TY - CHAP AB - Abstract In this chapter, I analyze the decision calculus of President Donald Trump, using the Applied Decision Analysis (ADA) method (Mintz, 2005, Mintz & DeRouen, 2010). I analyze seven foreign policy decisions taken in the first six months of Trump’s presidency. I find that in his decision-making process, President Trump applies six dimensions. My analysis reveals that the imagery dimension has affected President Trump’s decisions across the board, and led to the rejection of non-compensatory alternatives. Based on my research, I conclude that President Trump demonstrated a poliheuristic decision code. Furthermore, from my analysis derives that President Trump’s decision-making process is mostly intuitive. Moreover, this chapter reveals a polythink syndrome in Trump’s decision unit, manifested in the battle between his two groups of advisors, known as the nationalists and globalists.
