flaw types LSAT 2020 Flashcards
strawman argument
misrepresenting/exaggerating/ completely fabricating someone’s argument to make your own argument sound reasonable.
ex:
Warren: we should fund healthcare and education.
Bill: Warren wants to leave our country defenseless by cutting military spending!
false cause
presuming that two things happening at the same time means that they have a casual relationship
~ correlation does not equal causation ~
sometimes correlation is coincidental or they share the common cause
middle ground
claiming a compromise, or middle point, between two extremes must be the truth
half way between a truth and a lie is still a lie.
sometimes a thing is not true, or a compromise is simply untrue
ex:
Holly: vaccines cause autism.
Iris: scientifically speaking that is not true and has been debunked.
Eric: ok but let’s just say then that autism causes some autism.
(no!! not true!!)
appeal to emotion
attempting to manipulate an emotional response in place of a compelling or valid argument
emotions include: pity, hatred, pride, anger, envy, fear
Jesse: I don’t want to eat brains again tonight
Jesse’s dad: there are starving vampires in the world rn!!! eat ur brains!!
the gamblers fallacy
thinks that “runs” happens to statistically independent phenomena
Gambler: I’ve been losing the last twenty rounds, so I must hit it big the next run!
Kid: I got heads twice before so next I must get tails
what happened before won’t influence what will happen next
bandwagon
pointing to the popularity of an idea or to the fact that many people do something as a form of validation
the popularity of an idea has no bearing on the validity of an argument
ex: the earth is not flat even though flat earthers, like Lupe, thinks it is
appeals to authority
using a person or institution opinion as a way to claim something is true
ex. evolution is fake because the pope and the church say so!
the opinion of such individuals or institutions have no bearing on the validity of the argument
the fallacy fallacy
it’s a double fallacy to use a fallacy to response to an argument , that could either be true or false [valid or invalid], that was using a fallacy to prove its validity
ex:
Joey: we have to drink the tummy teas because my friend that works at the gym said so!! {appeals to authority}
Amanda: tummy teas don’t work!! we should instead focus on protecting the planet instead of wasting time on our external appearance (appeals to emotion)
slippery slope
presuming that if we allow A to happen, then S will eventually happen too, so A must not happen
Ex: same-sex couples should not marry bc then people will want to marry their dogs!!!
shifting attn away from or avoiding issue at hand and using fear or extreme hypotheticals to do so, especially when zero evidence was presented
ad hominem
attacking someone’s character or personal attributes/traits to undermine or cast doubt on claims instead of engaging with their argument.
ex:
Sally: we need to abolish the police
Mark: We shouldn’t listen to Sally because they were once arrested and they smell weird~!!
composition/division
parts to whole; whole to parts
just because something is true for a part of it does not mean that it is true for the whole and vice versa
ex. joey, a wee child, thinks that bc his atoms are invisible then he too must be invisible
the branch of the tree is rotting therefore the whole tree is rotten
no true stan
appeals to purity as a way to dismiss releveant criticisms or flaws of the argument
takes stereotypical things about group
ex.
JT: Nicki Minaj stans know her Monster verse
Meg Thee Stallion: I’m a stan and I don’t know the Monster verse
JT: then you’re not a TRUE stan!!!!
This is a post-rationalization is a way of avoiding valid criticisms of one’s argument
genetic
similar to ad hominem in that it’s using existing negative perceptions to make someone’s argument look bad…… this fallacy shifts attention to someone or something’s origin as a way to avoid the argument
News (NOT foxnews): 45 has used quid pro quo
45: DO NOT TRUST THE MEDIA!!!! U know anything coming from the media is FALSE
tu quoque
uses the alleged past actions of the arguer to discredit the argument
ex: leo decap can’t lecture on global warming when he uses a private jet weekly
type of adhomemim
argument from personal incredulity
bases its evidence on someone’s inability to understand or imagine as the reason that it must be true or false
“i can’t imagine it being false so it must be true”
“i dont understand this topic so it must be false”
ex:
i dont understand gender identity so transgender people are lying // it is not true
