Does Trump Fit the Evolutionary Role of Narcissistic Sociopath? Nathan H. Lents and Robert Trivers There is no shortage of published psychological profiles of Donald J. Trump that attempt to diagnose him, from a distance, as either a psychopath or a narcissistic sociopath. These profiles, of course, are fatally hindered by the lack of access to Mr. Trump for personal examination and completion of personality inventories. However, exploration of the evolutionary features of these very peculiar personality types may provide insight into this important question. Psychopaths are indeed an evolutionary conundrum because their particular behaviors are not an obvious path toward evolutionary success. For example, the majority of serial killers are childless when they are killed or apprehended. Narcissistic sociopaths, however, invariably [typically] have families and children whom they support energetically, and many of the traits specific to this phenotype can fairly be called adaptive. This raises the important issue of the evolutionary niche of a narcissistic sociopath within the societies in which they exist.
