closely related to equivocation, as it relies on shifting the meaning of a term between its individual and collective applications. It is the logical inverse of the fallacy of division, which wrongly assumes that properties of a whole must necessarily belong to its parts.1
