In a copy and paste at WUWT, Anthony Watts highlights a paper
with research suggesting why WUWT-ers are so willing to adopt their "climate hoax" conspiracy theories. The researchers, Tomas Ståhl
and Jan-Willem van Prooijen
argue that people holding irrational beliefs (such as Anthony Watts and his ragtag mob of climate hoax conspiracy theorists) lack analytical skills and/or don't value logic or evidence.
Even if one or two WUWT deniers were endowed with reasonably high cognitive skills, evidence suggests they wouldn't value these skills and therefore don't use them. When it comes to climate science, they discard those skills in favour of one of the myriad conspiracies Anthony touts.
In the abstract
of the paper itself, the authors write about how both analytical skills and motivation to be rational are required if one is to avoid adopting silly and unfounded beliefs:
We propose that part of the reason why unfounded beliefs are so widespread is because skepticism requires both sufficient analytic skills, and the motivation to form beliefs on rational grounds.
It's immediately obvious to anyone who reads the articles and comments at WUWT that the bulk of Anthony's commenters lack a lot more than the motivation to be rational. Most of them lack analytical skills. Oh, there are still a few WUWT fans who can string words together to form whole sentences, but they are few and far between.
