You argued that because something is 'natural' it is therefore valid, justified, inevitable, good or ideal.Many 'natural' things are also considered 'good', and this can bias our thinking; but naturalness itself doesn't make something good or bad. For instance murder could be seen as very natural, but that doesn't mean it's good or justifiable.

Appeal to nature

You said that 'runs' occur to statistically independent phenomena such as roulette wheel spins.This commonly believed fallacy can be said to have helped create an entire city in the desert of Nevada USA. Though the overall odds of a 'big run' happening may be low, each spin of the wheel is itself entirely independent from the last. So whilst there may be a very small chance that heads will come up 20 times in a row if you flip a coin, the chances of heads coming up on each individual flip remain 50/50, and aren't influenced by what happened before.

The gambler's fallacy

You assumed that one part of something has to be applied to all, or other, parts of it; or that the whole must apply to its parts.Often when something is true for the part it does also apply to the whole, or vice versa, but the crucial difference is whether there exists good evidence to show that this is the case. Because we observe consistencies in things, our thinking can become biased so that we presume consistency to exist where it does not.

Composition/division

You used a double meaning or ambiguity of language to mislead or misrepresent the truth.Politicians are often guilty of using ambiguity to mislead and will later point to how they were technically not outright lying if they come under scrutiny. The reason that it qualifies as a fallacy is that it is intrinsically misleading.

Ambiguity

You judged something as either good or bad on the basis of where it comes from, or from whom it came.This fallacy avoids the argument by shifting focus onto something's or someone's origins. It's similar to an ad hominem fallacy in that it leverages existing negative perceptions to make someone's argument look bad, without actually presenting a case for why the argument itself lacks merit.

Genetic

You misrepresented someone's argument to make it easier to attack. By exaggerating, misrepresenting, or just completely fabricating someone's argument, it's much easier to present your own position as being reasonable, but this kind of dishonesty serves to undermine honest rational debate.

Strawman

You attempted to manipulate an emotional response in place of a valid or compelling argument.Appeals to emotion include appeals to fear, envy, hatred, pity, pride, and more. It's important to note that sometimes a logically coherent argument may inspire emotion or have an emotional aspect, but the problem and fallacy occurs when emotion is used instead of a logical argument, or to obscure the fact that no compelling rational reason exists for one's position.

Appeal to emotion

You cherry-picked a data cluster to suit your argument, or found a pattern to fit a presumption.This 'false cause' fallacy is coined after a marksman shooting randomly at barns and then painting bullseye targets around the spot where the most bullet holes appear, making it appear as if he's a really good shot. Clusters naturally appear by chance, but don't necessarily indicate that there is a causal relationship.

The texas sharpshooter

You claimed that a compromise, or middle point, between two extremes must be the truth.Much of the time the truth does indeed lie between two extreme points, but this can bias our thinking: sometimes a thing is simply untrue and a compromise of it is also untrue. Half way between truth and a lie, is still a lie.

Middle ground

You used a personal experience or an isolated example instead of a sound argument or compelling evidence.It's often much easier for people to believe someone's testimony as opposed to understanding complex data and variation across a continuum. Quantitative scientific measures are almost always more accurate than personal perceptions and experiences, but our inclination is to believe that which is tangible to us, and/or the word of someone we trust over a more 'abstract' statistical reality.

Anecdotal

You presented a circular argument in which the conclusion was included in the premise.This logically incoherent argument often arises in situations where people have an assumption that is very ingrained, and therefore taken in their minds as a given. Circular reasoning is bad mostly because it's not very good.

Begging the question

You appealed to popularity or the fact that many people do something as an attempted form of validation.The flaw in this argument is that the popularity of an idea has absolutely no bearing on its validity.If it did, then the Earth would have made itself flat for most of history to accommodate this popular belief.

Bandwagon

You attacked your opponent's character or personal traits in an attempt to undermine their argument.Ad hominem attacks can take the form of overtly attacking somebody, or more subtly casting doubt on their character or personal attributes as a way to discredit their argument. The result of an ad hom attack can be to undermine someone's case without actually having to engage with it.

Ad hominem

You asked a question that had a presumption built into it so that it couldn't be answered without appearing guilty.Loaded question fallacies are particularly effective at derailing rational debates because of their inflammatory nature - the recipient of the loaded question is compelled to defend themselves and may appear flustered or on the back foot.

Loaded question

You presented two alternative states as the only possibilities, when in fact more possibilities exist.Also known as the false dilemma, this insidious tactic has the appearance of forming a logical argument, but under closer scrutiny it becomes evident that there are more possibilities than the either/or choice that is presented. Binary, black-or-white thinking doesn't allow for the many different variables, conditions, and contexts in which there would exist more than just the two possibilities put forth. It frames the argument misleadingly and obscures rational, honest debate.

Black-or-white

You said that because an authority thinks something, it must therefore be true.It's important to note that this fallacy should not be used to dismiss the claims of experts, or scientific consensus. Appeals to authority are not valid arguments, but nor is it reasonable to disregard the claims of experts who have a demonstrated depth of knowledge unless one has a similar level of understanding and/or access to empirical evidence.

Appeal to authority

You said that if we allow A to happen, then Z will eventually 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.

Slippery slope

You moved the goalposts or made up an exception when your claim was shown to be false.Humans are funny creatures and have a foolish aversion to being wrong. Rather than appreciate the benefits of being able to change one's mind through better understanding, many will invent ways to cling to old beliefs. One of the most common ways that people do this is to post-rationalize a reason why what they thought to be true must remain to be true.

Special pleading

You made what could be called an appeal to purity as a way to dismiss relevant criticisms or flaws of your argument.In this form of faulty reasoning one's belief is rendered unfalsifiable because no matter how compelling the evidence is, one simply shifts the goalposts so that it wouldn't apply to a supposedly 'true' example. This kind of post-rationalization is a way of avoiding valid criticisms of one's argument.

No true scotsman

You presumed that because a claim has been poorly argued, or a fallacy has been made, that the claim itself must be wrong.It is entirely possible to make a claim that is false yet argue with logical coherency for that claim, just as it is possible to make a claim that is true and justify it with various fallacies and poor arguments.

The fallacy fallacy

You avoided having to engage with criticism by turning it back on the accuser - you answered criticism with criticism.Pronounced too-kwo-kweh. Literally translating as 'you too' this fallacy is also known as the appeal to hypocrisy. It is commonly employed as an effective red herring because it takes the heat off someone having to defend their argument, and instead shifts the focus back on to the person making the criticism.

Tu quoque

You said that the burden of proof lies not with the person making the claim, but with someone else to disprove.The burden of proof lies with someone who is making a claim, and is not upon anyone else to disprove. The inability, or disinclination, to disprove a claim does not render that claim valid, nor give it any credence whatsoever. However it is important to note that we can never be certain of anything, and so we must assign value to any claim based on the available evidence, and to dismiss something on the basis that it hasn't been proven beyond all doubt is also fallacious reasoning.

Burden of proof

Because you found something difficult to understand, or are unaware of how it works, you made out like it's probably not true. Complex subjects like biological evolution through natural selection require some amount of understanding before one is able to make an informed judgement about the subject at hand; this fallacy is usually used in place of that understanding.

Personal incredulity

You presumed that a real or perceived relationship between things means that one is the cause of the other.Many people confuse correlation (things happening together or in sequence) for causation (that one thing actually causes the other to happen). Sometimes correlation is coincidental, or it may be attributable to a common cause.

False cause

A logical fallacy is a flaw in reasoning. Logical fallacies are like tricks or illusions of thought, and they're often very sneakily used by politicians and the media to fool people. Don't be fooled!
