The 20% that the UN receives today is based on UN input associated with our creation of the Class Before One Briefing, the UN slide as provided to Robert Steele can be found therein.

The original conceptual depictions of “competing influences” on individual decision-makers were first developed by Dr. Greg Treverton teaching the Intelligence Policy Seminar at JIF School of Government, and Jack Davis, dean of the U.S. Intelligence Community scholar-analysts. The “eight tribes” (previously seven) are original to Robert Steele. Steele's adaptation of Davis-Treverton first appeared as Figure 17 on page 53 of ON INTELLIGENCE: Spies and Secrecy in an Open World (AFCEA, 2000).
