common rhetorical fallacies

The following are a few of the more common fallacies used in argument. A fallacy occurs when there is faulty reasoning, or when something is intrinsically wrong with the argument being made. Fallacies are all around us! Along with conveying an understanding of these techniques in your rhetorical analysis essay, look for them in commercials or advertisements and question how (and why) they attempt to manipulate the consumer.



ethical fallacies
  • Ad hominem (to the man): a character attack, insulting a person or cause instead of addressing the argument or issue. Example: political debates.
  • Guilty association: attacking the company that a person keeps in an attempt to discredit them or render them “guilty.” Making assumptions about a person’s character based on outside influences. Example: Salem witch trials.
logical fallacies
  • Begging the question: a cyclical argument that is based on an assumption made by the writer. A statement made that depends on an assumption that hasn’t been proved yet. Example: 60 minutes claims that it is the best news show on television.
  • Post hoc (doubtful cause): assuming that two events are related, that one is the cause for the other when it could just be coincidence. Example: Since the rooster crows and then the sun rises, the rooster causes the sunrise.
  • Non sequitur (it does not follow): a fallacy of irrelevance. Two unrelated ideas are linked together. Example: Since Toho Production Company is still making Godzilla movies in the year 2000, Japan should host the Olympic games again in 2004.
  • Either-Or (false dilemma): when an argument assumes that a complex situation can have only two possible outcomes. Example: Adrienne Rich’s essay claimed that a woman today could either be a victim or a token professional, nothing in between.
  • Hasty generalization: utilizing stereotypes in an argument, making sweeping conclusions based on little evidence. Example: Understanding that Lori likes cats, all girls prefer feline pets to canine pets.
  • Oversimplification: careless reasoning that doesn’t factor in all of the issues at hand. Example: The United States could easily balance its budget if it weren’t for exorbitant defense spending.
  • Slippery Slope: an assumption that one step will inevitably lead to a second, usually undesirable step. A simplistic argument that makes an improbable prediction. Example: The Connecticut law allowing children to divorce their parents will mean the death of the family unit.
  • Straw Man (diversion): a diversionary tactic to draw attention away from the argument. Example: When asked if he had sexual relations with Miss Lewinsky, the president stated that he was an honorable man.
emotional fallacies
  • Bandwagon: everyone else is doing it! Example: McDonalds: 100 billion served.
  • Flattery: sweet talk and persuasive language. Example: For discriminating tastes…
  • In-crowd appeal: if you adopt certain behavior or beliefs, then you will be in the cool crowd. Example: GAP commercials, most clothing ads, Marine commercials, cigarette ads, etc.
  • Veiled threat: adverse consequences will occur if this action is not taken, or if this argument is not believed. Example: Brita water filters protect you from harmful contaminants and chemicals.
  • False analogy: assuming without sufficient proof that if two things are similar in some ways, they will be similar in other ways, as well. Example: Since human life has only existed for approximately 100,000 years, and many other species that have existed for even longer are now extinct, man will one day become extinct.
  • Weasle words and qualifyers: see essay, “With These Words I Can Sell You Anything.” Words, phrases, and terms that are either meaningless or misleading. Example: New and Improved!
