What motivates people to defend science: Evidence from the 2017 March for science

Abstract

The 2017 March for Science was an international march organized in response to concerns over the Trump administration’s misuse of science that drew unprecedented numbers of supporters as well as attention from the media, celebrities, and political figures. The March’s turnout and publicity begs the question: what motivates people to defend science? Using data from a survey of March for Science listserv members in the US, we used a structural equation model to test posited relationships between self- and collective response efficacy, perceived threat, anger, fear, and the intention to engage in advocacy to defend science. We found that each of these constructs were associated with the intention to engage in advocacy, illuminating the motivators that lead to this intention and how individuals may be activated to engage on behalf of science in the future. These insights have both theoretical and practical significance, as advocacy is integral for both supporting and advancing fact-based policy- and decision-making.
