3. Premises & Fallacies Flashcards
fallacies
general categories of bad arguments that are commonly used
begging the question
attempting to establish the conclusion of the argument by using the conclusion as a premise
false dichotomy
wrongly assuming that there are only two alternatives to consider
red herring
deliberately raising an irrelevant issue during an argument
virtue/guilt by association
accepting/rejecting a claim because of the people/groups associated with it
appeal to the person (ad hominem)
rejecting a claim by criticizing the person making it rather than the claim itself
equivocation
lack of logical strength due to ambiguity in an argument
i.e. “no man”
appeal to ignorance
arguing that the lack of evidence against a claim establishes it
appeal to tradition/novelty
arguing that the claim must be true because it’s traditional
appeal to popularity
arguing that a claim is true because it is popular
appeal to authority
arguing that a claim is true because a person/group of authority supports it
anecdotal evidence
using examples one comes across throughout life to establish a claim (typically not enough and they are subject to selection effects)
slippery slope
assuming that one step will lead to further, undesirable steps with no good reason
decision-point fallacy
arguing that because a line of distinction can’t be drawn at any point in the process, there are no differences or gradations in it (i.e. baldness)
