logical fallacies Flashcards
logical fallacy:
arguments that are flawed by their very nature or structure; an error in reasoning that renders an argument invalid
ad hominem
target: attacking your opponents character or personal traits to undermine their argument: personal attack
ambiguity
candle/two faces: using double meanings or ambiguities of language to mislead or misrepresent the truth
anecdotal
speech bubble: using personal experience or an isolated example instead of a valid argument, especially to dismiss statistics
appeal to fear
spider: attempting to frighten people into agreeing with the arguer by threatening their well being or predicting unrealistically dire consequences
appeal to nature
leaf: making the argument that because something is ‘natural’ it is therefore valid, justified, good, or ideal
bandwagon
wagon: appealing to the popularity or the fact that many people do something as an attempted form of validation
cherry picking
cherry: carefully choosing certain pieces of evidence while ignoring others to suit ones argument
circular reasoning
question mark in circle: using a conclusion as evidence to prove itself true, creating a circular logic
false dichotomy
checkered box: where two alternative options are presented as the only possibilities, when in fact more possibilities exist
false equivalency
pear≠orange: an inaccurate, inappropriate, or misleading comparison between two things
faulty appeal to authority
crown: insisting that a claim is true simply because a valid authority or expert on the issue said it was true, without any other supporting evidence offered
faulty appeal to emotion
heart: manipulating people’s feelings to get an emotional response rather than present a valid or compelling argument
genetic
genetic helix: judging something as good or bad based on the reputation of where it comes from, or from who it comes
hasty generalization
people: leaps to a conclusion based on a small sample size, rather than looking at statistics that are much more in line with the typical or average situation
loaded question
bomb/?: asking a question that has an assumption built into it so that it can’t be answered without appearing guilty
non sequitur
snowflake/skull: is a statement where a conclusion is made that doesn’t logically follow from the premise; using a piece of evidence that doesn’t fit the overall argument
red herring
fish: uses misleading or unrelated evidence to purposefully change the topic in order to distract from the original topic
shifting the burden of proof
person holding the box: making a claim without proper evidence, then demanding the opponent disprove it; making your opponent responsible for proving your claims
slippery slope
person falling: asserting that if we allow one relatively minor thing to happen, it will create a chain reaction that leads to a disastrous outcome; a snowball effect
straw man
scarecrow: distorting or simplifying someones argument to make it easier to attack, then addressing that distortion rather than the actual claim.
