This Report summarizes the preliminary conclusions of Study No. 1 in the Cultural Cognition Project’s “Evidence-based Science Filmmaking Initiative.” Conducted in collaboration with the Annenberg Public Policy Center at the University of Pennsylvania, the goal of the initiative is to promote the integration of the emerging science of science communication into the craft of science filmmaking. A principal aim of the first study was to develop a valid and reliable science curiosity scale. The report describes the development of the scale, its psychometric properties, and its success in predicting engagement with a science documentary on evolution produced by Initiative collaborator Tangled Bank Studios. The report also presents evidence on variation in science curiosity, and engagement with the documentary conditional on science curiosity, among culturally diverse groups, including ones holding opposing beliefs on human evolution. Provisional conclusions, and plans for follow up research, are discussed.
