{{short description|Informal fallacies based on correlative conjunctions}}
In [[Philosophy:Philosophy|philosophy]], '''correlative-based fallacies''' are [[Informal fallacy|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|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'':
{{ordered list|type=lower-alpha
|1 = Fido is a dog.
|2 = Fido is not a dog.
}}

Statements can also be mutually exclusive, without explicitly negating each other as in the following example:
{{ordered list|type=lower-alpha
|1 = Object one is larger than object two.
|2 = Object one is smaller or the same size as object two.
}}

==Fallacies==
Fallacies based on correlatives include:

;[[Philosophy:False dilemma|False dilemma]] or ''false correlative''.
:Here something which is not a correlative is treated as a correlative, excluding some other possibility.
;[[Philosophy:Denying the correlative|Denying the correlative]]
:where an attempt is made to introduce another option into a true correlative.
;[[Philosophy:Suppressed correlative|Suppressed correlative]]
:where the definitions of a correlative are changed so that one of the options includes the other, making one option impossible.
