What Is the Burden of Proof Fallacy?
The burden of proof fallacy occurs when someone makes a claim and demands that others disprove it, rather than providing evidence themselves. The person making the claim is responsible for supporting it.
Also known as Shifting the Burden of Proof, this is a informal fallacy — the error lies in the content or context of the argument rather than its formal structure.
How to Spot It
Example
"This treatment works. Prove that it doesn't." The person claiming effectiveness should provide evidence, not demand others disprove it.
A Stronger Version
"We tested this treatment in a randomized trial with 200 participants. The treatment group showed a 15% improvement compared to the control group."
Warning Signs
- Demanding others disprove a claim instead of proving it
- Making assertions without evidence and calling them 'obvious'
- Treating unproven claims as true by default
- Framing the need for evidence as unreasonable skepticism
How to Fix It
Whoever makes the claim bears the burden of proof. 'I don't have to prove it — you have to disprove it' is never a valid argument. Extraordinary claims require proportionally strong evidence.
