Heard of the Rashomon effect?
It is a term related to the unreliability of eyewitnesses. It describes a situation in which an event is given contradictory interpretations or descriptions by the individuals involved.
The effect is named after Akira Kurosawa’s 1950 film by the same name ― Rashomon. The story revolves around a murder described in four subjective, alternative, self-serving, and contradictory ways by four witnesses.
Each of the characters relate the incidents as a contradiction of the other, but they describe them in such a convincing manner that the audience tends to believe them all.
