In the last 12 months, controversy around video games and violence has reared its head again with some authorities proposing a tax on violent video games. Yet a new scientific study from Oxford University's Internet Institute has found no link between the violent video games and teenage aggression. It joins a long list of studies that have struggled to find a connection, but this is the most definitive study to date and addresses some of the issues of previous studies.As explored by GamesIndustry.biz's Haydn Taylor , the report stands out because this isn't just a convenient perspective on general research data — it's a dedicated study that set out to test the link in its hypothesis. The approach, in which the intentions of the study have to be registered before research begins, mitigates against researcher bias in interpreting the results.You can explore the results for yourself by reading the published research , but without getting technical there was simply no conclusive evidence between violent video games and increased aggression in the 2,000 British 14 and 15 year olds taking part in the study. The researchers conceded that games can provoke "some angry feelings or reactions", but that's a considerably different take-away than the idea that the video game itself is conditioning the player towards violence.What do you think of this latest report?
