Big thanks to Rick Davies (http://mande.co.uk) for pointing us to this 50 minute presentation by Dan Kahan (Yale Law School) on cultural cognition and how it effects peoples perceptions of evidence. It is part of a wider body of work by The Cultural Cogition Project, also at the Yale Law School.
There is also an associated paper, available as pdf: “Cultural Cognition of Scientific Consensus” by Dan M. Kahan, Hank Jenkins-Smith, Donald Braman, Journal of Risk Research, Vol. 14, pp. 147-74, 2011, Yale Law School, Public Law Working Paper No. 205
