logical fallacy definition
For specific popular misconceptions, see List of common misconceptions. A fallacy is an incorrect argument in logic and rhetoric which undermines an argument's logical validity or more generally an argument's logical soundness. Fallacies are either formal fallacies or informal fallacies. These are commonly used styles of argument in convincing people, where the focus is on communication and results rather than the correctness of the logic, and may be used whether the point being advanced is correct or not.
