Today I continue my exploration of the dubious scholarship in the contrarian touchstone known as the Wegman report, this time focusing on the report’s background section on social network analysis. As many readers may recall, Wegman et al used a simplistic analysis of co-author relationships to speculate about supposed lack of independence between researchers in paleoclimatology, accompanied by lapses of rigour in the peer review process. This, of course, echoed similar accusations by self-styled climate auditor Steve McIntyre.
In both the original Wegman report and a subsequent follow-up paper by Yasmin Said, Wegman and two others, the background sections on social network research show clear and compelling instances of apparent plagiarism. The three main sources, used almost verbatim and without attribution, have now been identified. These include a Wikipedia article and a classic sociology text book by Wasserman and Faust. But the papers rely even more on the third source, a hands-on text book that explores social network concepts via the Pajek analysis software package – the same tool used by the Wegman team to analyze “hockey stick” author Michael Mann’s co-author network.
Not only that, but the later Said et al paper acknowledges support from the National Institutes on Alcohol Abuse and Alcoholism, as well as the Army Research Laboratory, raising a host of new issues and questions. And chief among those questions is this: Will George Mason University now finally do the right thing and launch a complete investigation of the actions and scholarship of Wegman and Said?
