concerns logical fallacies, which are errors in the logic or reasoning of an argument that result in a misconception or presumption. The fallacies tag is also appropriate for analysis of tactics that may be applied deliberately to deceive. For example, if tactical omissions in an argument motivate a member of the audience to try to fill in omitted elements, then this can be portrayed as a straw man attack against the creator of the argument.

A fallacy is incorrect argument in logic and rhetoric resulting in a lack of validity, or more generally, a lack of soundness. Fallacies are either formal fallacies or informal fallacies.
