The Fallacy of Composition
The Stereotype Fallacy
The Fallacy of Composition, a Fallacy of Ambiguity, exists when the fallacious assumption that, because all of the parts of something have a unified property, the sum of those parts will also have that same property.
The opposite of this fallacy is the Fallacy of Division.
Example: Every piece of equipment in Mr. Spagnolo's backcountry backpack is ultra-lightweight; therefore, the total weight of his backpack when full is ultra-lightweight.
Actually, it's heavy. 23 kilos of ultra-lightweight material weighs the same as 23 kilos of bricks.
Example: Bob is made up of atoms. Atoms can't be seen. Therefore, the Bob is invisible.
Bob is right there. *points to Bob* He's made up of atoms AND he's visible.
Example: An individual would never, alone, stampede into and try to take over the U.S. Capitol. A group is a collection of individuals. Therefore, a large group would never attempt to stampede into and try to take over the U.S. Capitol.
We know the last portion of this point is illogical because we've seen it happen!
