Students in my Intro to Mass Media class have been asking similar questions (especially after viewing Stuart Hall's Race: The Floating Signifier) as these two esteemed academics on the Association of Internet Researchers' listserv:
Charles: My applied ethics class, we're reading an essay by Robinson A. Grover, "the New State of Nature and the New Terrorism," which argues that new media and globalization have brought about a new version of Hobbes' war of each against all, etc.
Radhika: hmmm
Charles: I attempted to buttress some of Grover's claims with the work of Cass Sunstein, his notion of "The Daily Me," etc.
This inspired one of my students to ask: are there studies, etc., that suggest that the new media, by giving us greater communication with "the Other" works to make us _less_ fearful of the Other, and thus, under some circumstances at least, _more_ likely to engage in aggressive behaviors, including warfare?
