How Can Educators Confront Science Denial?

Abstract

An unwillingness to consider empirical evidence that contradicts one’s desired conclusion, or science denial, is an enormous barrier to producing an informed citizenry. This essay explores literature on conceptual change and motivation to put forth fresh ideas on how curricula can foster science acceptance, or the willingness to engage in critical evaluation of evidence even when it holds potential to contradict one’s preferred conclusion. Drawing from motivated reasoning and self-determination theories, this essay builds a theoretical model of how negative emotions, thwarting of basic psychological needs, and the backfire effect interact to undermine critical evaluation of evidence, leading to science denial. The model guides the proposal of several design principles for creating instruction that is likely to foster science acceptance, and puts forth the evidence-laden narrative as an exemplar. This essay calls for instructional methods that facilitate motivation toward accuracy goals by fulfilling basic psychological needs as students engage in accuracy-oriented reasoning while evaluating evidence. The conclusion suggests further lines of research that might improve our understanding of science denial and how it can be confronted in the classroom.
