5. 1.Red herring: A campus speech code is essential to protect students, who already have enough problems coping with rising tuition. [Tuition costs and speech codes are different subjects. What protection do students need that a speech code will provide?] 2.False authority: Jason Bing, a recognized expert in corporate finance, maintains that pharmaceutical companies do not test their products thoroughly enough. [Bing’s expertise in corporate finance bears no apparent relation to the testing of pharmaceuticals.] 3.Snob appeal: Tiger Woods has an account at Big City Bank, and so should you. [A celebrity’s endorsement does not guarantee the worth of a product, a service, an idea, or anything else.] Source: The Little Brown Handbook, 11th ed

[Stereotyping] 8.Hasty generalization: Several youth who shot up schools were users of violent video games. Obviously, these games can breed violence and they should be banned. [Jumping to conclusions] Source: The Little Brown Handbook, 11th ed

7. 9.Reductive fallacy: Poverty causes crime. [If so, then why do people who are not poor commit crimes? And why aren’t all poor people criminals?] 10.Post hoc fallacy: In the two months since he took office, Mayor Holcomb has allowed crime in the city to increase 12 percent. [The increase in crime is probably attributable to conditions existing before Holcomb took office.] 11.Either/or fallacy: City police officers are either brutal or corrupt. [Most city police officers are neither.] 12.Circular Argument: Dr. Martin Luther King, Jr. was a good communicator because he spoke effectively. Source: The Little Brown Handbook, 11th ed
