I don't know if others have seen this, but I found it an interesting 
application of network ideas.  It also gives one pause regarding all of 
our work in social science.  Basically, the author traced a recent 
scientific "belief" proposed in medical research that is probably untrue 
but lived and became believed to be true through a pattern of citations, 
even though the preponderance of evidence did not support that belief.

The authors draw mostly on Kleinberg's and Newman's network work. Can we 
improve on this analysis, say, with some good old fashioned 
Friedkin-Johnsen social influence modeling?
