For the record, these were not created by me. They are just being shown for individuals to be able to identify them in their daily lives.
What is a logical fallacy?
A logical fallacy is a flaw in reasoning. Strong arguments are void of logical fallacies, whilst arguments that are weak tend to use logical fallacies to appear stronger than they are. They’re like tricks or illusions of thought, and they’re often very sneakily used by politicians, media, and others to fool people. Below follow some of the more common fallacies.
Misrepresenting Someone’s Argument To Make It Easier To Attack
By exaggerating, misrepresenting, or just completely fabricating someone’s argument, it’s much easier to prevent your own position as being reasonable, but this is kind of dishonest and serves to undermine honest rational debate.
Example: After will said we should put more money into health and education, Warren responded by saying he was surprised that Will hates our country so much that he wants to leave it defenseless by cutting military spending.
Asserting That If We Allow A to happen, then Z will consequently happen too, therefore A should not happen.
The problem with this reasoning is that it avoids engaging with the issue at hand, and instead shifts attention to extreme hypotheticals. Because no proof is presented to show that such extreme hypotheticals will in fact occur, this fallacy has the form of an appeal to emotion fallacy by leveraging fear. In effect the argument at hand is unfairly tainted by unsubstantiated conjecture.
Example: Colin Closet asserts that if we allow same-sex couples to marry, then the next thing we know we’ll be allowing people to marry their parents, their cars and even monkeys.
Presuming that a real or perceived relationship between things means that one is the cause of the other.
Example: Pointing to a fancy chart, a Senator shows how temperatures have been rising over the past few centuries, whilst at the same time the numbers of terrorist attacks have been increasing; thus global warming causes terrorism. [Don’t believe me? Look it up – an actual senator that said this.]
Attacking your opponent’s character or personal traits in an attempt to undermine their argument.
Example: After Sally presents an eloquent and compelling case for a more equitable taxation system, Sam asks the audience whether we should believe anything from a woman who isn’t married, was once arrested, and smells a bit weird.
Moving the goalposts to create exceptions when a claim is shown to be false.
Example: Edward Johns claimed to be psychic, but when his ‘abilities’ were tested under proper scientific conditions, they magically disappeared. Edward explained this saying that one had to have faith in his abilities for them to work.
Asking a question that has an assumption built into it so that it can’t be answered without appearing guilty.
Example: Grace and Helen were both romantically interested in Brad. One day, with Brad sitting within earshot, Grace asked in an inquisitive tone whether Helen was having any problems with a fungal infection.
The Gambler’s Fallacy
Believing that ‘runs’ occur to statistically independent phenomena such as roulette wheel spins.
Example: Red had come up six times in a row on the roulette wheel, so Greg knew that it was close to certain that black would be next up. Suffering an economic form of natural selection with this thinking, he soon lost all of his savings.
Appealing to popularity or the fact that many people do something as an attempted form of validation.
Example: Shamus pointed a drunken finger at Sean and asked him to explain how so many people could believe in leprechauns if they’re only a silly old superstition. Sean, however, had had a few too many Guinness himself and fell off his chair.
Where two alternative states are presented as the only possibilities, when in fact more possibilities exist.
Example: Whilst rallying support for his plan to fundamentally undermine citizens’ rights, the Supreme Leader told the people they were either on his side, or on the side of the enemy. [Note: George Bush did this by the way…]
Begging The Questions
A circular argument in which the conclusion is included in the premise.
Example: The word of Zorbo the Great is flawless and perfect. We know this because it says so in The Great and Infallible Book of Zorbo’s Best and Most Truest Things that are Definitely True and Should Not Ever Be Questioned.
Appeal To Authority
Using the opinion or position of an authority figure, or institution of authority, in place of an actual argument.
Example: When an individual states that vaccines are safe just because doctors say so, even though countless studies can be cited to eviscerate the ‘safety’ argument.
Appeal To Nature
Making the argument that because something is ‘natural’ it is therefore valid, justified, inevitable, good, or ideal.
Example: The medicine man rolled into town on his bandwagon offering various natural remedies, such as very special plain water. He said that it was only natural that people should be wary of ‘artificial’ medicines such as antibiotics. The converse is also true, which could be in a way called Appeal To Technology/Science.
Composition / Division
Assuming that what’s true about one part of something has to be applied to all, or other, parts of it.
Example: Daniel was a precocious child and had a liking for logic. He reasoned that atoms are invisible, and that he was made of atoms and therefore invisible too. Unfortunately, despite his thinky skills, he lost the game of hide and go seek.
Using personal experience or an isolated example instead of a valid argument.
Example: Jason said that that was all cool and everything, but his grandfather smoked, like, 30 cigarettes a day and lived until 97 – so don’t believe everything you read about meta analyses of sound studies showing proven causal relationships.
Appeal To Emotion
Manipulating an emotional response in place of a valid or compelling argument.
Example: Luke didn’t want to eat his sheep’s brains with chopped liver and brussels sprouts, but his father told him to think about the poor, starving children in a third world country who weren’t fortunate enough to have any food at all.
The Fallacy Fallacy
Presuming that because a claim has been poorly argued, or a fallacy has been made, that it is necessarily wrong.
Example: Recognizing that Amanda had committed a fallacy in arguing that we should eat healthy food because a nutritionist said it was popular, Alyse said we should therefore eat bacon double cheeseburgers every day.
Avoiding having to engage with criticism by turning it back on the accuser – answering criticism with criticism.
Example: The blue candidate accused the red candidate of committing the tu quoque fallacy. The red candidate responded by accusing the blue candidate of the same, after which ensued an hour of back and forth criticism with not much progress.
Saying that because one finds something difficult to understand that it’s therefore not true.
Example: Kirk drew a picture of a fish and a human and with effusive disdain asked Richard if he really thought we were stupid enough to believe that a fish somehow turned into a human through just, like, random things happening over time.
Burden Of Proof
Saying that the burden of proof lies not with the person making the claim, but with someone else to disprove.
Examples: Bertrand declares that a teapot is, at this very moment, in orbit around the Sun between the Earth and Mars, and that because no one can prove him wrong his claim is therefore a valid one.
Using double meanings or ambiguities of language to mislead or misrepresent the truth.
Example: When the judge asked the defendant why he hadn’t paid his parking fines, he said that he shouldn’t have to pay them because the sign said ‘Fine for parking here’ and so he naturally presumed that it would be fine to park there.
No True Scotsman
Making what could be called an appeal to purity as a way to dismiss relevant criticisms or flaws of an argument.
Example: Angus declares that Scotsmen do not put sugar on their porridge, to which Lachlan points out that he is a Scotsman and puts sugar on his porridge. Furious, like atrue Scot, Angus yells that no true Scotsman sugars his porridge.
Judging something good or bad on the basis of where it comes from, or from whom it comes.
Example: Accused on the 6 o’clock news of corruption and taking bribes, the senator said that we should all be very wary of the things we hear in the media, because we all know how very unreliable the media can be.
The Texas Sharpshooter
Cherry-picking data clusters to suit an argument, or finding a pattern to fit a presumption.
Example: The makers of Sugarette Candy Drinks point to research showing that of the five countries where Sugarette drinks sell the most units, three of them are in the top ten healthiest countries on Earth, therefore Sugarette drinks are healthy.
Saying that a compromise, or middle point, between two extremes is the truth.
Example: Holly said that vaccinations are safe, but her scientifically well-read friend Caleb said that this claim was untrue because there were dozens of studies proving otherwise. Their friend Alice offered a compromise that vaccinations are sometimes safe.
