FALLACY: A logical error in an argument or evaluation of a policy. The six common fallacies that surface in economic analysis are: false cause, personal attack, division, composition, false authority, and mass appeal. These fallacies are most troublesome because, although false, they seem correct, especially when used by a slick-talking, charismatic person (politician) or when the fallacies support a preconceived notion or fundamental belief.
