When The Shot Backfires: How Motivated Reasoning Leads to Beliefs That Oppose Scientific Evidence

We examined how scientific research on a popular topic influences the beliefs of those most invested in the research. We focused on violent video game (VVG) research and VVG players. We tested the hypothesis that non-players would update their beliefs based on the study conclusions, whereas players would not. Participants read abstracts with either a positive effect or a null effect. Study 1 (N = 788) used real article abstracts, while Study 2 (N = 788) used standardized fictional articles. Beliefs about the effect of VVGs on aggression were measured before and after reading. Results in both studies showed that at low VVG exposure, participants in both conditions updated their beliefs to align with the research. However, at high VVG exposure, participants maintained their belief that VVGs do not increase aggression, and at very high exposure levels, positive-effect studies led participants to believe the opposite: that VVGs reduce aggression.
