Logical Fallacy
As an informal fallacy, the red herring falls into a broad class of relevance fallacies. Unlike the strawman, which is premised on a distortion of the other party's position, the red herring is a seemingly plausible, though ultimately irrelevant diversionary tactic. According to the Oxford English Diction, a red herring may be intentional, or unintentional, it does not necessarily mean a conscious intent to mislead.
The expression is mainly used to assert that an argument is not relevant to the issue being discussed. For example, "I think that we should make the academic requirements stricter for students. I recommend that you support this because we are in a budget crisis and we do not want our salaries affected." The second sentence, though used to support the first sentence, does not address that topic.

Famous quotes containing the words logical and/or fallacy:
“The logical English train a scholar as they train an engineer. Oxford is Greek factory, as Wilton mills weave carpet, and Sheffield grinds steel. They know the use of a tutor, as they know the use of a horse; and they draw the greatest amount of benefit from both. The reading men are kept by hard walking, hard riding, and measured eating and drinking, at the top of their condition, and two days before the examination, do not work but lounge, ride, or run, to be fresh on the college doomsday.”
—Ralph Waldo Emerson (1803–1882)
“I’m not afraid of facts, I welcome facts but a congeries of facts is not equivalent to an idea. This is the essential fallacy of the so-called “scientific” mind. People who mistake facts for ideas are incomplete thinkers; they are gossips.”
—Cynthia Ozick (b. 1928)
