What are Fallacies?• Fallacies are kinds of errors in logic or problems in reasoning• They should not be persuasive, but they often are…• They may be created unintentionally, or intentionally in order to deceive people

Page 14: Fallacy Lesson

Ad Hominem “to the man”DefinitionDismisses the facts, and attacks

the person insteadHintsName callingExamplesMueller’s books on shark attacks

are worthless because he is a convicted embezzler and forger.

Page 15: Fallacy Lesson

Example

Page 16: Fallacy Lesson

Hint“To the people”Think patriotism, virtues, values, and sometimes tradition

Page 17: Fallacy Lesson

Example: Ad Populum

Page 18: Fallacy Lesson
Page 19: Fallacy Lesson

BandwagonDefinition-it’s a form of ad populum- An appeal to peer pressure and group identity

Ad Misericordiam(Appeal to Pity)

Definition: It appeals to the emotions rather than the mind of the reader- stronger appeal than ad populum

Page 27: Fallacy Lesson

Example: Appeal to PityExampleFor only pennies a day, you can save this

child’s life (insert unhealthy, unhappy picture here)

Page 28: Fallacy Lesson

Slippery SlopeDefinition an assumption that one step will inevitably lead to a second, usually undesirable step.

HintWatch for extreme assumptions

Page 30: Fallacy Lesson

DivisionDefinition: one, therefore allORIf all, therefore one

Page 31: Fallacy Lesson

Examples of Division:Examples: That high school student is so immature. All high school students are immature.

Or-All the kids from that school are stuck up, so the kid who just transferred over must be stuck up too.

Page 32: Fallacy Lesson

More• Questionable Cause: Since event B followed

event A, B must have been caused by A.• Hasty Generalization: reaching a

generalization based on insufficient evidence; without considering all of the variables• Appeal to False Authority: either the

authority is not a subject-matter expert or there is no consensus among the experts, or both

Page 33: Fallacy Lesson

How do I know if there is a fallacy here?

Is the purpose to PERSUADE?YES look for fallaciesNO probably does not contain fallacies

Is the information TRUE and verifiable?YES probably does not contain fallaciesNO text may contain fallacies

Page 34: Fallacy Lesson

Does the information contain FACTS TO BACK UP THE GENERALIZATIONS?YES probably does not contain fallaciesNO text may contain fallacies

Is the language LITERAL or FIGURATIVE?LITERAL? Text may contain fallaciesFIGURATIVE? Text probably does not contain fallacies
