Psychologists at the University of Cambridge say they can now accurately predict details of our personalities based simply on what we say we like on Facebook.
After analysing nearly 60,000 researchers achieved more than 80% accuracy on working out areas of our lives including race, religion, sexuality and political leanings. They say the research could have a profound impact in areas such as advertising and market research.
Researcher Dr David Stillwell from Cambridge University said: "The average person on Facebook has more than 150 "Likes" so when you bring all of those pieces of information together you can see the average personality of a person."
