How influential deniers flock to their echo chamber (and stay there)

A new paper in Nature Climate Change discusses from where the elite in the USA get their opinions about climate. Echo chambers are significant. The elite are described in the abstract as "the community of political elites engaged in the contentious issue of climate politics in the United States". The researchers used exponential random graph (ERG) modelling (don't ask me :D) and found that both "the homogeneity of information (the echo) and multi-path information transmission (the chamber) play significant roles in policy communication".

There's a press release at the National Socio-Environmental Synthesis Center (SESYNC) of the University of Maryland (where the lead author, Lorien Jasny, resides). It translates the social science speak into everyday language.
