Hans Reiser is a former SF Bay Area technology executive now serving 15 years for second-degree murder, after he accepted a plea bargain and led police to his wife's body.
Why I bring this up is that Reiser, who certainly seems to have a couple fried circuits, wants to appeal his conviction, in part because he thinks his attorney didn't represent him properly. According to Henry K. Lee's San Francisco Chronicle News Blog, Reiser says his attorney, William Du Bois, exhibits symptoms of oxytocin excess. To wit, he enjoys betraying others.
This is based on something Paul Zak of Claremont Graduate University's Neuroeconomics Dept. has found: A few people in his studies show very high levels of oxytocin in their blood, and yet instead of being cooperators, they seem to get a charge out of screwing the other person in the economic games they play in Zak's studies.
Nevertheless ... Come on, dude! Get a grip.
