fallacies Flashcards
unwarranted premise
the premise is not true (e.g. it is not a well-known fact that elephants love to ride tricycles)
begging the question/circular reasoning
relies on an implicit premise (enthymeme) and the reasoning ends up where it started (e.g. fetuses are already fully separate bodies that happen to be in mother’s body)
complex question
yes or no: both imply something (e.g. have you stoped abusing drugs yet?)
black & white thinking/false dichotomy
you are given two options: what was trump supposed to do- letting biden get away with stealing the election or encourage patriotic citizens to rise up?
straw man
occurs when someone takes another person’s argument or point, distorts it or exaggerates it in some kind of extreme way, and then attacks the extreme distortion as if that is really the claim the first person is making.
e.g. (by mandating abortions, the human race will die out withing a single generation.)
obscurantism
sophisticated words; usually dishonest in over-selling the strengths of a postion
equivocation
semantic of lexical ambiguity (when the word has one or more meanings)
e.g. nothing is better than perfect bliss; but a ham sandwich is better that nothing=> a ham sandwich is better that perfect bliss
amphiboly
ambiguity arises from grammar
literalism
taking things literally
division
illicitly transferring a property of a whole to its parts
e.g. about 14% of us is black, biden is black => biden is black
composition
illicitly transferring property of the part to the whole
e.g. atoms are too small to see w naked eye; biden is made out of atoms=> biden is too small to be seen w naked eye.
vagueness
doesn’t offer specific details
e.g. go out and play a game with 5-year old causing (you can play poker or russian roulette)
denying the antecedent
the if-clause is antecedent; the main clause is consequent
e.g. (if there is no fire => there is no oxygen)
affirming the consequent
if there is oxygen, there is fire
disjunctive fallacy
two different interpretations of the word ‘or’
inclusive: both or’s are correct
exclusive: one or the other but not both
