Reality distortion field (RDF) is a term used by Bud Tribble at Apple Computer in 1981, to describe company co-founder Steve Jobs's charisma and its effects on the developers working on the Macintosh project. Tribble said that the term came from Star Trek. In the Menagerie episode, it was used to describe how the aliens created their own new world through mental force.
Later the term has also been used to refer to perceptions of Jobs's keynote speeches (or "Stevenotes") by observers and devoted users of Apple computers and products.
The RDF was said by Andy Hertzfeld to be Steve Jobs's ability to convince himself and others to believe almost anything with a mix of charm, charisma, bravado, hyperbole, marketing, appeasement and persistence. RDF was said to distort an audience's sense of proportion and scales of difficulties and made them believe that the task at hand was possible. Jobs could also use the RDF to appropriate other's ideas as his own, sometimes proposing an idea to its originator after dismissing it the week before.
The term is also used by Apple's competitors when they criticize Apple. On Research In Motion's official BlackBerry blog, Jim Balsillie introduced a blog post by saying "For those of us who live outside of Apple's distortion field".
Jobs's reality distortion field was parodied in Dilbert: Dilbert built a functioning reality distortion field emitter, which is used during Dogbert's keynote speech, while previous strips parodied iPhone flaws. In chapter three of the 2011 biography of Steve Jobs, titled Steve Jobs, biographer Walter Isaacson states that around 1972, while Jobs was attending Reed College, Robert Friedland "...taught Steve the reality distortion field..."
