Tanya Lewis in Scientific American:
The violent insurrection at the U.S. Capitol Building last week, incited by President Donald Trump, serves as the grimmest moment in one of the darkest chapters in the nation’s history. Yet the rioters’ actions—and Trump’s own role in, and response to, them—come as little surprise to many, particularly those who have been studying the president’s mental fitness and the psychology of his most ardent followers since he took office. One such person is Bandy X. Lee, a forensic psychiatrist and president of the World Mental Health Coalition.
…What attracts people to Trump? What is their animus or driving force?
The reasons are multiple and varied, but in my recent public-service book, Profile of a Nation, I have outlined two major emotional drives: narcissistic symbiosis and shared psychosis. Narcissistic symbiosis refers to the developmental wounds that make the leader-follower relationship magnetically attractive. The leader, hungry for adulation to compensate for an inner lack of self-worth, projects grandiose omnipotence—while the followers, rendered needy by societal stress or developmental injury, yearn for a parental figure. When such wounded individuals are given positions of power, they arouse similar pathology in the population that creates a “lock and key” relationship.
“Shared psychosis”—which is also called “folie à millions” [“madness for millions”] when occurring at the national level or “induced delusions”—refers to the infectiousness of severe symptoms that goes beyond ordinary group psychology. When a highly symptomatic individual is placed in an influential position, the person’s symptoms can spread through the population through emotional bonds, heightening existing pathologies and inducing delusions, paranoia and propensity for violence—even in previously healthy individuals. The treatment is removal of exposure.
