ISIS, Hip-Hop Jihadists and the Man Who Killed James Foley
Anthropologist Scott Atran, who is frequently consulted by the U.S. government, has long argued that a jihadist’s motivations cannot be fit within a purely rational framework of costs and benefits, nor can they be understood as utterly irrational. Instead they work within the context of what they come to see as “sacred values,” which may be religious, or may have to do more with honor and respect and, perhaps, what the 18th-century political theorist Edmund Burke called “the sublime”: that “quest for greatness, glory, eternal meaning in an inherently chaotic world,” as Atran says.

“It seems like volunteers for ISIS are surfing for the sublime,” Atran wrote to me on Sunday. They are escaping “the jaded, tired world of democratic liberalism, especially on the margins where Europe’s immigrants mostly live.”
Not everything is governance, religion, or any of the other areas myopic theorists focus on, sometimes is just simple human psychology.
