Intelligence gathering post-9/11.

Abstract

The gathering of information for intelligence purposes often comes from interviewing a variety of individuals. Some, like suspects and captured prisoners, are individuals for whom the stakes are especially high and who might not be particularly cooperative. But information is also gathered from myriad individuals who have relevant facts to provide, and occasionally the smallest details can be important. In gathering this information from both groups of informants, investigators need to worry about memory distortion, especially the extent to which memories can be contaminated by poor questioning or other sources of postevent information. Moreover, they need to worry about the potential for poor methods and other forms of influence to create false confessions, thereby leading investigators astray. A third area in which psychological science can contribute is in the detection of deception. Recent science in these domains can improve the quality of information that investigators gather and the inferences that they draw.
