There’s a lively discussion of “cyberbalkanization” on the Deliberative Democracy Consortium’s blog. The discussion was prompted by a New York Times article last Sunday that claimed that people use the Internet to sort themselves into small, homogeneous groups and to filter out views that don’t interest or please them. I’ve pasted my comment below, but I recommend the full discussion:

For my money, the best theoretical account of cyberbalkanization is still a 1996 paper by Marshall van Alstyne and Erik Brynjolfsson. They predict that the Internet will help people who are so inclined to increase the range and diversity of their information and contacts. They also predict that the Internet will allow people to “filter” out unwelcome ideas or contacts and to form narrow, exclusive groups. So the technology will not determine the outcome; people’s motives will. And clearly, people have various motives. Some prefer diverse ideas and serendipitous encounters; others want to shun people who are different and simply confirm their own prejudices.

I am fairly pessimistic about the cyberbalkanization problem, not because of the technology, but because of cultural trends in the US. Niche marketing has become highly sophisticated and has divided us into small groups. There’s more money to be made through niche programs than by creating diverse forums for discussion. Meanwhile, people have developed consumerist attitudes towards news, looking for “news products” that are tailored to their private needs. And broad-based organizations have mostly shrunk since the 1950s. In this context, the Internet looks like a means to more balkanization. In a different context, such as contemporary Saudi Arabia, it may have a much more positive impact.
