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

"Never attribute to malice that which can be adequately explained by stupidity."[1]

Probably named after a Robert J. Hanlon, it is a philosophical razor which suggests a way of eliminating unlikely explanations for human behavior.

Origin[edit]

Inspired by Occam's razor,[2] the aphorism became known in this form and under this name by the Jargon File, a glossary of computer programmer slang.[3][1] 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.[4] In 1996, the Jargon File entry on Hanlon's Razor noted the existence of a similar quotation in Robert A. Heinlein's novella Logic of Empire (1941), with speculation that Hanlon's Razor might be a corruption of "Heinlein's Razor".[5] (The character "Doc" in Heinlein's story described the "devil theory" fallacy, explaining, "You have attributed conditions to villainy that simply result from stupidity.")[6]

In 2001, Quentin Stafford-Fraser published two blog entries citing e-mails from Joseph E. Bigler[7][8] explaining that the quotation originally came from Robert J. Hanlon of Scranton, Pennsylvania, as a submission (credited in print) 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).[9] Subsequently, in 2002, the Jargon File entry noted the same.[10]

Other variations of the idea[edit]

Earlier attributions to the idea go back to at least the 18th century.[11] First published in German (1774) Johann Wolfgang von Goethe wrote in The Sorrows of Young Werther (as translated):[11]

Misunderstandings and lethargy perhaps produce more wrong in the world than deceit and malice do. At least the latter two are certainly rarer.[12]

A more concise expression of the idea comes from Jane West, in her novel The Loyalists (1812):[11]

Let us not attribute to malice and cruelty what may be referred to less criminal motives.[13]

A similar quote is also misattributed to Napoleon.[11]
