Trump’s Cognition and His Unorthodox Foreign Policy Approach

In many aspects, U.S. President Donald Trump’s approach to foreign policymaking was in sharp contrast with that of his predecessors, particularly post- WWII presidents. His hostility toward the long-lasting liberal international order that was crafted and maintained by former presidents, his eccentric ways of solving foreign policy issues, and his unusual rhetoric regarding U.S. allies and adversaries, are all indications of his “unorthodox” foreign policy approach. In an attempt to explain this unorthodoxy, in this article we aim to examine Trump’s cognitions and compare them to those of his post-WWII predecessors. In particular, we have measured the cognitive complexity score for each of these presidents to determine Trump’s position among them. In order to do so, we have calculated the Flesch-Kincaid readability score of the presidents’ verbal statements, assuming that the complexity of the statements indicates the complexity of their author’s thoughts. The results have clearly demonstrated that Trump was at the lowest level of cognitive complexity among the presidents under examination, and since a low level of cognitive complexity pertains to viewing the situation from limited perspectives, a low need for broader information, adhering to a limited number of policy options, ignoring advice, and decisiveness, we may reasonably infer that his cognitive simplicity played an important role in the unorthodoxy of his foreign policy approach.
