Abstract

The intelligence failure at Pearl Harbor is perhaps the most widely studied intelligence failure in American history. The lessons of that failure included the belief that warnings are invariably available before such a disaster, but missed, and that a major part of the solution is to improve the ability of analysis to find the key signals amid the background noise. These lessons have become conventional wisdom, and have been often reaffirmed since then, including after the 9/11 attacks and the Christmas Day 2009 airline bombing attempt. But this paper argues that the conventional wisdom about what went wrong with intelligence prior to Pearl Harbor is incorrect, and that this misconception has contributed to continuing intelligence failures today. This paper proposes a new model that better explains the failure of Pearl Harbor, and which can help improve intelligence performance today.
