Final answer:
A red herring is a distraction from the main issue and falls under fallacies of diversion, where one shifts focus to a tangentially related subject instead of addressing the original argument.
Step-by-step explanation:
The term red herring refers to a distraction from the main issue. Specifically, it's a logical strategy where someone introduces an irrelevant topic in order to divert attention away from the original argument. The red herring fallacy resembles the strawman fallacy but involves completely ignoring the opponent's position and shifting the focus to a tangentially related subject. This tactic falls under fallacies of diversion, a class of informal fallacies where the arguer seeks to distract the audience or opponent.
For example, if someone argues that a family should have more nutritious meals and the counterargument focuses on the difficulty of finding organic food stores, the latter is a red herring because it shifts away from the overall goal of nutrition to the specific challenge of sourcing organic foods.
