4 Why should we know about them?
They are EVERYWHERE: in tv and radio commercials, print ads, television shows, movies, political speeches and ads They have been used for centuries: everything from speeches in Julius Caesar to ads from the 1800’s to commercials today We can avoid logical fallacies in our own writing and detect them in the writing of others Knowledge of logical fallacies empowers us to be educated consumers in society.

5 Faulty reasoning Circular reasoning: Trying to prove a statement by repeating it in different words “Antibiotics are being overused because people take them too often.” Cause-and-effect fallacy: Falsely assuming that because one event follows another, the first event caused the second: “If we don’t make laws limiting tattoos, there will be more and more gang members.

6 Faulty reasoning Either-or fallacy: Stating that there are only two alternatives when there are many “If we don’t set limits on prescribing antibiotics, we will face worldwide epidemics caused by untreatable supermicrobes.” Bandwagon: Everyone else is doing it so why not you? “Millions of people have switched to [insert brand name here].”

7 Types of logical fallacies
Testimonial: Using a “true” story to convince the reader. “If it could happen to me…” Card stacking: Only positive information is presented, without any contradictory or negative information. Nicotine has been shown to lower incidences of Alzheimer’s disease, can boost the growth of new blood vessels, and may even reduce depression.

8 Faulty reasoning Stereotyping: creates a simplified picture of a complex situation, individual, or group. Rhetorical questions: Asks questions for which no answer is needed, to try to force the reader/listener to agree. “Are you tired of trash bags that rip and tear?”
