Deirdre Macken has a great piece on today’s Fin, riffing off Cardinal “I spend a lot of time studying this stuff” Pell to the general issue of the challenge to expertise in both productive (Wikipedia) and unproductive (climate science rejectionism) forms. Paywalled unfortunately, but here’s the link for anyone who can use it.
Macken, correctly I think, points to postmodernism as a contributor to the process. I’ve discussed this before (do a search) and I know it’s more complicated than that, but the vulgarised version of postmodernism as denying any special status to scientific knowledge as compared to other “knowledges” has certainly been embraced on the political right in a way that few of its original proponents could have anticipated.
