Phone Use Indicates Social Network

Social network researchers gave subjects cell phones that recorded call information, text messages and how physically close callers were to their contacts. Researchers inferred which contacts were friends with 95% accuracy. Sometimes, patterns revealed a friendship in the making months before people considered each other friends. The data could also predict job satisfaction: people who spend all day on the phone with friends are generally unhappy with work.
