I don't believe a word she says. I've been playing videogames since I was a kid and I never had any impaired reasoning because of this. Now if you'll excuse me, I'm going to throw this penguin into the washing machine while the monkeys play the harpoon. Shpoople!
Seriously, though, I'm going to expect a wave of people just out right disagreeing with her claims for all of the wrong reasons. I do believe that games can cause some negative side effects, especially with children, but I've seen a lot of gamers ignoring that and just disowning said claims, saying that games are just being used as a scapegoat.
Granted, Dr. Goldacre seemed to have put the baroness in her place by saying that if it is a legitimate concern, she should present it in a more academically mature manner. Still, I predict lots of people just coming to this thread and complaining how games/gamers are being treated.
That, or lots of people wondering what the hell that picture is about. Seriously, Cavalli, what the crap?
