1 Fallacies

2 What is wrong with the following sentences? 1.I love Disneyland because I’m always happy there. 2.Everyone on the team wears Nike shoes; it’s the only way to go! 3.I love music, therefore I love the Jonas Brothers.

3 Objective To understand what makes a logical fallacy, how to catch someone when they are using one (perhaps to pull a fast-one on you), and how to avoid using them in your own writing and dialogue.

4 Logical Fallacy A logical fallacy is a statement that contains faulty reasoning. Don’t give your reader a reason to doubt your information. Persuasive writing especially requires sound logic to support opinions.

5 Circular Reasoning Supporting a statement by simply repeating it in different words. Teens should avoid fad diets, because it is important for adolescents to stay away from weight-loss plans.

6 Either / Or Fallacy A statement that suggests that there are only 2 choices available in a situation that really offers more than 2 options. Either students should be allowed to go off campus for lunch to Burger King, or they should choose from the cafeteria’s food.

7 Oversimplification An explanation of a complex situation or problem as if it were much simpler than it is. Making the team depends on whether the coach likes you. http://www.youtube.com/watch?v=Snp qG3h6pY8 http://www.youtube.com/watch?v=Snp qG3h6pY8

8 Overgeneralization A broad generalization. No one cares about the story. A little kid might say: “All birds can fly.”

9 Stereotyping A dangerous type of overgeneralization. All girls can’t play sports. All boys lie and cheat. http://www.youtube.com/watch?v=_ktg Bpdy99c http://www.youtube.com/watch?v=_ktg Bpdy99c

10 Attacking the person or name- calling (poisoning the well) An attempt to discredit an idea by attacking the person or group associated with it. My opponent is not smart enough to be mayor. She is basic. http://www.youtube.com/watch?v=Ug7 5diEyiA0&list=PL2Rf1R6EcGZTov9OQU WpwaA7xczA7cXRF http://www.youtube.com/watch?v=Ug7 5diEyiA0&list=PL2Rf1R6EcGZTov9OQU WpwaA7xczA7cXRF

11 Evading the Issue Refuting an objection with arguments and evidence that do not address its central point. Yes, I broke my promise to not raise taxes, but taxes have paid for your new highways. I know I am late, but you look beautiful. What you do with your parents when you are in trouble!

12 Non sequitur (post hoc) A statement that uses irrelevant proof to support a claim. I know I’ll pass math. Mr. Gray is my math teacher and my football coach. http://www.youtube.com/watch?v=vRJ UvFG8gbE http://www.youtube.com/watch?v=vRJ UvFG8gbE

13 False Cause The mistake of assuming that because one event occurred after another event in time, the first event caused the second to occur. I failed English because of football. http://www.youtube.com/watch?v=MTb ZoKEOkUg http://www.youtube.com/watch?v=MTb ZoKEOkUg

14 False Analogy A comparison that doesn’t hold up because of a critical difference between the two subjects. She walks to school and back every day, so surely she can walk in a 10K race. http://www.youtube.com/watch?v=60N SO9pJyVI http://www.youtube.com/watch?v=60N SO9pJyVI

15 Hasty Generalization A conclusion drawn from too little evidence or from evidence that is biased. That corner must be dangerous. There were two car accidents there last week.

16 Bandwagon Appeal Uses the argument that a person should believe or do something because “everyone else” does. The Cardinals are a winning team and everyone likes them so you should to. http://www.youtube.com/watch?v=vGL Hlvb8skQ&list=PL4CC0F6415CD51AC4 http://www.youtube.com/watch?v=vGL Hlvb8skQ&list=PL4CC0F6415CD51AC4

17 Testimonial Relies on endorsements from well-known people or celebrities. Proactive-Jessica Simpson Gatorade-Michael Jordan http://www.youtube.com/watch?v=gq_ EZjhHaDY http://www.youtube.com/watch?v=gq_ EZjhHaDY

18 Snob Appeal Taps into people’s desire to be special or be part of an elite group. Treat yourself to a tropical paradise because you deserve the best. http://www.youtube.com/watch?v=JAB V8Sez45s http://www.youtube.com/watch?v=JAB V8Sez45s

19 Transfer Connects a product, candidate, or cause with a positive emotion or idea. Freedom…you can feel it the instant you put your hands on the new Jeep Wrangler. http://www.youtube.com/watch?v=R55e -uHQna0 http://www.youtube.com/watch?v=R55e -uHQna0

20 Appeal to Loyalty Relies on people’s affiliation with a particular group This car is made in America by Americans. http://www.youtube.com/watch?v=5Wa _6g9WNgU http://www.youtube.com/watch?v=5Wa _6g9WNgU

21 Appeals to pity, fear, or vanity Use strong feelings rather than facts to persuade. Without more police, we will be at the mercy of thieves. http://www.youtube.com/watch?v=92kP KbXHqss http://www.youtube.com/watch?v=92kP KbXHqss

22 Glittering Generality Makes a generalization that includes a word or phrase with positive connotations (feelings) to promote a product or idea. A vote for Tom Jones is a vote for democracy! http://www.youtube.com/watch?v=J2Cz5dZOtAc
