The Ruthlessometer

In the spirit of Halloween, here’s a fairly silly online quiz to determine how much of a psychopath you are (although I bet you already know!), on a polished but hilariously Mystery-esque website. The quiz is essentially an internet sidebar for a new book about the pros and cons of psychopathy, The Wisdom of Psychopaths: What Saints, Spies and Serial Killers Can Teach Us About Success, and which Smithsonian links to in its interview with the book’s author, “persuasion virtuoso” Kevin Dutton. (Video interview with Kevin here.)
