Wegman, who was chair of the National Academy of Sciences' (NAS) Committee on Applied and Theoretical Statistics, was tapped in '06 by Republican representatives Joe Barton and Ed Whitfield to assemble a so-called "expert panel" to critique the famous hockey stick, a graph illustrating a thousand-year temperature record as reconstructed by climate scientists Michael Mann, Raymond Bradley and Malcolm Hughes. But Silicon Valley entrepreneur John Mashey has since demonstrated that, rather than convene a group of experts, Wegman tapped a couple of grad students and together they produced a report that was generously plagiarized from Bradley's own work and then twisted -- or just misrepresented -- to appear to undermine the hockey stick and its creators.
