  1. Persuasive Techniques: A Look at Logical Fallacies Created by Jenny Langer Spring 2008 EDTEC 470, SDSU

  2. What is Persuasion? • It is the process of gliding people toward the adoption of an idea, action or attitude • Often it is illogical and manipulative • Thirsty?

  3. Let’s Break it Down… • The purpose of persuasion is to convince someone of your point of view. • But how do we do that? • Good Question!

  4. Logical Fallacy Logical = something that is reasonable, (it makes sense) Fallacy = something that is faulty, (a mistake) So… Logical + Fallacy = A Mistake in Reasoning

  5. “Hey, Why are We Learning How to Reason Incorrectly?” Another good question! It’s called logical self-defense. Do you believe everything you read, hear and see? ►

  6. Keep in Mind… You cannot always believe what you hear, what you see, and what you read. Advertisements, movies, commercials, politicians, critics and spokespeople have an agenda in mind as well.

  7. A Bandwagon Fallacy • The name comes from the phrase, "jump on the bandwagon“, a bandwagon being a wagon big enough to hold a band of musicians. In past political campaigns, candidates would ride a bandwagon through town, and people would show support for the candidate by climbing aboard the wagon. • It has come to mean joining a cause because of its popularity. • If it’s popular, it must be correct!

  8. Lets look at an example of Bandwagon • Turn to your neighbor and discuss why this advertisement is an example of Bandwagon • Then as a class we will share our ideas • Hint: Who is that guy?

  9. Red Herring Fallacy • The name comes from the sport of fox hunting in which a dried, smoked herring, which is red in color, is dragged across the trail of the fox to throw the hounds off the scent. • Logical maybe…but unrelated • The argument given uses distraction to avoid the issue

  10. Be Creative!! • With your partner, try writing a slogan or drawing an advertisement that uses a Red Herring Fallacy. • Here are some ideas you can use: -Increasing the school year to more than 180 days -Serving Krispy Kreme Doughnuts at school *Remember you are trying to convince someone of your view by distracting them using something unrelated.

  11. Emotional Appeal • This term refers to manipulating someone by targeting their emotions and feelings. • For example, the ad can make viewers feel happy, sad, nostalgic, fearful, angry etc… • Buying something will make them feel better.

  12. Ad Hominem “Against the Man” In order to prove your point, you make a personal attack on your opponent or opposing side "She has never run anything. And the idea that she could learn to be President as an internship just doesn't make any sense. I've spent my life running things, I've learned how to run a business.” -Quote from former presidential hopeful, Sen. Mitt Romney attacking Sen. Hillary Clinton

  13. Using Ad Hominem, One Might Argue… “You should buy a Macintosh. They are so much better than PC’s. Besides, Bill Gates is an idiot. Microsoft isn’t so great anyway.”

  14. With Your Partner Examine the ad I am about to show you. Which type of fallacy do you think Coca-Cola is using? And why? In about 10 minutes, we will share our ideas as a class. And Here it is…

  15. More Ads for Fun!
