In a review of Engineers of Jihad: The Curious Connection between Extremism and Education, by Diego Gambetta and Steffen Hertog, Ursula Lindsey writes: The second argument advanced by the authors to explain the “strange correlation” between studying engineering and joining a jihadist group is based on a comparative study of the political affinities of the members of radical left- and right-wing groups in the West. It shows that engineers are overrepresented among right-wing radicals generally (while humanities and social science students are more abundant among left-wing militants).

The authors suggest that Islamist and right-wing militants share a number of personality traits that have been shown to be associated with political conservatism. These include a propensity to feel disgust; a strong identification with an “in-group” and hostility toward those who don’t belong to it; and a discomfort with ambiguity and open-ended discussions (known in the literature as a “need for closure”). In Islamist circles, the authors write, “proneness to disgust is related to the strong reaction to perceived corruption of customs and a desire for social and sexual purity. In-group bias is related to a marked aversion for those who are different, be they immigrants, ethnic others, or infidels. The most multifaceted of these traits, need for closure (NFC), is related to a strong preference for hierarchy and social order and an aversion to change, which can reach the extreme of longing for a mythical past.”

Because of these underlying affinities, the authors speculate, some individuals may be “attracted to engineering as a discipline that provides concrete, unambiguous answers, and recoil from the open-ended project of natural science and the ambiguities of the humanities and social sciences.” Engineering students, “like followers of text-based religions, rely more strongly on answers that have already been given.” [Continue reading…]
