Hanlon's razor is an aphorism expressed in various ways, including:

Never attribute to malice that which is adequately explained by stupidity.[1]

It suggests a way of eliminating unlikely explanations ("attributions") for human behavior and its consequences. Statements of this kind are known as philosophical razors. It is an eponymous law, probably named after a Robert J. Hanlon.

Inspired by Occam's razor,[2] the aphorism was popularized in this form and under this name by the Jargon File, a glossary of computer programmer slang.[3][1] In 1990, it appeared in the Jargon File described as a "'murphyism' parallel to Occam's Razor".[4] Later that same year, the Jargon File editors noted lack of knowledge about the term's derivation and the existence of a similar epigram by William James.[1][5] In 1996, the Jargon File entry on Hanlon's Razor noted the existence of a similar quotation in Robert A. Heinlein's short story "Logic of Empire" (1941), with speculation that Hanlon's Razor might be a corruption of "Heinlein's Razor".[6] (The character "Doc" in Heinlein's story described the "devil theory" fallacy, explaining, "You have attributed conditions to villainy that simply result from stupidity.")[7]

In 2001, Quentin Stafford-Fraser published two blog entries citing e-mails from one Joseph E. Bigler[8][9] about how the quotation originally came from Robert J. Hanlon of Scranton, Pennsylvania, as a submission for a book compilation of various jokes related to Murphy's law published in Arthur Bloch's Murphy's Law Book Two: More Reasons Why Things Go Wrong! (1980).[10] Subsequently, in 2002, the Jargon File entry noted the same, though not definitively.[11]

"Heinlein's Razor" has since been defined as variations on "Never attribute to malice that which can be adequately explained by stupidity, but don't rule out malice."[citation needed] This quotation is falsely attributed to Albert Einstein in Peter W. Singer's book Wired for War (2009).[12]

In British politics, the same concept is often expressed by variants of the phrase “cock-up, not conspiracy”, with Margaret Thatcher's press secretary Sir Bernard Ingham saying "Many journalists have fallen for the conspiracy theory of government. I do assure you that they would produce more accurate work if they adhered to the cock-up theory."[13]
