1 Bellwork Friday November 18th In your Writing Journal please respond to the following prompt: What is the most ridiculous argument you have heard? Remember this is NOT fight argument. I m talking trying to convince someone of a point argument. Describe the argument and what about it made it so ridiculous and/or ineffective. If you are not writing when I walk in, you are late. Do NOT stop writing until I tell you to.

2 Fallacious Reasoning What NOT to do in an argument

3 Fallacious what? Fallacious Adjective Based on mistaken belief Any argument that is based on faulty thinking or incorrect evidence An argument that is desperately lacking why proof-ness

4 What are logical fallacies? flaws in reasoning that lead to faulty, illogical statements. Unreasonable persuasive tactics (named for what has gone wrong during the reasoning process. )

5 Ad Hominem Making it Personal An attack on the person proposing an argument rather than on the argument itself. Example- -Sara is divorced, so whatever relationship advice she gives you can t be good. Senator Jones was a conscientious objector during the Vietnam War, so his proposal to limit military spending has no merit.

6 Circular Reasoning Any statement that assumes what you are trying to prove is true has no evidence is a because statement

7 Circular Reasoning- Examples I m in charge. Why? Because I said so. I am late because I m always late.

23 Over-Generalization The first two people I saw at Comic Con with Dr. Who shirts on were short. Whovians must be all be short. Mr. Gildea likes brownies and he is a teacher. All teachers must like brownies.

26 Hasty Generalization A statement that is based on an inference on too SMALL a sample uses one example to explain a much broader topic

28 Hasty Generalization Laura dated a guy with blond hair last year, she must only like blonds. Ashton s car is black, that must be his favorate color.

29 False Dichotomy (either or fallacy) the arguer sets up the situation so it looks like there are only two choices. The arguer then eliminates one of the choices, so it seems that we are left with only one option: the one the arguer wanted us to pick in the first place. Example- "Caldwell Hall is in bad shape. Either we tear it down and put up a new building, or we continue to risk students' safety. Obviously we shouldn't risk anyone's safety, so we must tear the building down."

30 **Post Hoc** (This one is everywhere in politics) Short for post hoc, ergo propter hoc, which means after this, therefore caused by this.this fallacy assumes that just because B happened after A, it must have been caused by A. Example- Since Governor Bush took office, unemployment of minorities in the state has decreased by seven percent. Governor Bush should be applauded for reducing unemployment among minorities.

31 False Analogy Example-

32 Non Sequitur (Does not follow)

33 Straw Man This move oversimplifies an opponent's viewpoint and then attacks that hollow argument. Example- People who don't support the proposed state minimum wage increase hate the poor.

34 Red Herring This is a diversionary tactic that avoids the key issues, often by avoiding opposing arguments rather than addressing them. Example- The level of mercury in seafood may be unsafe, but what will fishers do to support their families?

35 Slippery Slope a person asserts that some event must inevitably follow from another without any argument for the inevitability of the event in question. The outcome stated tends to be extreme and dramatic

36 Slippery Slope Because mom was late getting home the dinner wasn t ready so I knew I would starve to death. There is Ebola in Dallas. America is going to die.
