Abstract
This article examines the application of ‘triangulation’ to the use of elite interviewing in political science, with specific reference to the study of the intelligence and security services. It is argued that the problems involved in using elite interviews in security and intelligence studies are no different than in other areas of political science, but simply more pronounced. It is further argued that these problems can be most effectively addressed in terms of the sociological ‘triangulation’ strategy of multi-methodological research. The article concludes that this approach is, moreover, generally applicable to political studies at large.
