Hanlon's razor is an adage or rule of thumb that states "never attribute to malice that which is adequately explained by stupidity."[1] Known in several other forms, it is a philosophical razor that suggests a way of eliminating unlikely explanations for human behavior. It is likely named after Robert J. Hanlon, who submitted the statement to Murphy's Law Book Two (1980).[1] Similar statements have been recorded since at least the 18th century.
Origin
A similar quotation appears in Robert A. Heinlein's novella Logic of Empire (1941).[2] The character "Doc" in Heinlein's story described the "devil theory" fallacy, explaining, "You have attributed conditions to villainy that simply result from stupidity."[3]
The quotation as such was a submission credited in print to Robert J. Hanlon of Scranton, Pennsylvania, for a compilation of various jokes related to Murphy's law that were published in Arthur Bloch's Murphy's Law Book Two: More Reasons Why Things Go Wrong! (1980).[1] It is unknown whether Hanlon knew of Heinlein's story or whether he independently constructed the phrase.[citation needed]
Hanlon's razor became well-known after its inclusion in the Jargon File, a glossary of computer programmer slang, since 1990.[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.[5] In 1996, the Jargon File entry on Hanlon's Razor noted the existence of the phrase in Heinlein's novella, with speculation that Hanlon's Razor might be a corruption of "Heinlein's Razor".[2] The link to Murphy's law was described in a pair of 2001 blog entries by Quentin Stafford-Fraser, citing emails from Joseph E. Bigler.[6][7] Subsequently, in 2002, the Jargon File entry noted the same.[8] Current Jargon File refers to it as a "Murphyism".[9]
The phrase was inspired by Occam's razor.[10]
Other variations of the idea
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] An alternate expression of the idea comes from Jane West, in her 1812 novel The Loyalists: An Historical Novel:[11] "Let us not attribute to malice and cruelty what may be referred to less criminal motives."[13]: 134 A similar quote is also misattributed to Napoleon.[11] Andrew Roberts, in his biography of Winston Churchill, quotes from Churchill's correspondence with King George VI in February 1943 regarding disagreements with Charles De Gaulle: "'His 'insolence ... may be founded on stupidity rather than malice.'"[14]: 771
