An Australian study has outed climate change deniers as falling within one of two categories - radical free marketeers or nutjobs.
The paper, titled “NASA faked the moon landing – Therefore (Climate) Science is a Hoax: An Anatomy of the Motivated Rejection of Science”, was based on a survey of more than 1000 visitors to blogs dedicated to discussion of climate change.
“We find that endorsement of a laissez-faire conception of free-market economics predicts rejection of climate science,” the paper says. “We additionally show that endorsement of a cluster of conspiracy theories (e.g., that the CIA killed Martin Luther King or that NASA faked the moon landing) predicts rejection of climate science as well as the rejection of other scientific findings.”
The paper says that a staunch belief in free markets was an overwhelmingly strong factor in the rejection of climate science and was a stronger factor than conspiratorial thinking.
