1. ‣Stability and Change in Belief Systems: The Operational Code of George W. Bush from Governor to Second Term President” Journal of Conflict Resolution 52 no. 8 (2008): 820-849. 

Cognitive frameworks and belief systems are the primary lenses through which presidents view the world. Two important questions are whether these beliefs ever change significantly, and if so, what causes these changes?  This paper develops empirical data on the strategic and operational beliefs of President George W. Bush as a means of examining the theoretical basis for how and why core beliefs change.   The author analyzes the foreign policy operational code of President Bush in four separate phases of his political career: the immediate pre-presidential phase; his nine months in office prior to September 11th, 2001; the six months immediately following the 9/11 terrorist attacks; and his last year in office as a second-term president.  The results of this article allow us to address several recurring questions that concern the Bush administration, and presidents’ belief systems and decision-making. They challenge traditional interpretations of the Bush presidency and provide some insights into the causal mechanisms that underlie belief change.
