In 2015, the American Psychological Association (APA) released a task-force technical report on video-game violence with a concurrent resolution statement linking violent games to aggression but not violent crime. The task-force report has proven to be controversial; many scholars have criticized language implying conclusive evidence linking violent games to aggression as well as technical concerns regarding the meta-analysis that formed the basis of the technical report and resolution statement. In the current article, we attempt a reevaluation of the 2015 technical report meta-analysis. The intent of this reevaluation was to examine whether the data foundations behind the APA’s resolution on video-game violence were sound. Reproducing the original meta-analysis proved difficult because some studies were included that did not appear to have relevant data, and many other available studies were not included. The current analysis revealed negligible relationships between violent games and aggressive or prosocial behavior, small relationships with aggressive affect and cognitions, and stronger relationships with desensitization. However, effect sizes appeared to be elevated because of non-best-practices and researcher-expectancy effects, particularly for experimental studies. It is concluded that evidence warrants a more cautious interpretation of the effects of violent games on aggression than provided by the APA technical report or resolution statement.
