SOME COMMON LOGICAL FALLACIES
AD HOMINEM ("toward the man"; attacking the person)
AD POPULUM (suggests popular opinion alone is an adequate source of validity)
APPEAL TO TRADITION (suggests tradition alone is an adequate source of validity)
BEGGING THE QUESTION (The initial point, upon which the next points are based, has not been proven.)
FALSE ANALOGY (a false comparative relationship)
FALSE EMOTIONAL APPEALS (faulty play on emotions)
FALSE USE OF AUTHORITY (false use of expertise or celebrity)
FALSE DILEMMA (limiting to "either-or")
HASTY GENERALIZATION (generalizing without sufficient grounds)
NON SEQUITUR (means "it does not follow"; the followup statement does not logically develop from the initial statement)
POST HOC…DOUBTFUL CAUSE (Post Hoc, Ergo Propter Hoc: "after this, therefore because of this")
SLIPPERY SLOPE (also known as the "Domino Theory")
STRAW MAN (attack on an easy target instead of the not difficult one under scrutiny)
