Lots of mostly low grade "debate" too.The National Science Foundation conducted a study that confirmed what social psychologists have shown before: it's the group with which a person identifies, not individual personality, that often determines behavior. From WSJ, Alternative Peer Groups May OfferWay to Deter Some Suicide Bombers
That realization is shaping scientists' understanding of suicide bombers, whose numbers have soared. Who are they? Not the cowardly psychopaths or sociopaths you might expect. "There is little to no evidence that they are mentally unbalanced," says Todd Stewart, a retired Air Force general who now directs the Program for International and Homeland Security at Ohio State University. From the Sept. 11 attackers to Palestinian suicide bombers to al Qaeda terrorists, they are educated, fairly well off and "not necessarily from fanatically religious families," he says.
This alarmingly normal profile is why the National Science Foundation gave anthropologist Scott Atran, a research director at the National Center for Scientific Research, Paris, emergency funding to study groups that sponsor suicide attacks. He just spent three weeks in Gaza and the West Bank, where he spoke to counterterrorism strategists, fugitive Hamas leaders, would-be suicide bombers and families of "martyrs."
"None of the supporters of suicide terrorism I interviewed, especially at al-Najah University, were poor, uneducated, socially estranged or psychologically deranged," says Prof. Atran. "They are idealistic and compassionate, and think they can change the world. That makes the whole thing more frightening than if they were just crazies off the street." In a study of al Qaeda recruits, forensic psychiatrist Marc Sageman of the University of Pennsylvania finds a similar pattern: Many attended college and are economically better off than most Palestinians or European Muslims, and they are often "the elite of their countries," he says.
