Confirmation bias is absolutely universal. Freepers are just as prone to it as anybody else.
The whole point of the scientific method is to provide a method whereby confirmation bias can be bypassed and the truth be constantly approximated more closely.
Man’s capacity of doing tests on putative climate change causes is laughably inadequate.
Unless, of course, the "scientific method" has been buggered by bastardizing the peer review process, which is the case with "anthropogenic climate change".
It appears that authors of Yale studies aren't immune to it either:
If this public irrationality thesis were correct, the authors of the Yale study write, then skepticism about climate change could be traced to poor public comprehension about science and the solution would be more science education.If only those stupid skeptics would become better educated, they'd become believers.
Unfortunately, the current peer review process accomplishes almost exactly the opposite.
