Judith Lewis Herman of Harvard Medical School and Bandy X. Lee of the Yale School of Medicine wrote in the prologue: “Anyone as mentally unstable as Mr. Trump simply should not be entrusted with the life-and-death powers of the presidency.”
Philip Zimbardo, who ran the famous Stanford prison experiment, added that Trump is “an impulsive, immature, incompetent person who, when in the position of ultimate power, easily slides into the role of the tyrant.”
Retired Harvard psychiatry professor Lance Dodes said: “Mr. Trump’s sociopathic characteristics are undeniable.
“They create a profound danger for America’s democracy and safety. Over time these characteristics will only become worse, either because Mr Trump will succeed in gaining more power and more grandiosity with less grasp on reality, or because he will engender more criticism producing more paranoia, more lies, and more enraged destruction.”
Not all of the co-authors of the book agreed, however.
Clinical psychologist Craig Malkin said: “Equating mental illness with incapacity merely stigmatizes the mentally ill.”
He went on to suggest that Trump did show signs of “extreme present hedonism.”
