Concept.png Compartmentalisation Rdf-icon.png
An ancient technique of dividing information up between people to prevent the 'bigger picture' from being available to any of them.

Compartmentalisation is a divide and conquer technique in the area of information; project secrecy is promoted by strict segregation of the available information.

Hypothetical example

An abstract example may help illustrate the effectiveness; a project to carry out an incriminating event (represented in the abstract by the phrase "false flag") can be broken down into smaller pieces (e.g. "f", "a", "l", "s", "e", " ", "f", "l", "a", "g"), each of which is necessary but none of which on their own yields any insight into the meaning of the operation. So, in the real world, one team could prepare some explosives, another team could drive an unknown substance somewhere, a third team could send someone an encrypted invitation and so on. In this way, hierarchies of people can be organised, complex plans and subplans enacted without those involved being aware of what they are really doing.

Real life example

Richard Lambert is the FBI agent who headed the FBI's "investigation" into the Amerithrax case from 2002 to 2006. In a 2018 interview for the Opperman Report he stated that the investigation was extremely compartmentalised. He reports that he was told that this was an effort to prevent leaks about its progress. When challenged about the leaks, he invited his superiors to take a polygraph test with him but they declined.[1]


The fundamental principle is that information is given only on a need-to-know basis.


Information sharing between operatives, for example due to poor design or lax implementation of compartmentalisation can overcome the technique, allowing those involved to see the bigger picture.

Sibel Edmonds joined the FBI after 9-11 when they were very short of translators for Turkish languages. This lack of staff hindered compartmentalisation. She has testified how compartmentalisation prevented agents on the ground from forming a bigger picture of the intrigues they were involved in, but that she, as a translator, was better positioned to get an overview:

“The most important thing for people to get is we're not even looking at one big investigation, all these agents working together. They were chopped up and divided, but because I worked in the central place... other agents were sending their material to me... I was in this position to see all the dots being connected... These agents, while I was there, because I was the central person, they started connecting the dots.”
Sibel Edmonds [2]
