If you've ever wondered what makes a face memorable, a recent study has just found the answer. It's all to do with distinctive features - the kind that make a person stand out.
Holger Wiese, a psychologist at the Friedrich Schiller University Jena in Germany, has been investigating why we remember some faces better than others. And before you question why on earth there's a picture of Angelina Jolie to explain his theory, stick with us.
So, someone like Angelina Jolie, who has the most recognisable pout in Hollywood, is more memorable because of this.
However, Weise's study also found that less attractive people with distinctive features were the easiest to recall.
"Until now, we assumed that it was generally easier to memorise faces which are being perceived as attractive - just because we prefer looking at beautiful faces", Weise said.
However, after he conducted a test using photographs of faces with strong facial features, Weise proved this wrong.
So - anyone who's hang ups about their nose, listen up. It could make you harder to forget.
