They test this proposition using a data base of 148 Palestinian suicide bombers from 2000-05. And they find that older and more educated suicide bombers are assigned to higher-profile targets, kill more people, and are less likely to fail or be caught. In short, there is a match between human capital, in this grossly distorted sense, and the desired goal.
And as for the bombers themselves, these authors argue that the bombers have made, what is for them, a rational choice: There is enough moral, psychological and sometimes financial payoff from the act of killing many people to offset the economic loss of their death. Therefore, the terrorist manager assigns the most deadly tasks to the highest-caliber people; otherwise, they will not bother. In an awful way, it makes sense, and it seems to be true. Caught and failed suicide bombers are conspicuously less educated than those who carry out their tasks.
