Computers can read individuals as well as their partner and better than their friends just by using their Facebook 'likes', a joint study from the University of Cambridge and Stanford University has found. The researchers came up with an algorithm that can scan a user’s likes to read their personality traits as accurately as a spouse. The algorithm could predict a user’s personality better than a work colleague with just 10 likes, better than a friend with 70, a family member at 150, and a spouse with 300 likes.
