⎜ Affirming the consequent
⎜
⎜ In propositional logic, affirming the consequent
⎜ (also known as converse error, fallacy of the converse,
⎜ or confusion of necessity and sufficiency)
⎜ is a formal fallacy (or an invalid form of argument)
⎜ that is committed when,
⎜ in the context of an indicative conditional statement,
⎜ it is stated that because the consequent is true,
⎝ therefore the antecedent is true.
