fallacies Flashcards
(37 cards)
what are fallacies?
a defect in an argument
-> that arises from either
- a mistake in reasoning or
- the creation of an illusion that makes a bad argument appear good
what are formal fallacies?
- may be idenified by merely examining the structure of an argument
- only found in deductive arguments that have identifiable forms
what are informal fallacies ?
can be detected only by examining the conent of the agrument
-> require extra information
what are examples of fallacies of relevance?
- appeal to force
- appeal to pity
- appeal to the people
- argument against the person
- accident
- straw man
- missing the point
- red herring
what is the appeal to force?
- arguer poses a conclusion to another person and tells that person that harm will come to them if they do not accept the conclusion
- threat is logically irrelevant to the subject matter
–> argument based on that is fallacious - accomplishes its purpose by psychologically impeding the listener from acknowledging a missing premise that would be seen as false or questionable
-> often occurs when children argue
what is the appeal to pity?
occurs when an arguer attempts to support a conclusion by merely evoking pity from the audience
- conclusion of this argument is not logically relevant to agruers set of pathetic circumstances
- arguments from compassion:
supply information about why that person is genuinely deserving of help or special consideration
what is a fallacy of relevance?
arguments have premises that are logically irrelevant to the conclusion but may appear psychologically relevant, so that the conclusion may seem to follow from the premises
what is the appeal to the people?
uses the desire to be loved, and valued to get the audience to accept a conclusion
> direct approach
= arguer addresses a large group of people and excites their emotions to win acceptance for a conclusion
= appeal to fear
> indirect approach
= arguer aims their appeal not at the crowd but at one or more separate individuals focusing on some aspects
= bandwagon argument
= appeal to vanity
= appeal to snobbery
= appeal to tradition
appeal to the people:
what is the appeal to fear?
= direct
fear mongering:
occurs when an arguer ** trumps up a fear** of something in the mind of a crowd and then uses that fear as a premise for a conclusion
appeal to the people:
what is the appeal to vanity?
= indirect
involves linking the love, admiration, and approval of the crowd with some famous figure who is loved, admired, or approved of
-> often used by advertisers
appeal to the people:
what is the appeal to snobbery
= indirect
arguer appeals to a smaller group that is supposed to be superior in some way
-> if listener wants to be part of this group, they think in a certain way
appeal to the people:
what is the appeal to tradition?
= indirect
arguer cites the fact that something has become tradition as grounds for some conclusion
appeal to the people:
what is the bandwagon argument?
= indirect
everybody believes xy, therefore, you should believe in xy too
what is an accident (fallacy)
committed when a general rule is applied to a specific case it was not intended to cover
what is the straw man ?
committed when an agruer distorts an opponent´s argument for the purpose of more easily attacking it,
demolishes the distorted argument
and then concludes that the original argument has been demolished
what is missing the point?
special form of irrelevance:
occurs when the premise of an argument support one particular conclusion but then a different conclusionis drawn that is vaguely related to the correct conclusion
what is the red herring fallacy?
occurs when the arguer diverts the attention of the audience by changing the subject to a different, but sometimes subtly related one
finishes by drawing a conclusion about the different issue/ presuming that some conclusion has been established
-> draws listener off track
what are examples for fallacies of weak induction?
- appeal to unqualified authority
- appeal to ignorance
- hasty generalisations (converse accident)
- false cause
- slippery slope
- weak analogy
what is the appeal to unqualified authority?
variety of argument from authority: occurs when cited authority lacks credibility
what is the appeal to ignorance?
involves something that is incapable of being proven or something that has not yet been proven
what are hasty generalisations/ composition ?
occurs when there is a reasonable likelihood that the sample is not representative of the group:
argument that draws a conclusion about all members of a group from evidence, that pertains to a selected sample
-> conclusion = general statement (= hasty generalisation)
-> conclusion = class statement (= composition)
what is a false cause?
occurs when the link between premises and conclusion depends on some imagined causal connection that probably does not exist
what is the slippery slope?
variety of false cause fallacy:
conclusion of an argument rests on an alleged chain reaction and there is not sufficient reason to think that the chain reaction will actually take place
-> rest on a mere emotional conviction on the part of the arguer
a policy is bad and they name many direct consequences that allegedly follow if the action is taken
what is weak analogy?
affects inductive arguments from analogy:
committed when analogy is not strong enough to support the conclusion that is drawn
