Several recent commentaries have suggested possible researcher bias on the part of scientists conducting studies that find evidence of a causal link between violent video game play and aggression. The present article argues that patterns of authorship, publication, and research findings within the experimental violent video game-aggression literature are inconsistent with the researcher bias hypothesis. It is concluded that the claim of a causal link between violent video game play and aggression is a defensible interpretation of the current experimental and meta-analytic literatures.
