The podcast Dead Pixel Live interviewed Dr. Patrick Markey from Villanova University, the man behind a number of studies on violence in videogames and its effect on people. They cut through all the big science words and graphs and asked some fundamental questions. Like, 'Will I kill people after I finish Gears Of War?' And the answer isn't as clear cut as you may think. Some people actually do get more aggressive after playing Manhunt.
The interview starts about 1 hour into the show and lasts about 45 minutes.
