A new study has claimed that Donald Trump has more psychopathic tendencies than Adolf Hitler.
Dr Kevin Dutton of Oxford University used the Psychopathic Personality Inventory – Revised (PPI-R) to assess and score world leaders based on eight traits, including stress immunity and cold-heartedness.
Dutton told the Independent:
Both great and terrible leaders score higher than the general population for psychopathic traits, but it is the mix of those traits that determines success.
We've created a (not entirely scientific) quiz based on the same eight traits. How much of a psychopath are you?
