Boomerang effects in science communication: How motivated reasoning and identity cues amplify opinion polarization about climate mitigation policies

Motivated reasoning in response to disconfirming science information presents a challenging barrier to science communication. This article presents a novel approach to emphasis framing, in which functionally equivalent information is framed using ideologically consistent values and tailored to the audiences. In contrast to traditional framing approaches, science information is held constant across frames and only interpretations of the information are varied. Results from an experiment provide initial support for this ideology-based framing approach. Persuasive effects are stronger for an ideologically congruent frame than for an incongruent frame, and no boomerang effects were observed. We discuss implications and directions for future research.

Significance During last month’s UN General Assembly, President Jair Bolsonaro unsuccessfully argued that his government was controlling deforestation in the Amazon region. Reports indicate that between August 2020 and July 2021, nearly 8,800 square kilometres (km2) of forest were cut down. Impacts Despite stronger international pressure, the outlook for forest preservation is alarming absent a well-structured policy for Amazonia. Major Brazilian business sectors will face significant risks from international climate pushback without policy improvements. Brazil will argue for greater international assistance to offset the costs of climate mitigation policies.

Mitigation Policies

AbstractThe Paris agreement identifies the importance of the conservation, or better, increase of the land carbon sink. In this respect, the mitigation policies of many forest rich countries rely heavily on products from forests as well as on the land sink. Here we demonstrate that Sweden’s land sink, which is critical in order to achieve zero net emissions by 2045 and negative emissions thereafter, is reduced to less than half when accounting for emissions from wetlands, lakes and running waters. This should have implications for the development of Sweden’s mitigation policy. National as well as the emerging global inventory of sources and sinks need to consider the entire territory to allow accurate guidance of future mitigation of climate change.
