Behaviour and Information Technology recently published a new study by Vivian Hsueh-Hua Chen and Yuehua Wu titled, “Group identification as a mediator of the effect of players’ anonymity on cheating in online games”. This study looked in to how other players might effect whether a player cheats or not based on the stance of that particular group.
It essentially says that while players are likely to cheat when anonymous, they are also very likely to do so if they belong to a social group made up of cheaters. It all seems pretty obvious, however these people have to fill the time with something right? If you have nothing better to do than play pseudoscience with Captain Obvious, read the full study.
