From Technologies of Politics and Control
Jump to navigation Jump to search

Mass collaboration and the aggregation of information enable potentially profound changes in business and politics. In this class, we will compare and contrast the transformations in economic life and collective decision-making processes brought on the information revolution. The discussions will also explore the role of open information systems on business and the scope for greater transparency and participation in government, politics and public life.

Class Discussion

Class Introduction by Amarquis 08:09, 21 February 2010 (UTC) Internet technologies allow for new kinds of information dissemination, collective action and decision making. Simply, is this a good thing or a bad thing? Does online communication lead to increased isolation, polarization of discussion and impoverished decision-making or does it harness a "wisdom of crowds," create improved ways of collecting information and allows groups to act on and make decisions about what they learn more effectively?

There is an old Freudian notion that crowds are irrationally exuberant, but for many factual tasks such as guessing the number of jelly beans in a jar, a group estimate is much more accurate than any individual estimate. However, in different circumstances, particularly those which require deliberation, different groups can come to very different decisions on the same issue. The research cited in the reading seems very poor in terms of measuring whether or groups converge or diverge and under what circumstances especially because they all have simple experimental problems including small sample sizes, a lack of even basic statistical analysis and they are not comparative. For example, if political blogs may not have many links to blogs with a different points of view (Though it's hard to know since Adamic and Glance don't compute the statistical significance of all but one of the differences they measure), do traditional news sources have a similar divergence? Given that markets do a better job of coordinating many kinds of activities what are the limits of prediction markets? It's clear that groupthink exists and that social forces bias decision-making, but is it possible to measure whether the Internet is making human decision making better? If so, what are some good experiments to run?
