Logical fallacy, from the word itself, is a false pretense that will not give you credibility. These are baseless claims that would make irrelevant arguments. Technically, these will never work. Unless people won't recognize it.

Answer 2

Answer:

only work when people don't recognize it.

Explanation:

Logical fallacies are not actual arguments. They are flawed arguments with no real value and they only tend to work when people do not perceive what is being done. They are mostly used to attack and disrupt the contestant on a debate, to arouse an audience (if it's a provocation to the contestant, for example, a personal attack fallacy). Using fallacies might make you look really bad. Specially when people notice what you're doing.
