Trump a bigger psychopath than Hitler, new study says
US presidential candidate Donald Trump possesses stronger psychopathic tendencies than Adolf Hitler, a study suggests.
Research from the University of Oxford assessed this year's candidates for the White House to determine how highly they ranked on the psychopath scale.
They were scored on a number of personality traits typical in psychopaths, including fearlessness, cold-heartedness and egocentricity.
While the study found Donald Trump's score puts him in the company of some of history's greatest despots, including Hitler and Ugandan dictator Idi Amin, his opponent Hillary Clinton found herself alongside Napoleon Bonaparte and Emperor Nero.
Mr Trump outstripped Hitler on factors including social influence and fearlessness, while the genocidal Nazi dictator scored higher on "Machiavellian egocentricity" and cold-heartedness.
While ranking lower than her rival overall, Mrs Clinton far exceeded tyrannical Roman emperor Nero on traits such as "Machiavellian egocentricity".
One characteristic typical in strong leadership was fearless dominance - an area in which Mr Trump scored very highly.
The findings, published in the journal Scientific American Mind, found that another high-scoring area for the billionaire businessman, self-centred impulsivity, could undermine this, however.
The study contended that although psychopathy - typically associated with remorseless killers - exists along a spectrum, some people can possess certain qualities without developing murderous intent.
It claimed that it was not just barbarous leaders who populated the upper echelons of the rankings - as Saint Paul and even Jesus appeared high on the psychopathic leaderboard.
