A fallacy is an argument that seems valid but fails logic

Evidence

Fallacies are dangerous because they are false conclusions or interpretations resulting from thinking processes that claim or appear to be valid, but fail to conform to the requirements of logic.8 A fallacy can, therefore, be defined as “any argument that seems conclusive to the normal mind but that proves, upon examination, not to establish the alleged conclusion,”9 or more succinctly, a form of argument that seems to be correct but that proves upon examination not to be so. — Ruggero J.
