I‘m putting on a conservative, understated hat. This could be the worst paper I have seen — an ad hom argument taken to its absurd extreme, rebadged as “science”.
Professorial fellow Stephan Lewandowsky thinks that skeptics who are “greatly involved” in the climate debate believe any kind of conspiracy theory, including that the moon landings never happened, that AIDS is not due to HIV, and that smoking doesn’t cause cancer. But he didn’t find this out by asking skeptics who are “greatly involved” in the climate debate or by reading their popular sites. He “discovered” this by asking 1,000 visitors to climate blogs. Which blogs? He expertly hunted down skeptics, wait for it… here:
- Scot Mandia,
- A Few Things Ill Considered,
- Hot-Topic (NZ)
- Trunity (unconfirmed?)
- John Cook (unconfirmed?)
This is the point where the question has to be asked: Did Lewandowsky, Oberauer, and Gignac really think they would get away with it? Did none of the reviewers at “Psychological Science“ think to ask if the “sampling” would affect the results?
