Scientists' Mouse Fight Club

An anonymous reader writes "To study how aggression, fighting, and winning change the brain, scientists set up a tournament of mice fights. They watched as the lab rodents took a break from their hum-drum existence and battled it out (however, the researchers broke the first rule of Fight Club by publishing a paper about their findings [abstract]). They found clear evidence of the 'winner effect,' in which a mouse that has just won a fight maintains elevated levels of testosterone and aggression, and is therefore more likely to win the next bout. Interestingly, the winner effect was strongest in mice that were fighting in their own cages — i.e., those that had home-field advantage."

    Female aggression only happens when women are empowered. I guess we should disenfranchise them again. (That's a joke, son.)

    But more seriously, when people are given the latitude to be aggressive, you'll see a spectrum of responses. Some people can handle power responsibly, others get drunk with it and start thumping people with little provocation or cause. Systems are supposed to be designed such that abusers are culled, but it seems that just as frequently a given system of authority closes ranks and defends 'it's own' against outside accusations however well-founded.

    However there's no cause to single out genders/races/ages/etc. because such categories only go so far in explaining what are ultimately individual motivations. People may draw from various behavior archetypes, may respond to various experiences in ways that can be predicted or categorized, but there are always factors that introduce variances such that you can't view people as simple equations of A + B = C every time.

There two provocative books on the subject by Christina Hoff Sommers Who Stole Feminism?: How Women Have Betrayed Women and The WAR AGAINST BOYS: How Misguided Feminism Is Harming Our Young Men.

    That said, I heard a very interesting talk by an old martial arts master (I forget which, one of the japanese schools) in a documentary. His insight on schoolyard violene was interesting... he said its good for boys to fight when they are young because they learn their own strength, they get hurt, and they learn how much damage they can do to others and themselves.

    His claim was that the danger of trying to eliminate this sort of fighting was young adults growing up not knowing their own strength and not being as aware of how much they can hurt each other, and so fights between them, when they do arise, are more deadly.

    Overall, I believe it. Look at someone whose been a martial artist for years. The control that they can exhibit is amazing. The ability to throw a "lightning fast" punch, yet connect with so little force that you might not know it, or how and where to give you a good solid hit to bruise your ego without damaging your bones or flesh. Hell, one of my instructors had so much control, that I didn't realize that he was demonstrating a sneaky groin kick until I felt his toes caressing my balls. Quite unsettling how fast it happened but... he still had enough control to not even cause pain.

    Now schoolyard fights wont give you that sort of control but... try sparring with some new students who just recently learned how to throw a kick and its just all unfocused power with no control.... so I can definitely see it.
