Sigh....a nice clinical description of our recently departed president...Owen and Davidson offer a study of US presidents and UK prime ministers over the past 100 years. Here are a few clips:
We believe that extreme hubristic behaviour is a syndrome, constituting a cluster of features (‘symptoms’) evoked by a specific trigger (power), and usually remitting when power fades. ‘Hubris syndrome’ is seen as an acquired condition, and therefore different from most personality disorders which are traditionally seen as persistent throughout adulthood. The key concept is that hubris syndrome is a disorder of the possession of power, particularly power which has been associated with overwhelming success, held for a period of years and with minimal constraint on the leader.Owen and Davidson define hubris syndrome:
The ability to make swift decisions, sometimes based on little evidence, is of particular importance—arguably necessary—in a leader. Similarly, a thin-skinned person will not be able to stand the process of public scrutiny, attacks by opponents and back-stabbings from within, without some form of self-exultation and grand belief about their own mission and importance. Powerful leaders are a highly selected sample and many criteria of any syndrome based on hubris are those behaviours by which they are probably selected—they make up the pores of the filter through which such individuals must pass to achieve high office.
...as a pattern of behaviour in a person who: (i) sees the world as a place for self-glorification through the use of power; (ii) has a tendency to take action primarily to enhance personal image; (iii) shows disproportionate concern for image and presentation; (iv) exhibits messianic zeal and exaltation in speech; (v) conflates self with nation or organization; (vi) uses the royal ‘we’ in conversation; (vii) shows excessive self-confidence; (viii) manifestly has contempt for others; (ix) shows accountability only to a higher court (history or God); (x) displays unshakeable belief that they will be vindicated in that court; (xi) loses contact with reality; (xii) resorts to restlessness, recklessness and impulsive actions; (xiii) allows moral rectitude to obviate consideration of practicality, cost or outcome; and (xiv) displays incompetence with disregard for nuts and bolts of policy making.
