***** To join INSNA, visit http://www.insna.org ***** Responding to Valdis' comment--Yes, SNA analysis of the climate change networks would be very interesting! I and co-PIs are currently designing a policy network research project to look at the diffusion of climate change ideas from the IPCC and other sources through various national policy making processes (Japan, Germany, US, Sweden, Net6herlands, Greece and perhaps others). Maybe we will find very different networks for "believers" and "contrarians" ideas about climate change. But at this point, I get the impression that virtually the entire scientific community outside a small circle in the US is filled with "believers." The IPCC, for instance, includes several hundred scientists who confer on this. This Human Dimensions conferences include thousands. They seem to review all evidence very carefully. **What, dear colleagues, do you think are the most important aspects of national climate change policy-making systems that influence whether believers or contrarians information dominates the debate and output? Please let us know. We want to test those various ideas in our comparative policy network project.

Here is an excerpt... Wall Street Journal; July 14, 2006; Page A12 > In addition to debunking the hockey stick, Mr. Wegman goes a step > further in his report, attempting to answer why Mr. Mann's mistakes > were not exposed by his fellow climatologists. Instead, it fell to two > outsiders, Messrs. McIntyre and McKitrick, to uncover the errors. > Mr. Wegman brings to bear a technique called social-network analysis > to examine the community of climate researchers. His conclusion is > that the coterie of most frequently published climatologists is so > insular and close-knit that no effective independent review of the > work of Mr. Mann is likely. "As analyzed in our social network," Mr. > Wegman writes, "there is a tightly knit group of individuals who > passionately believe in their thesis." He continues: "However, our > perception is that this group has a self-reinforcing feedback > mechanism and, moreover, the work has been sufficiently politicized > that they can hardly reassess their public positions without losing > credibility. > > In other words, climate research often more closely resembles a > mutual-admiration society than a competitive and open-minded search > for scientific knowledge. And Mr. Wegman's social-network graphs > suggest that Mr. Mann himself -- and his hockey stick -- is at the > center of that network. Since this has become a political issue, is the opposing group also an echo chamber? Similar to the red-blue political divide we see in the USA? Would be interesting to run Mark Newman's community algorithm on all scientists/papers involved in global warming, eh?
