Appeal to emotion
Appeal to emotion or argumentum ad passiones (meaning the same in Latin) is an informal fallacy characterized by the manipulation of the recipient's emotions in order to win an argument, especially in the absence of factual evidence.[1] This kind of appeal to emotion is irrelevant to or distracting from the facts of the argument (a so-called "red herring") and encompasses several logical fallacies, including appeal to consequences, appeal to fear, appeal to flattery, appeal to pity, appeal to ridicule, appeal to spite, and wishful thinking.
Appeal to emotion is an application of social psychology. It is only fallacious when the emotions that are elicited are irrelevant to evaluating the truth of the conclusion and serve to distract from rational consideration of relevant premises or information. For instance, if a student says "If I get a failing grade for this paper I will lose my scholarship. It's not plagiarized." the emotions elicited by the first statement are not relevant to establishing whether the paper was plagiarized. Also, the statement "Look at the suffering children. We must do more for refugees." is fallacious, because the suffering of the children and our emotional perception of the badness of suffering is not relevant to the conclusion (to be sure, the proper role, if any, for emotion in moral reasoning is a contested issue in ethics).
Appeals to emotion are intended to cause the recipient of the information to experience feelings such as fear, pity, or joy, with the end goal of convincing the person that the statements being presented by the fallacious argument are true or false, respectively.
