"This is a trait shared by entrepreneurs, engineers, and extremists. There's a high overlap between the three."

Are management-level terrorists coming from former entrepreneurs? None of the top people in al-Queda were engineers. Bin Laden did come from a family that runs a huge construction company, but he himself never did anything in that area. Within ISIS, many of the top people were either career military or religious. Shaker Wahib al-Fahdawi al-Dulaimi was a computer science student, though.
