Assuming that something which is true of a thing must also be true of some or all of its parts (reverse of the Fallacy of Composition).


Ex. #1: “The puzzle is mostly blue. Therefore, all pieces will also be mostly blue.”

Ex. #2: “America is going to war. All Americans are proponents of this war.”
