Counterterrorism strategies in the lab

摘要

We conduct experiments to test the collective action dilemmas associated with defensive and proactive countertenor strategies. Defensive policies are associated with creating public 'bads' (e.g., a commons) whereas proactive policies are akin to the voluntary provision of public goods. When combined, the inefficiency of collective action is exacerbated, resulting in a situation known as a Prisoner's Dilemma squared (PD2). Deterministic versus probabilistic equivalent versions of the associated externalities are compared within a laboratory setting. Experimental results reveal that the collective action problem associated with counterterror strategies is deepened in uncertain environments, and is indeed a robust regularity that is not easily overcome; as individuals gain more experience, they become even more self-interested.
