Clive Thompson on Real-World Social Networks vs. Facebook 'Friends'
Waber, a PhD student in MIT's Human Dynamics Group, studies the way groups interact socially — based on who's talking to whom. But unlike most social scientists, who simply ask people about their behavior, Waber and his colleagues measure it. They outfit employees with special badges that work with base stations to log all conversations between employees, including location and duration. With this data, Waber's team can plot exactly how information flows inside a firm.
This type of research has evolved into a new field called reality mining. By tracking people using location-aware devices like mobile phones or electronic badges, scientists are revolutionizing our understanding of how social networks function.
