In the meantime, hardly anyone believes that Donald Trump will give up his bizarre behavior in the course of his presidency and become accessible to rational thinking. 27 American psychiatrists, psychologists and therapists explain why someone like Trump is absolutely unfit for office and should never have been entrusted with the power of the American president. In doing so, they are breaking an important ethical rule of their profession, which prohibits them from attesting to a mental or mental illness to public figures, i.e. from making a remote diagnosis without a prior diagnostic examination. They see the reason for the decision to give up their professional neutrality in their 'duty to warn the public'. In exciting articles, the authors examine Trump's narcissistic traits, psychopathological symptoms and bizarre actions, which, given his abundance of power, actually pose an acute danger not only to the USA, but to the whole world.
