Gamers Are More Aggressive To Strangers

TheClockworkSoul writes "According to NewScientist, victorious gamers enjoy a surge of testosterone — but only if their vanquished foe is a stranger. Interestingly, when male gamers beat friends in a shoot-em-up video game, their levels of the hormone plummeted. This suggests that multiplayer video games tap into the same mechanisms as warfare, where testosterone's effect on aggression is advantageous. Against a group of strangers — be it an opposing football team or an opposing army – there is little reason to hold back, so testosterone's effects on aggression offer an advantage. 'In a serious out-group competition you can kill all your rivals and you're better for it,' says David Geary, an evolutionary psychologist at the University of Missouri in Columbia, who led the study. However, when competing against friends or relatives to establish social hierarchy, annihilation doesn't make sense. 'You can't alienate your in-group partners, because you need them,' he says."

Re:Why do so many people...?

I guess that the OP simply thought this should be bleeding obvious to everyone, even without actually doing any research. The alternative/inverse would be that we are as likely to do harm to our beloved/friends as to a complete stranger, and that you "bond" tighter with friends than with strangers.

The Swedish king Karl XI has this figured out already in the 17th century when he organised his forces so that people would fight side-by-side with brothers, cousins and people from the same region as you are from. This improved morale and made people less likely to flee the battlefield as you knew you could depend on, and wanted to support loved ones.
