I know from personal experience that it's true! How perceived realism in video games and television series may affect real-world beliefs.

Abstract

From the idea that a narrative can be absorbing, bring about a transporting experience, make the spectator identify with characters and in turn experience the narrative as realistic comes our main hypothesis that perceived realism can affect real-world beliefs. We subjected our 70 participants to a questionnaire exploring this and two supporting hypotheses, making use of the individual's memories of a favourite series or video game. We then explored our results using multiple regression and came to mixed yet interesting and revealing conclusions, both for our hypotheses and as well for the mediumspecifc aspects of the process we propose.
