A new book blames videogames and pornography for the “demise” of men.

The Demise of Guys: Why Boys Are Struggling and What We Can Do About It by Dr. Philip Zimbardo and Nikita Duncan cited “arousal addiction” as the reason boys were underperforming at school, were five times more likely to be diagnosed with Attention Deficit Hyperactivity Disorder, and were failing in relationships.

The addiction, a situation where the addict craved new experiences, was in part due to excessive videogaming, claimed the text.

Pornography and the Internet were also cited as contributing factors.

"Technology is not the issue. Rather, it's the misuse of technology. There's a general overuse of videogames and porn – especially in social isolation – which is not balanced out by other activities like exercise, face-to-face socialisation with peers, or individual time with any kind of male mentor," said Duncan.

“Every year there is research done on self-reported shyness among college students and we’re seeing a steady increase in males,” said Zimbardo.

“They don’t know what to say, they don’t know what to do, especially one-on-one with the opposite sex.

“It turns out from earliest childhood, boys and then men prefer the company of guys.”

The problem is that men now preferred the Internet over spontaneous interaction in social relationships, he said.

“Boys brains are being digitally rewired in a totally new way for change, novelty, excitement and constant arousal, which means they are totally out of sync in traditional classes which are analogue, static and passive."

Dr. Zimbardo and Duncan cited the death of Seungseob Lee after 50 continuous hours of playing StarCraft, as well as mass murderer Anders Behring Breivik’s admission that he played Call of Duty and World of Warcraft as further proof of this phenomenon.
