Intelligence Failures

Vak
2025-2026

Admission requirements

This course is designed for the minor Intelligence Studies. It is not possible to follow single courses of this minor. You need to be enrolled in uSis for the minor to be accepted to this course. There are 100 places open for registration, on a first come first serve basis, where LDE students are given priority.

Description

Over the past thirty years, the so-called intelligence revolution that occurred during the Second World War and Cold War became a core concern in the academic literature and in intelligence studies programmes. Among the aspects that feature prominently in those debates are post-mortem evaluations of crisis preparedness and the notion of intelligence failure. Whereas from the point of the intelligence community successful intelligence operations should remain secret as long as necessary, allegations of failure tend to be publicly discussed and actual failures come out into the open. These instances are often subject to national inquiries, producing much relevant material for academic scrutiny. Some of these failures have become national traumas, such as the failure to act on available information about an impending Japanese attack on the U.S. Pacific Fleet at Pearl Harbor or the 9/11 attacks.

In this course, in addition to exploring various cases of intelligence failure (or alleged failure), students will be introduced to conceptual discussions, theoretical expectations and methodological aspects. They will engage with the question of how effective warnings could have been issued in specific situations. Students will also be encouraged to reconstruct the idiosyncratic context in which intelligence producers and policymakers interacted when confronted with a given crisis. They will apply their knowledge in a group exercise in which they unpack a specific failure, as well as in the final exam. The cases covered in this course include well-known historical failures in the U.S. context, recent cases of relevance to European foreign policy as well as non-Western cases.

Course objectives

Upon finishing the course, students will be able to:
1. understand the core concepts and debates around intelligence success versus failure;
2. identify and explain different biases and other constraints when producing intelligence;
3. understand specific challenges in the intelligence-policy interplay for the cases covered;
4. discuss various examples of intelligence failures;
5. identify the different aspects of a ‘warning failure’;
8. produce a warning report;
9. select and work with the relevant literature for the assignments.

Timetable

On the right side of the programme front page you will find links to the website and timetables, uSis and Brightspace.

Mode of instruction

The course will consist of seven 3-hour sessions, which will be taught by the course convenor and guest lecturers. Each of the sessions will include interactive lectures and discussion of the core reading and/or other relevant material that will be shared ahead of class. In-class formative assignments might also be held to help students prepare for the assigments.

Participation in each session as well as in the group exercise and final exam is required in order to obtain a grade. One session may be missed.

Assessment method

Midterm group exercise

  • 30% of final grade

  • Resit not possible

  • Grade must be compensated

Final exam

  • 70% of final grade

  • Grade must be 5.50 or higher to pass the course

  • Resit possible

  • Resit will take the same form

Participation in each session as well as in the group exercise and final exam is required in order to obtain a grade. One session may be missed.

Students will also be permitted to resit the 70% final exam if they have a calculated overall course grade lower than 5.50 or with permission of the Board of Examiners. The midterm group exercise needs to be compensated.

The corresponding Brightspace course will become available one week prior to the first session. Details for submitting the assignments will also be posted there.

Late hand-in penalty: 1 point minus per day, and after three days we do not accept the assignment any longer.

In the case of written assessment methods, the examiner can always initiate a follow-up conversation with the student to establish whether the learning objectives have been met.

The Course and Examination Regulation Security Studies and the Rules and Regulation of the Board of Examiners of the Institute of Security and Global Affairs apply.
