Correlative based fallacies are logical fallacies based on correlative conjunctions. A correlative conjunction is a relationship between two statements where one must be false and the other true. In formal logic this is known as the exclusive or relationship. Examples of correlatives are:

A: Object one is larger than object two. B: Object one is smaller or the same size as object two.

A: Fido is a dog. B: Fido is not a dog.

Fallacies based on correlatives are:

The false dilemma or false correlative. Here something which is not a correlative is treated as a correlative, excluding some other valid possibility.

The fallacy of denying the correlative, where an attempt is made to introduce some other invalid option into what is a true correlative.

The fallacy of suppressed correlative, where the definitions of a correlative are changed so that one of the options includes the other, making one option impossible.
