What your cell phone knows about you
Researchers are using cell phones to get a "god's eye" view of people, to predict everything from changes in the stock market or to when you are getting sick.
The information recorded in cell phones are helping researchers understand how people respond to getting sick, how people make decisions about health and even how ideas spread throughout communities. Alex Pentland of MIT's Human Dynamics Laboratory and the MIT Media Lab, talks with Here and Now about the information that can be gleaned from cell phones.
