摘要

Major terrorist events in the United States and Europe generate fear among the public and prompt swifter responses from public officials, reflecting a belief that terrorist attacks occur in clusters. If there is one attack, the concern is that others will soon follow. That presumption leads to two analytical questions: Does a significant terrorist attack somehow inspire other terrorist attacks, and can terrorist attacks be anticipated statistically? To answer these questions, RAND researchers examine the historical record of terrorism in the United States and Europe between 1970 and the end of 2013.

Using the Global Terrorism Database, the researchers find an absence of clustering for terrorist events around trigger events since 1994, no increases in terrorism on significant dates, and a decline of terrorism in the West since the 1970s, suggesting that the threat of terrorism should not affect individuals' behavior and decisions in the United States and Western Europe — not even in the wake of a significant terrorist event. However, heightened security may be justified. It may enable authorities to respond quickly to increased reports of suspicious activity and hoaxes that terrorist events inspire. Increased police presence also permits authorities to diagnose and intervene more rapidly if there are further incidents. Moreover, temporary security increases may be warranted as a precautionary measure, even if only to reassure an alarmed public that it is safe.
