Motivated Rejection of Science

© 2016, © The Author(s) 2016. Some scientifically well-established results—such as the fact that emission of greenhouse gases produces global warming—are rejected by sizable proportions of the population in the United States and other countries. Rejection of scientific findings is mostly driven by motivated cognition: People tend to reject findings that threaten their core beliefs or worldview. At present, rejection of scientific findings by the U.S. public is more prevalent on the political right than the left. Yet the cognitive mechanisms driving rejection of science, such as the superficial processing of evidence toward the desired interpretation, are found regardless of political orientation. General education and scientific literacy do not mitigate rejection of science but, rather, increase the polarization of opinions along partisan lines. In contrast, specific knowledge about the mechanisms underlying a scientific result—such as human-made climate change—can increase the acceptance of that result.
