More than 60 years ago, in his "Foundation" series, the science fiction novelist Isaac Asimov invented a new science psychohistory " that combined mathematics and psychology to predict the future. Now social scientists are trying to mine the vast resources of the Internet " Web searches and Twitter messages, Facebook and blog posts, the digital location trails generated by billions of cellphones " to do the same thing. The government is showing interest in the idea. This summer a little-known intelligence agency began seeking ideas from academic social scientists and corporations for ways to automatically scan the Internet in 21 Latin American countries for "big data," according to a research proposal. The three-year experiment ... is being financed by the Intelligence Advanced Research Projects Activity, or Iarpa. The automated data collection system is to focus on patterns of communication, consumption and movement of populations. It will use publicly accessible data, including Web search queries, blog entries, Internet traffic flow, financial market indicators, traffic webcams and changes in Wikipedia entries. It is intended to be an entirely automated system, a "data eye in the sky" without human intervention. Some social scientists and advocates of privacy rights are deeply skeptical of the project, saying it evokes queasy memories of Total Information Awareness, a post-9/11 Pentagon program that proposed hunting for potential attackers by identifying patterns in vast collections of public and private data.
