Rhetorical QuestionsA question posed for its persuasive effect.Not supposed to be answered.Ex: "Aren't you glad you use Dial?Don't you wish everybody did?"

Bandwagon Persuasive technique that invites you to join the crowd with the argument that everyone else is doing it.Everybodys doing it!If many people believe it, it must be so.

Everyone in Auburn is supporting Bob Riley. Shouldnt you be part of the winning team?

5As a propaganda technique, the term bandwagon suggests an imaginary vechicle carrying leaders or candidates of a cause or carrying large banners and/or posters. This group has a huge group of people following behind and all are in support of that leader/candidate. A bandwagon is a high, ornate wagon in which a band rides as in a circus parade.Unfortunately, most of us like to swim with the sharks rather than stand alone, so we are likely to be carried along. Beware of this technique. Its a lot easier to be joiner than to stand alone.

Bandwagon is a propaganda technique that suggests an image of a vechicle carrying a leader/candidate Loaded Words Using language with emotional connotations to further an argument.Descriptive words used to elicit strong feelings.ExamplesHouse shackJob choreDog muttPerfume - odorTestimonialStatement endorsing an idea/product by a prominent person celebrity, politician, radio personality, etc.Product does not have to be related to stars field.Commonly uses musical artists, sports giants, actors/actresses

Calling herself "an average hockey mom," Palin joked, "You know what they say the difference is between a hockey mom and a pit bull? Lipstick!

Snob AppealAssociating a product or decision with the idea that it will raise us above the common folks.

Misuse of StatisticsUsing statistics to change your audiences in opinions in your favor.ExampleChildren with bigger feet spell better.This was the result of a survey about measuring factors affecting the spelling ability of children. When the final analysis came about, it was noted that children with bigger feet possessed superior spelling skills! Upon further analysis you will find that older children had bigger feet and quite certainly, older children would normally possess better spellings than their younger counterparts!

Name - CallingThe use of language to demean or degrade the other side of the argument.Used a lot by politicians or towards politicians.

My opponent is a flip-flop man who cannot make up his mind. He changes mind with the breeze! How could anyone follow such a weak-willed flip-flopper?

Logical FallaciesPersonal AttackAn argument which states that a person is wrong based on their characteristics.

Examples"You're new here, aren't you?"I used to think that way when I was your age."False AnalogyFinding similarity where none existsExample:Chilies are spicyChilies are red.Red things are spicy.

Democrats choose Nancy Pelosi.Gas prices are up 39%.Nancy Pelosi and the Democrats are responsible for the gas prices.False DilemmaWhen only two choices are given.Example:America, love it or leave it.

You do not always have to love America to live here.

Appeal to FearPersuasion through fear or forceExamples"You know, Professor Smith, I really need to get an A in this class. I'd like to stop by during your office hours later to discuss my grade. I'll be in your building anyways, visiting my father. He's your dean, by the way. I'll see you later." You must believe that God exists. After all, if you do not accept the existence of God, then you will face the horrors of hell."
