The 27-year-old actress - who dated Sean Penn for five months this year after her marriage to Ryan Reynolds ended last December - likes men who challenge authority and are adventurous, but she doesn`t care how they are perceived by other people.
She said: "I`m attracted to the quality of being adventurous and perhaps a bit mischievous. And also questioning authority and being proactive.
"If that makes up a quintessential bad boy, then whatever."
While she likes bad boys, Scarlett insists she won`t tolerate nastiness or bullying behaviour.
She added in an interview with America`s Cosmopolitan magazine: "I`m not at all attracted to meanness or bullying.
"I do think conviction is attractive. I mean, really, who doesn`t?"
As well as dating Sean, the `We Bought a Zoo` actress has been romantically linked with stars including Bradley Cooper, Justin Bartha and Joseph Gordon-Levitt since she split from Ryan, but the `Green Lantern` actor recently admitted he has not found it easy to move on.
He said: "Anyone who gets divorced goes through a lot of pain but you come out of it.
"I`m not out of it yet, at all. I don`t think I want to get married again."
