There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone who saw this today donated $5, we would meet our goal for 2019.

Hierarchy of disagreement
| Part of the series on|
Logic and rhetoric
The hierarchy of disagreement is a concept proposed by computer scientist Paul Graham in his 2008 essay How to Disagree. Graham's hierarchy has seven levels, from name calling to "Refuting the central point". According to Graham, most disagreements come on one of seven levels:
- 1: Refuting the central point (explicitly refutes the central point).
- 2: Refutation (finds the mistake and explains why it's mistaken using quotes).
- 3: Counterargument (contradicts and then backs it up with reasoning and/or supporting evidence).
- 4: Contradiction (states the opposing case with little or no supporting evidence).
- 5: Responding to tone (criticizes the tone of the writing without addressing the substance of the argument.
- 6: Ad Hominem (attacks the characteristics or authority of the writer without addressing the substance of the argument).
- 7: Name-calling (sounds something like, "You are an idiot.").
