Fallacy Flashcards
Fallacies
defects that weaken arguments
Hasty generalization
making assumptions about a whole group or range of cases based on a sample that is inadequate.
Missing the point
premises of an argument support a particular conclusion-but not the one the arguer actually draws.
Post hoc (false cause)
Assuming that because B comes after A, A caused B.
Slippery Slope
arguer claims that a sort of chain reaction will take place, but there’s not really enough evidence for that assumption.
Weak Analogy
If the two things being compared aren’t really alike in the relevant respects.
Appeal to authority
attempting to get readers to agree with us simply by impressing them with a famous name or by appealing to a supposed authority who really isn’t much of an expert.
Ad populum
arguer takes advantage of the desire most people have to be liked and to fit in with others and uses that desire to get the audience to accept his or her argument.
Ad hominem and tu quoque
conclusion in these arguments is usually “You shouldn’t believe So-and-So is argument.”
Appeal to Pity
arguer tries to get people to accept a conclusion by making them feel sorry for someone.
Appeal to ignorance
arguer basically says, “Look, there’s no conclusive evidence on the issue at hand. Therefore, you should accept my conclusion on this issue.”
Straw man
arguer sets up a weak version of the opponent’s position and tries to score points by knocking it down.
Red Herring
Partway through an argument, the arguer goes off on a tangent, raising a side issue that distracts the audience from what’s really at stake.
False dichotomy
arguer sets up the situation so it looks like there are only two choices.
Fallacies of Relevance
appeal to evidence or examples that are not relevant to the argument at hand.
Appeal to Force
uses force, or threat of force, or some other unpleasant backlash to make the audience accept a conclusion.
Genetic Fallacy
the claim that an idea, product, or person must be untrustworthy because of its racial, geographic, or ethnic origin.
Personal Attack
attacking or praising the people who make an argument rather than discussing the argument itself.
Subcategory of Personal Attack: Abusive
argue that proposals, assertions, or arguments must be false or dangerous because they originate with atheists, Christians, Muslims, communists, capitalists, the John Birch Society, Catholics, anti-Catholics, racists, anti-racists, feminists, misogynists (or any other group) is fallacious.
Subcategory of Personal Attack: Circumstantial
To argue that an opponent should accept or reject an argument because of circumstances in his or her life.
Argumentum ad Populum
using an appeal to popular assent
Bandwagon Approach
A basic approach to Argumentum ad Populum. Asserts that since the majority of people believes an argument or chooses a particular course of action, the argument must be true.
Patriotic Approach
asserts that a certain stance is true or correct because it is somehow patriotic.
Snob Approach
doesn’t assert “everybody is doing it”, but rather that “all the best people are doing it.”
