Fallacies Flashcards
Fallacies
faulty patterns of reasoning and arguing that tend to mislead us. Sometimes they involve invalid patterns of reasoning (like affirming the consequent) other times, they involve emotional triggers that produce beliefs that aren’t supported by rational reflection
Ad hominem (attacking the person)
Claim is rejected on the basis of some irrelevant fact about the person presenting the claim
Appeal to false authority
someone’s testimony is cited to prove a point, but the person in question is not a legitimate authority on the subject
Begging the question
One of the premises logically presupposes that the conclusion is true
False dilemma
Standard disjunctive syllogism, but with a false premise. The p or q premise ignores other relevant possibilities, and therefore, the argument fails (narrows argument to fewer conclusions then there are)
Appeal to ignorance
There is no evidence against p; therefore, p
Fallacy of equivocation
The meaning of one word is changed in the course of the argument in an attempt to justify the conclusion
Appeal to force
a proposition is accepted because of the threat of force
Appeal to the majority
The majority believes p, therefore p is true
Post hoc ergo propter hoc
Because A happened before B in time, A was the cause of B (and while A & B may be totally unrelated)
