Appeal to ......

More fallacies............

Appeal to authority: when you cite another person to support your argument, while this person can be a person in authority, it is often not someone qualified to be a expert in the argument. For example:
Noted psychologist Dr. Frasier Crane recommends that you buy the EZ-Rest Hot Tub. http://www.intrepidsoftware.com/fallacy/aa.php

Appeal to tradition: supports an argument by appealing to traditional opinion, as if the past itself were a kind of authority. People have believed in God for thousands of years so God must exist. Why else would the belief last so long? www.ramdac.org

Appeal to the masses: everyone is doing it, you should too.
