A straw man fallacy (sometimes written as strawman) is the informal fallacy of refuting an argument different from the one actually under discussion, while not recognizing or acknowledging the distinction.[1]One who engages in this fallacy is said to be "attacking a straw man".

The typical straw man argument creates the illusion of having refuted or defeated an opponent's proposition through the covert replacement of it with a different proposition (i.e., "stand up a straw man") and the subsequent refutation of that false argument ("knock down a straw man") instead of the opponent's proposition.[2][3] Straw man arguments have been used throughout history in polemical debate, particularly regarding highly charged emotional subjects.[4]
