Appeal to tradition
From Wikipedia, the free encyclopedia.

Appeal to tradition, also known as appeal to common practice or argumentum ad antiquitam is a very common logical fallacy in which someone proclaims his or her accuracy by noting that "this is how it's always been done." Essentially: "This is right because we've always done it this way."

The assumption behind this argument is that whatever reason led to the old methods of thinking is still valid today. If circumstances have changed, this may be a false assumption.

Examples:

"It's always been done that way. We've never done it like that."

"You're crazy! Nobody ever thought like that before!"

"This precedent was set 100 years ago and has been followed many times."

The opposite is the appeal to novelty, claiming something is good because it's new.
