Originally described in Crichton's "Why Speculate?" speech, the Gell-Mann amnesia effect labels a commonly observed problem in modern media, where one will believe everything they read from a journalist even after they come across an article about something they know well that is completely incorrect.
The conclusions found and perspectives portrayed by the author are entirely erroneous, often times flipping the cause and the effect. Crichton notes these as "wet streets cause rain" stories.
In short, most eloquently put by Thomas L. McDonald, the Gell-Mann amnesia effect defines the idea that "I believe everything the media tells me except for anything for which I have direct personal knowledge, which they always get wrong."’
