Facebook likes can indicate sexuality. The things you like on Facebook can paint a fairly accurate picture of who you are, according to a University of Cambridge researcher who created the Facebook app myPersonality. Some of these are obvious ("most fans of the satirical, Fox News–mocking show 'The Colbert Report,' are Democrats"); some, however, are not. A program written to mine the data collected by myPersonality on 58,000 users "correctly identified gay men 88 percent of the time, even though less than 5 percent of them had liked things explicitly related to sexual orientation." The findings, though clearly valuable to marketers, pose a striking existential question: are we nothing more than a list of likes and dislikes? [Science News]
