What is the primary intent behind using a red herring in an argument?

The use of a red herring in an argument is primarily intended to divert attention from the original topic or argument. This tactic introduces an irrelevant or unrelated point that shifts the focus away from the main issue at hand. By introducing a distraction, the speaker or writer can avoid addressing the original argument's points or weaknesses, thereby steering the conversation in a different direction. The effectiveness of a red herring relies on its ability to confuse or distract the audience, making it difficult for them to engage with the original argument critically. This technique is often seen in debates or discussions where one party may want to evade scrutiny or avoid confronting tough questions, thus highlighting its intent to mislead rather than to inform or clarify.
