Are geeks guilty of groupthink? A network expert argues that less social networking would produce more radical innovation on the Internet. “An overabundance of connections over which information can travel too cheaply can reduce diversity, foster groupthink, and keep radical ideas from taking hold,” Viktor Mayer-Schönberger, director of the Information + Innovation Policy Research Center at the National University of Singapore, writes in this week's issue of the journal Science. That may be one of the reasons why much of the open-source software currently being produced is rarely altered in anything more than an incremental manner, Mayer-Schönberger says. “The basic point that I'm trying to make is … how do we get to the next stage of the Internet, the new-generation Internet, the radical innovation, rather than another dot release on the Firefox browser?” he told me today.
