When Ideology Trumps Science: Why We Question the Experts on Everything from Climate Change to Vaccinations

This book reveals how embedded beliefs more so than a lack of scientific knowledge and understanding are creating a cognitive bias toward information that coincides with personal beliefs rather than scientific consensus-and that this anti-science bias exists among liberals as well as conservatives.

In 2010, an outbreak of whooping cough in California infected more than 8,000 people, resulting in the hospitalization of more than 800 people and the death of 10 infants. In 2015, an outbreak of the measles in Disneyland infected more than 125 people. Both the whooping cough and the measles are vaccine-preventable diseases (VPDs) that have been largely nonexistent in the United States for decades. As these cases demonstrate, individuals who prioritize ideology or personal beliefs above scientific consensus can impinge on society at large-and they illustrate how rejecting science has unfortunate results for public health and for the environment.

When Ideology Trumps Science examines how proponents of scientific findings and the scientists responsible for conducting and communicating the applicable research to decision makers are encountering direct challenges to scientific consensus. Using examples from high-stakes policy debates centered on hot-button controversies such as climate change, GMO foods, immunization, stem cell research, abstinence-only education, and birth control, authors Wolters and Steel document how the contested nature of contemporary perspectives on science leads to the possibility that policymakers will not take science into account when making decisions that affect the general population. In addition, the book identifies ways in which liberals and conservatives have both contested issues of science when consensus diverges from their ideological positions and values. It is a compelling must-read for public policy students and practitioners.
