In The Dangerous Case of Donald Trump by Bandy Lee, mental health experts argue that, in Trump’s case, their moral and civic “duty to warn” America supersedes professional neutrality. Philip Zimbardo and Rosemary Sword, for instance, explain Trump’s impulsivity in terms of unbridled and extreme present hedonism. Craig Malkin writes on pathological narcissism. Gail Sheehy, on a lack of trust that exceeds paranoia. Lance Dodes, explores sociopathy. And Robert Jay Lifton, writes on the “malignant normality” that can set in everyday life if psychiatrists do not speak up.
