In philosophy, correlative-based fallacies are informal fallacies based on correlative conjunctions.
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; traditionally, terms between which this relationship exists have been called contradictories.
Examples
In the following example, statement b explicitly negates statement a:
Statements can also be mutually exclusive, without explicitly negating each other as in the following example:
Fallacies
Fallacies based on correlatives include:
;False dilemma or false correlative.
:Here something which is not a correlative is treated as a correlative, excluding some other possibility.
;Denying the correlative
:where an attempt is made to introduce another option into a true correlative.
;Suppressed correlative
:where the definitions of a correlative are changed so that one of the options includes the other, making one option impossible.
