Fallacies of Context:
Composition

The fallacy of composition occurs when we assume that what is true of a part must be true of the whole. Of course, parts and wholes do sometimes have the same properties, but we commit the fallacy of composition when we jump to a conclusion about the whole without taking into account whether the nature of the property in question makes it reasonable.

For example, consider my car radio, which is manufactured by Motorola. It would be a fallacy of composition to infer that my car as a whole was made by Motorola, just because one part was.


False alternative | Post hoc |
Hasty generalization | Composition | Division
