Fallacy Flashcards
fallacy
defects that weaken arguments
hasty generalization
making assumptions about a whole group or range of cases based on a sample that is inadequate stereotypes are a common example
missing the point
when the premise of an argument is missed
post hoc
aka false cause: assuming that because B came after A, A caused B
slippery slope
the arguer claims that a sort of chain reaction, usually ending in some dire consequence, will take place, but there’s really not enough evidence for that assumption
weak analogy
many arguments rely on an analogy between two or more objects, ideas, or situations,. If the two things that are being compared aren’t really alike in the relevant respects, the analogy is a weak one
appeal to authority
when a writer tries to add strength to their arguments by referring to respected sources or authorities
ad populum
the arguer takes advantage of the desire most people have to be liked and to fit in with the others and uses desire to try to get the audience to accept his or her argument
ad hominem and tu quoque
fallacies that direct our attention on people rather than the arguments or evidence
appeal to pity
when the arguer tries to get people to accept a conclusion by making them feel sorry for someone
appeal to ignorance
“Look, there’s no conclusive evidence on the issue at hand. Therefore, you should accept my conclusion on this issue.”
straw man
the arguer sets up a weak version of the opponents 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 whats really at stake. Often, the arguer never returns to the original issue.
false dichotomy
type of informal fallacy that involves a situation in which limited alternatives are considered, when in fact there is at least one additional option
fallacies of relevance
these fallacies appeal to evidence or examples that are not relevant to the argument at hand
