Information Research, Analysis, and Reporting


The focus of this web-page is on source evaluation, critical thinking, analytic methods and analytic processes. All of the methods discussed here can be found in public sources. Although these methods and processes are taken from many fields such as cognitive science, statistics, and business management, they are also useful for making sense of incomplete information, and forecasting.


As of May 2008: I am a curriculum manager at the National Cryptologic School, and have a BS in Government and Politics from the University of Maryland University College, and a MS in Strategic Intelligence from the Joint Military Intelligence College. I have worked in intelligence since 1983. The views expressed here are mine and do not reflect the official policy of, or position of the Department of Defense or the U.S. Government.
