Good reading on the kerfuffle of the day:
For the journalists involved, isn't there a danger of groupthink and group polarization that Cass Sunstein is worried about?
We can sharpen our understanding of this problem if we attend to the phenomenon of group polarization. The idea is that after deliberating with one another, people are likely to move toward a more extreme point in the direction to which they were previously inclined, as indicated by the median of their predeliberation judgments. With respect to the Internet, the implication is that groups of people, especially if they are like-minded, will end up thinking the same thing that they thought before-but in more extreme form.
