Appeal to common sense
Also called: Everybody knows
Treating something as obvious so it doesn't need an argument.

Is “it's just common sense” offered in place of reasons?
Example
“It's obvious. Anyone can see it.”
How to answer it
Many true things aren't obvious, and some obvious things are false. Ask why.
