In this article, I learned,<p>* that the "warrior gene" thing == psychopathy,<p>* that your genes determine your personality, except when they don't,<p>* that your behavior is determined by your biology, except when it isn't,<p>* that lack of affect == Buddhism,<p>* that "looking at brainscans" is a valid step in judicial sentencing,<p>* that you can claim to be a person who suffers from an impairment of empathy, who at the extreme, might well not see the difference between a person and a block of wood, and <i>still</i> be taken seriously when you say "that genetics were very, very dominant in who people are—that your genes would tell you who you were going to be",<p>* that neuroscientists aren't all that spectacular about keeping their data sets neat and orderly; in particular, they don't see a big deal mingling the results of several different experiments, and<p>* that claiming to have a Big Evil background, that you have to struggle with every day, is <i>still</i> a great way to get publicity.<p>I laughed, I cried, it changed my life. Two thumbs up.<p>By the way, have I mentioned that I am of somewhat Nordic descent; every day, I have to fight off the urge to raid the coastlines of Europe, to pillage and plunder the tender and peaceful farmsteads and towns?
