Jennifer Lawrence thinks about "pushing people on the tracks" when she rides the subway.
The 27-year-old actress made the bizarre confession while taking a lie detector test for Vanity Fair magazine, during which she was forced to make a decision over redirecting a speeding train so that it only hit one person or leave it and allow it to plough into a group of 20 people.
Although Jennifer said she would pull the bar, she then went on to admit that she's thought of pushing a person in front of the train - even though she'd never do it.
She explained: "I mean It would be psychotic not to. In fact, every time I am in the subway, I always think about pushing people on the tracks. I don't do it. I don't get tempted to do it, but it crosses my mind," before she looked at the lie detector results for confirmation.
She added: "Told you. I am so happy it was confirmed by a polygraph that I'm a psychopath. I don't want to do it."
