What do your Facebook Likes really say about you? According to a study, the pages, posts and public figures you Like on the social networking site can reveal surprisingly accurate information about your political and religious views, drug use, IQ and sexual orientation

The study, published by Cambridge University in the journal PNAS, analyzed the digital activity of more than 58,000 Facebook users

Participants volunteered their Likes, demographic profiles and psychometric testing results through an online application; the Likes were then fed into algorithms and verified with the information from profiles and personality tests
