List 1: Fallacies Flashcards
Slippery Slope
This logical fallacy is the argument that a position is not consistent or tenable because accepting the position means that the extreme of the position must also be accepted.
EX:”If we legalize marijuana, then more people will try heroin.”

Straw Man
“Fallacy of Extension” A straw man argument attempts to counter a position by attacking a different position – usually one that is easier to counter. The arguer invents a caricature of his opponent’s position – a “straw man” – that is easily refuted, but not the position that his opponent actually holds.
EX: Mr. Marshall cuts money from band
Counter: Why doesn’t Mr. Marshall care about band?

Red Herring
“Changing the Subject” A Red Herring is a fallacy in which an irrelevant topic is presented in order to divert attention from the original issue. The basic idea is to “win” an argument by leading attention away from the argument and to another topic. This sort of “reasoning” has the following form:
Topic A is under discussion.
Topic B is introduced under the guise of being relevant to topic A (when topic B is actually not relevant to topic A).
Topic A is abandoned.
This sort of “reasoning” is fallacious because merely changing the topic of discussion hardly counts as an argument against a claim.
EX: Students should take four years of math because the math classes are pretty empty. (not relevant)

Hasty Generalization
This fallacy is committed when a person draws a conclusion about a population based on a sample that is not large enough. It has the following form: Sample S, which is too small, is taken from population P.
Conclusion C is drawn about Population P based on S. The person committing the fallacy is misusing the following type of reasoning, which is known variously as Inductive Generalization, Generalization, and Statistical Generalization: X% of all observed A’s are B’’s. Therefore X% of all A’s are Bs. The fallacy is committed when not enough A’s are observed to warrant the conclusion. If enough A’s are observed then the reasoning is not fallacious.
EX: 4 or 5 people that have mullets out of 2,000 people does not mean that mullets are coming back,

Post Hoc, Ergo Propter Hoc
This fallacy follows the basic format of: A preceded B, therefore A caused B, and therefore assumes cause and effect for two events just because they are temporally related (the latin translates to “after this, therefore because of this”).
EX: I wore my purple underwear to the game on Friday and we won, so if I wear them again we will win.

Contradictory Premises
(also known as a logical paradox): Establishing a premise in such a way that it contradicts another, earlier premise.
EX: If God can do anything… argument

Ad Misericordiam
“Appeal to pity, or Appeal to sympathy” – also “The Galileo Argument” someone tries to win support for an argument or idea by exploiting his or her opponent’s feelings of pity or guilt. It is a specific kind of appeal to emotion.
EX: Just because Lance Armstrong overcame cancer and I love him does not mean he is a cheater.

False (Bad) Analogy
comparison of two situations that have nothing to do with one another. The arguer claims the situations are highly relatable, but they aren’t.
EX: Lance Armstrong has cancer, therefore he will not cheat.
