Biased arguments
Biased Arguments

  • A fallacy is an error in logical thought.

    • Thomas Edison invented the light bulb. (Unbiased statement)

    • Lashonda trusts the news story because it’s printed in the newspaper. (biased argument)


What is propaganda
What is Propaganda?

  • Propaganda is an act of persuasion that systematically spreads biased information that is designed to support or oppose a person, product, cause, or organization.

  • Emotional appeal is the arousal of emotions to give a biased meaning or power to an idea.

    • Spicy foods and stress cause stomach ulcers. (unbiased statement)

    • Don’t buy your insurance from DealState; that outfit is a bunch of crooks. (biased argument)


Irrelevant arguments fallacies
Irrelevant Arguments: Fallacies

  • Personal attack is the use of abusive remarks in place of evidence for a point or argument. Also known as an ad hominem attack, it attempts to discredit the point by discrediting the person making the point.

  • Example: Sam, a convicted felon, wants to ban smoking in restaurants. His opponents attack his criminal record, not his idea: “Now the lawbreakers want to make the laws.”

Irrelevant Arguments: Fallacies

  • A Straw Man fallacy is a weak argument substituted for a stronger one to make the argument easier to challenge.

  • It distorts, misrepresents, or falsifies an opponent’s position. Attention is shifted away from a strong argument to a weaker one.

  • Example:Governor Goodfeeling opposes drilling for oil in Alaska. But the U.S. is too dependent on foreign oil supplies, and the economy would benefit from having an American supply for oil. The Governor wants to keep us dependent on foreign oil cartels.

The governor’s reasons for opposing drilling are not mentioned. Instead, the writer changes the tactic to the U.S. dependence on oil.

Irrelevant Arguments: Fallacies

  • Begging the question restates the point of an argument as the support and conclusion. It is also known as circular reasoning.

  • Example: “Spinach is an awful tasting food because it tastes bad.” (BQ)

  • Example: “I never eat spinach because it has a bitter taste, and I don’t like foods that taste bitter.” (not BQ)


Irrelevant arguments propaganda techniques
Irrelevant Arguments: Propaganda Techniques

  • Name-calling uses negative labels for a product, idea, or cause. The labels use emotionally loaded words and use details that cannot be verified.

  • Examples:

    • Cristina Singer has an air of raunchy diva in her newest album. Even though her voice delivers a decent mix of pop, rock and soul, her vampire-in-leather costume and wicked-witch makeup makes her act scary to watch.

    • People who burn the flag are traitors.


Irrelevant arguments propaganda techniques1
Irrelevant Arguments: Propaganda Techniques

  • Testimonials are irrelevant personal opinions to support a product, idea, or cause. Often a celebrity is used as a spokesperson.

  • Example: Famous athlete Jerome High-Jumper says, “Drinking milk every day makes me the athlete I am.”

  • Bandwagon uses or suggests the irrelevant detail that “everyone is doing it.” Therefore, you should do it too!

  • Example: “I should be able to stay out until 3 A.M. All the other kids can. I’m the only one who isn’t allowed to stay out late on prom night.”


Irrelevant arguments propaganda techniques3

  • Plain folks uses irrelevant details to build trust based on commonly shared values. An image is put forth to which everyday people can more easily relate.

    • A candidate running for office dressed in blue jeans and a plaid shirt eating a hotdog.

    • A woman dressed in casual clothes cooking in a kitchen where the TV ad is trying to get you to buy their product.


Inadequate arguments fallacies
Inadequate Arguments: Fallacies

  • Either-or assumes that only two sides to an issue exist. Also known as the black-and-white fallacy, it offers a false dilemma because more than two options are usually available.

  • Example: “If you don’t give to the toy drive, you don’t care about children.”
