Which type of appeal uses humor to undermine someone’s credibility?

The correct answer is derived from the definition of an appeal that utilizes humor to discredit an opponent or their arguments. An Appeal to Ridicule is a technique where humor, mockery, or satire is employed to diminish the credibility of a person or viewpoint. This strategy aims to make an argument seem absurd or nonsensical by framing it in a humorous light, thus discouraging people from taking it seriously.

This approach can be particularly persuasive because it engages the audience emotionally, potentially leading them to dismiss the mocked position without critically analyzing the content of the argument itself. In contrast, other types of appeals have different mechanisms for persuasion or influence, such as drawing upon popular opinion, practical consequences, or a folksy, relatable tone, which do not directly rely on undermining credibility through humor.
