1. Faulty Reasoning What’s wrong with this statement?
We are taking notes in our Writer’s section. Date your notes.

2. What is faulty reasoning/logic?
Faulty = having faults, imperfect
Faulty reasoning would be flawed or imperfect
This is another kind of persuasive technique

3. Where do we see faulty logic used?
In newspaper editorials
In commercials
Print ads
Conversations
Books
Magazines

4. Why do we have to learn about it?
Part of being a savvy consumer is being a skeptical consumer.
Learning to recognize faulty logic is the first step in avoiding it.

5. Hasty Generalization
DEFINITION: drawing a conclusion based on a very small sample size or small set of evidence, rather than looking at what may be more in line with the typical/ average situation
EXAMPLE: My father smoked four packs of cigarettes a day since age fourteen and lived until age seventy-nine. Therefore, smoking can’t really be that bad for you.
EXPLANATION: You can’t draw a conclusion on the dangers of smoking based of off one personal experience.

6. 1. Circular Reasoning
DEFINITION: the writer (or speaker, or ad) supports a claim with restatements of that same claim. The argument goes around and around with the reason making the same claim as the original argument.
EXAMPLE: John Updike is a wonderful writer because he writes so well.
EXPLANATION: The second half of the statement says basically the same thing as the first half.

7. Strategy for Circular reasoning
Circular Reasoning Look at sentence beginnings and endings.
If the faulty logic is circular reasoning, the ending will be almost the same or, at least, very similar to the beginning.

8. 2. Overgeneralization
DEFINITION: The writer reaches conclusions from a limited number of facts. (Look for words such as all, every, and always.)
EXAMPLE: “I loved that movie we saw last night with Brad Pitt. I am going to rent all of his movies, and I am sure I’ll like all of them.”
EXPLANATION: It is an imperfect judgment (or faulty logic!) to assume that you will love all Brad Pitt movies just because you loved one!

9. Strategy for Overgeneralization
Overgeneralization Look for context clues: all, every, always, never.
Stereotypes may also be present.

10. 3. Self- contradiction
DEFINITION: The writer states a position that contradicts an earlier stated premise.
EXAMPLE:As Mayor, my top priority will be improving education. So my first act of office will be to cut funding for our public schools.
EXPLANATION: Cutting public school funding contradicts the mayor’s first statement that improving education will be his top priority.

11. Strategy
Self-Contradiction Look at sentence beginnings and sentence endings.
The beginning and ending will be opposites—they will contradict each other.

12. 4. False Causality (False Cause)
DEFINITION: This occurs when two events happen at the same time, and an assumption is made that one event causes the other.
EXAMPLE: Our house was burglarized right after that new family moved in next door.
EXPLANATION: This statement attributes a false cause(new family next door) to the effect (the burglary).

13. Strategy False Causality Look for a cause and effect relationship.
There may not be enough proof/evidence to support that one thing caused the other. Correlation does not equal causation.

14. 5. Over-simplification
DEFINITION: This occurs when a single cause is assumed to have created a problem or an issue. In reality, the problem or issue may have been created by a number of causes.
EXAMPLE: The cause of the Civil War was slavery.
EXPLANATION: The above statement is too simplistic. Slavery was only one of several reasons the Civil War was fought.

15. Strategy Look for a cause and effect relationship in the statement.
The causes have been cut down to ONE CAUSE.
The ONE CAUSE is TOO SIMPLE!

16. 6. Assumptions
DEFINITION: This occurs when the writer may be proven false or may be merely stating an opinion.
EXAMPLE: The Superstition Mountains are the most beautiful mountains in Arizona.
EXPLANATION: Yes, these mountains are beautiful, but that is only one man’s opinion. Others may think another mountain range in Arizona is more beautiful.

17. Strategy
Assumptions Ask these questions: Does this statement involve a stereotype?
Is this statement just an opinion?
Can this statement be proven false?
If the answer is yes to any of these questions, then the faulty logic is probably an assumption.

18. Practice Number 1- 5 in your notebook
You will see six statements. For each, write in your notebook which kind of faulty reasoning is at work.

19. 1. What type of faulty logic is the following statement?
STATEMENT:I argued with Ms. Chambers before I turned in my homework so I got a bad grade on my paper.

20. 1. THE ANSWER: False Causality
WHY? The student suggests that because he/she argued with his/her literacy teacher prior to turning in a paper (cause), the result/effect was a bad grade.
STRATEGY: Try to identify an end result or effect. Ask yourself: Did the reason given really cause the end result?

21. 2. What is the faulty logic in the following statement?
STATEMENT: I hated the movie because it was the worst movie I ever saw.

22. 2. THE ANSWER: Circular Reasoning
WHY?“…the worst movie I ever saw” is basically the same thing as “I hated the movie.” It’s saying the same thing.
STRATEGY: Look at the end of the sentence. Is it really similar to the beginning? Is it going around and around?

23. 3. What is the faulty logic here?
STATEMENT: All football players are poor students.

24. 3. THE ANSWER: Overgeneralization
WHY? This statement takes in an entire group of people all at once. It may be that some football players are poor students, but it is unfair to suggest that is true of all football players.
STRATEGY: Remember! Look for words like all, every, and always.

25. 4.
What is this one?
STATEMENT: I know why you failed all your classes last semester. You don’t study.

26. 4. THE ANSWER: Oversimplification
WHY? There could be many reasons why a student experiences difficulty in school. Reducing the problem to one solution is oversimplifying.
STRATEGY: Look for an effect that has MANY possible causes.

27. 5.
And this one?
STATEMENT: The first rule is that there are no rules.

28. 5. THE ANSWER: Self-Contradiction
WHY :If there are no rules, there can be no first rule!
STRATEGY: Look at the beginning of the sentence; look at the end. Are they the opposite of each other?
