False Logic is the name the Detecting Patterns of Deception page gives to errors in reasoning that invite us to accept a false premise or conclusion. The Unwarranted Causal Inference known as post hoc ergo propter hoc confuses coincidence with cause. Conspiracy Theorizing makes unwarranted inferences from shifting premises. Those who offer a Slippery Slope argument make an unjustified inference about the inevitable effects of an indicted action. False Choice misframes a decision by excluding viable options. Shifting Denominator changes the basis for an inference from the one assumed by the audience without flagging the change. Guilt by Association (which can be seen as a form of ad hominem) invites inferences from unjustified comparisons between the attacked person and someone or something disreputable. Insinuation works by negative implication to get audiences to accept a premise that has not been justified by offered evidence.
