Why do you believe that?

Wow. that's a great premise for one of those TV crime shows. Wonder why they haven't used it. Because it's a load of crap, that's why.
Think you have have much better internet than me. Have a look before you coment. Jim
Baseless accusation.... Classic response by someone without a response. I'll take it as the best concession of defeat you could come up with.
There you go MrG and guess which races rate high. Sure you can prove it wrong, by saying it's a load of crap, as I do believe you do know a lot about crap. Jim

HIGH TESTOSTERONE, LOW SEROTONIN:
DOUBLE TROUBLE?


Studies link high levels of the male hormone testosterone to aggression-but elevated testosterone alone doesn't account for aggressive behavior. In fact, successful athletes and businessmen tend to have high testosterone levels, without being any more violence-prone than their low-testosterone counterparts.
Paul C. Bernhardt suggests that testosterone may not act alone in promoting aggression. Rather, he suggests, aggressive men's behavior may be influenced by high testosterone levels combined with low levels of the brain chemical serotonin.
Bernhardt notes that testosterone is linked more strongly to dominance in general than to aggression. But what happens, he asks, when a high-testosterone man is frustrated in his attempts to achieve dominance? Then, Bernhardt speculates, serotonin comes into play, because low serotonin activity is associated with hyperresponsiveness to aversive stimuli.
In short, Bernhardt theorizes, high testosterone levels encourage dominance-seeking behaviors, "which put the individual into situations in which frustration of dominance can occur." When this happens, low serotonin levels result in a greater likelihood of an intensely negative emotional reaction, and, thus, a greater chance of aggressive behavior.
Bernhardt speculates that the hypothalamus and amygdala, "prominently associated with both testosterone and serotonin," play a key role in aggressive responses to situations in which efforts at dominance are frustrated. He notes that "low serotonin levels have been found in the hypothalamus and the amygdala in aggressive animals," and that "testosterone action in both of these brain structures has been shown to increase aggression in various animal species."

Bernhardt, Current Directions in Psychological Science, Vol. 6, No. 2, April 1997, pp. 44-48. Address: Paul C.
