” Researchers from The University of Western Australia
have examined what motivates people who are greatly
involved in the climate debate to reject scientific
The study Motivated Rejection of Science, to be
published in Psychological Science, was designed to
investigate what motivates the rejection of science in
visitors to climate blogs who choose to participate in
the ongoing public debate about climate change.
More than 1000 visitors to blogs dedicated to
discussions of climate science completed a questionnaire
that queried people’s belief in a number of scientific
questions and conspiracy theories, including: Princess
Diana’s death was not an accident; the Apollo moon
landings never happened; HIV causes AIDS; and smoking
causes lung cancer. The study also considered the
interplay of these responses with the acceptance of
climate science, free market ideology and the belief
that previous environmental problems have been resolved.
The results showed that those who subscribed to one or
more conspiracy theories or who strongly supported a
free market economy were more likely to reject the
findings from climate science as well as other sciences.
The researchers, led by UWA School of Psychology
Professor Stephan Lewandowsky, found that free-market
ideology was an overwhelmingly strong determinant of the
rejection of climate science. It also predicted the
rejection of the link between tobacco and lung cancer
and between HIV and AIDS. Conspiratorial thinking was a
lesser but still significant determinant of the
rejection of all scientific propositions examined, from
climate to lung cancer.
“Blogs have a huge impact on society and so it’s
important that we understand the motivations and the
reasoning of those who visit blogs to contribute to the
discussion. There has been much research pointing to
the role of free-market ideology in rejecting climate
science, but this is the first time it’s been shown that
other scientific facts, such as the link between HIV and
AIDS, are also subject to ideological rejection,”
Professor Lewandowsky said.
By contrast, a major determinant of the acceptance of
science was the perceived consensus among scientists.
The more agreement among scientists, the more people
were likely to accept the scientific findings.
“It is important to understand the role of perceived
consensus because it highlights how damaging the media’s
handling of climate issues can be when they create the
appearance of a scientific debate where there is none:
More than 90 in 100 climate researchers agree on the
basic fact that the globe is warming due to human
greenhouse gas emissions,” Professor Lewandowsky said.”
