The relationships of influence and activity between academics and other actors (public, private, and nongovernmental) in the policy process are complex.Although older work often argued academic research at best had an indirect "environmental" or "enlightenment" effect on policy-makers, (May et al. (2016). Policy, 36, 195) recently argued that in the US case previous studies misconstrued the role of academic policy advice because they surveyed "average" academics and in so doing missed the significant impact of a small elite group of "hyper-experts" within an already small group of "super-users" interacting on a constant basis with government policy-makers. This article draws upon data from a survey of academics in four fields (Business, Engineering, Health and Politics) in six major Canadian Universities to map out the relationships existing between academics and other actors in the public, private, and non-governmental sectors and test for the existence of this elite pattern of interaction in a second country.
