Research suggests that conservatives and liberals respond to science
information messages differently when the issue is politically-polarised.
When presented with information about scientific consensus regarding
climate change, denial may increase rather than decrease among
conservatives (a phenomenon termed the worldview backfire effect). However,
previous research has typically used consensus messages focusing on the
existence of anthropogenic climate change. This study investigated the
effects of expert consensus messages relating to the environmental and
economic impacts of climate change on the dependent variables of mitigation
and adaptation support, with trust in experts moderating these
relationships. We randomly allocated self-identified conservatives (*n*=276)
to one of three science information messages (economic impact,
environmental impact, and antibiotic overuse). Findings suggest that 1) The
worldview backfire effect may be overstated, and 2) shifting focus from the
environmental impacts of climate change to its dire economic effects may
increase conservatives’ willingness to support climate change mitigation
policies.
