An appeal to common sense is a logical fallacy that occurs when something is claimed to be true because (according to the speaker) it is "common sense" or "obvious" that the claim is true. It is a form of or similar to an Argument from incredulity.

It is an emotional appeal and an informal fallacy.

Form[edit]

P1: X is obvious.

P2: (unstated) Anything obvious is true

C: X is true

Examples[edit]

"It's obvious that the world must have a creator!" or "Obviously, just like a watch has a maker, the world does!"

(Argument from incredulity) "It's obvious the world has no creator!" (which is the opposite of the above example)

"It's obvious that the Earth is flat!"

Problems[edit]

Different people have different and sometimes contradictory "common sense"; there is no universal common sense. Even if everybody alive agreed something is common sense, it wouldn't automatically be true.
