Hierarchy of disagreement

The hierarchy of disagreement is a concept proposed by computer scientist Paul Graham in his 2008 essay How to Disagree.[1] Graham's hierarchy has seven levels, from name calling to "Refuting the central point". The point of the concept is to help people make better arguments for their beliefs, as well as have more constructive disagreements with those whose views come into conflict with theirs. Preferably, one's argument should be as high on the pyramid as possible while still being intelligible, as arguments of this nature are stronger.

Note that 4 through 7 on the pyramid are fallacious arguments, so it is best to avoid these entirely. Nevertheless, there isn't always a clear point where one step on the hierarchy crosses over into another (though that doesn't mean there is no difference between the states). Also, the tone argument - 5 - may be valid in cases where tone is relevant to the discussion.

Levels on the hierarchy

DH6: Refuting the central point

The most convincing form of disagreement. Here you identify the main point someone is making and destroy it. The difference between this and DH5 (Refutation) is that there's no room for error - you pick the central message being conveyed by the opponent and suggest why it is flawed. It could be considered a subset of DH5 rather than a completely different level on the pyramid, as structure-wise they are identical.

DH5: Refutation

Use their own words against them! Take the argument provided by the opponent and show how it is wrong using quotes extracted from it. This takes more work than calling someone the r-word but that's because it's a better form of debate. Of course, while refutation is solid, it's still prone to error - for example, contextomy or hair splitting.

DH4: Counterargument

Rather than simply stating the opposite case, do so while backing it up with reason and evidence. So in response to "We should do X", you'd say "We should not do X because Y" instead of just "We should not do X".

DH3: Contradiction

Making it known you disagree by reversing whatever the opposing speaker said. And that's all she wrote! Also applies to the appeal to the stone. (Note: some points or arguments are so insipid they don't deserve a reply higher than this unless you really have the patience).

DH2: Responding to tone

Complaining about the way that someone said something, rather than what was actually said. Note that while tone arguments are a form of ignoratio elenchi, or the style over substance fallacy, they could be relevant in select cases where rhetoric is being discussed. Also, the term tone policing is autological so you run the risk of hypocrisy in calling someone out for doing this.

DH1: Ad Hominem

You're familiar with this, and it comes in many guises - associative, ad fidentia (or confidence attack), abusive, circumstantial and hypocritical. Effectively attacking the authority of the speaking instead of the argument.

DH0: Name-calling

The crutch of edgy 4chan kids and high school bullies alike. Simply insulting someone just isn't an argument.
