Fallacies Flashcards
Accident
This fallacy occurs when one applies a generalisation to an individual case that it does not properly govern. This occurs in two different ways:
i. ) when it is assumed what is correct in normal circumstances remains correct in an abnormal situation.
ii. ) When it is assumed that what is acceptable in unusual circumstances remains so when normal circumstances apply.
Strawman
This fallacy occurs when someone misrepresents an opponent’s arguments and thus attacks the wrong issue.
Complex Question
This fallacy occurs when a question is asked in such a way as to presuppose the truth of some assumption buried in the question.
a) Loaded questions - here the wording of the question limits the responder to an answer of yes or no hence admitting or denying the assumption in the question.
b) Loaded question - here the nature if the question is such that the response of the person provides them with only limited choice in the way they can respond.
The Fallacy of Biased Sampling
This occurs when the evidence (or sample) is not representative of the whole population but it is used as it is.
This fallacy occurs when a conclusion is reached about a group on the basis of a survey, which is unrepresentative of the population.
Division
This fallacy involves a claim that what is true about a collection or group is therefore true about each element or member of that group.
Appeal to Ignorance (Ad Ignoratium)
When an arguer claims that a conclusion is true solely because it has not been proven false, rather than providing evidence for their claim.
Bald-Hairy Fallacy
This fallacy involves the assumption that because there is a vague borderline between two things, that there is in fact no difference between them.
Fallacy of Central Tendency
This fallacy occurs when someone argues from an average characteristic to an individual characteristic or vice versa.
Monte Carlo Fallacy (Gambler’s Fallacy)
This fallacy occurs when a person treats an independent event as if it were a dependent event.
Fallacy of Stereotyping
This fallacy occurs when a common stereotype is used as a justification for a claim, without evidence that the stereotype applies.
False Cause (Post Hoc Ergo Propter Hoc)
This fallacy occurs when one treats as the cause of a thing what is not really the cause of that thing, or more generally, when one blunders in reasoning that is based upon two events affecting each other. It is often seen when it is assumed that just because A precedes B then A must definitely have caused B.
Slippery Slope
This fallacy occurs when an argument is claimed to appeal to a chain of events which are claimed to lead from acceptance of an opponent’s proposal to some undesirable consequences.
Circular/Begging the Question (Peititio Principii)
This fallacy occurs when an arguer assumes to be true what the are actually seeking to prove is true. It occurs when somehow the conclusion has already been assumed in the premises.
Forgetful Induction
This occurs when important or relevant information is overlooked
Black and White Thinking
This is a form of strawman argument and is committed by someone who deliberately assumes an exaggerated position for his opponent.
