Hitchens's razor is an epistemological razor expressed by writer Christopher Hitchens. It says that the burden of proof regarding the truthfulness of a claim lies with the one who makes the claim; if this burden is not met, then the claim is unfounded, and its opponents need not argue further in order to dismiss it.
The concept, named after journalist, author, and avowed atheist Christopher Hitchens, echoes Occam's razor. The dictum appears in Hitchens's 2007 book titled God Is Not Great: How Religion Poisons Everything. It takes a stronger stance than the Sagan standard ("Extraordinary claims require extraordinary evidence"), instead applying to even non-extraordinary claims.

What can be asserted without evidence can also be dismissed without evidence. This is even more true when the ‘evidence’ eventually offered is so shoddy and self-interested.

[William Ockham] devised a 'principle of economy,' popularly known as 'Ockham’s razor,' which relied for its effect on disposing of unnecessary assumptions and accepting the first sufficient explanation or cause. 'Do not multiply entities beyond necessity.' This principle extends itself. 'Everything which is explained through positing something different from the act of understanding,' he wrote, 'can be explained without positing such a distinct thing.'
