In a new study conducted by Stanford University in California and the University of Cambridge through an app on Facebook called ‘myPersonality’, there were 86,220 volunteers who completed a 100-item personality questionnaire. They also gave the researchers access to their ‘likes’. The scores revealed five traits: openness, conscientiousness, extroversion, agreeableness, and neuroticism.
The app also allowed the users to ask friends and family to answer a 10-item test about the test subject.
What this showed was that the computer could predict the user’s personality better than any co-worker based on 10 Facebook likes and even better than a close friend or roommate with 70 like; a parent or sibling with 150 likes; a spouse with 300 likes.
They found the average Facebook user has 277 liked pages.
