several main groups

Generalization• Missing the point• Slippery slope• Appeal to _____• Straw man• Diversions

Rev 5/2014


28

FAULTY PREMISE• The premise is

the starting point of an argument• A premise can

be stated or assumed

Rev 5/2014

E. T. 1982


29

HASTY GENERALIZATION

• This is when people jump to a conclusion which is not supported by evidence

• This can involve stereotyping or bias

• Sam is riding her bike in her home town in Maine, minding her own business. A station wagon comes up behind her and the driver starts beeping his horn and then tries to force her off the road. As he goes by, the driver yells "get on the sidewalk where you belong!" Sam sees that the car has Ohio plates and concludes that all Ohio drivers are jerks.

Rev 5/2014


30

MISSING THE POINT• Is discussing an

issue which has nothing to do with the topic

Smoking is bad for your health. My brother, who smokes three packs of cigarettes a day, has been divorced five times. He has a terrible problem keeping committed. So smoking is bad for his marriage.

Rev 5/2014


31

APPEAL TO IGNORANCE• Since the conclusion is not conclusive, therefore it is not true

Just because no one has seen the Loch Ness Monster does not mean it doesn’t exist. So any one who doubts its existence is hasty in saying it does not exist.

Rev 5/2014


32

APPEAL TO _____• This is using someone

or something as authoritative• Authority• Common practice• Emotions• Fear• Flattery• Tradition

• "My fellow Americans...there has been some talk that the government is overstepping its bounds by allowing police to enter peoples' homes without the warrants traditionally required by the Constitution. However, these are dangerous times and dangerous times require appropriate actions. I have in my office thousands of letters from people who let me know, in no uncertain terms, that they heartily endorse the war against crime in these United States. Because of this overwhelming approval, it is evident that the police are doing the right thing."

Rev 5/2014


33

SLIPPERY SLOPE• A slippery slope is

when results are predicted that go beyond the evidence

"We've got to stop them from banning pornography. Once they start banning one form of literature, they will never stop. Next thing you know, they will be burning all the books!"

Rev 5/2014

version of the opponents opinion

• Bill and Jill are arguing about cleaning out their closets: Jill: "We should clean out the closets. They are getting a bit messy." Bill: "Why, we just went through those closets last year. Do we have to clean them out everyday?" Jill: "I never said anything about cleaning them out every day. You just want too keep all your junk forever, which is just ridiculous."

Rev 5/2014


36

DIVERSIONS• Are addressing

something else rather than the issues• Saying the same

thing twice• Giving only two

choices when there are more choices
