A logical fallacy is an error in reasoning based on a mistaken belief or false idea usually with the intent of shifting the focus away from the primary issue.  Logical fallacies weaken arguments, inhibit discussion, and misrepresent ideas.  The ability to identify and avoid using logical fallacies yourself as well as counter those used by other people helps to keep discussions focused and limits the introduction of extraneous or unrelated topics.  As an educational leader, you interact with people numerous ways; being aware of the pitfalls of engaging in logical fallacies and being able to avoid them will help ensure your interactions are fair, rational, and objective.
