US presidential hopeful Donald Trump has more psychopathic traits than Adolf Hitler, a researcher at Oxford University has found.
Psychologist Dr. Kevin Dutton has ranked the psychopathic traits of the Republican candidate and various historical figures using a standard psychometric tool the Psychopathic Personality Inventory Revised (PPI-R).
Experts suggested likely scores against a series of questions. Trump scored 171, two points more than Hitler.
Saddam Hussein topped the list, scoring 189, while Democratic presidential hopeful Hillary Clinton received a score of 152, putting her in the top 20 percent.
