1) It has nothing to do with technical abilities. Terrorists don't attempt to recruit people by technical ability, they just take whoever they can get.
2) It has nothing to do with ease of immigration as a skilled migrant. The paper cites studies on American religious terrorists (the nominally Christian far-right) and concludes that the unusual tendency of engineers towards right-wing radicalism seems universal.
3) The paper argues that the 'styles of thinking' that predispose people towards engineering, also predispose them towards right-wing radicalism. Engineers are more reliably right-wing than even economists! (who are the second-most reliably right-wing academic group). Likewise, a liberal arts education is correlated with left-wing radicalism (e.g., communist bombing campaigns in postwar Western Europe). But there have been relatively few left-wing bombing terrorist acts after the end of the Soviet Union, while right-wing radicalism is on the rise. Hence mad engineers rather than mad Marx-spewing liberal arts graduates.
