Guided by neo-institutional theory, this study compares how researchers from science, technology, engineering, and math disciplines differ from researchers from the arts, humanities, and social sciences fields in terms of how macro- and meso-level concerns shaped their willingness to conduct public engagement. Focus group discussions conducted among researchers based in Singapore revealed that science, technology, engineering, and math and arts, humanities, and social sciences researchers held different macro-level concerns. Particularly, science, technology, engineering, and math researchers raised more concerns about media misrepresentation, while arts, humanities, and social sciences researchers were more concerned about receiving political repercussions and public backlash. With regard to meso-level considerations, researchers from all disciplines cited similar institutional constraints for public engagement; however they possessed varying public engagement competencies and held differing perceptions of their social duty to engage the public. Hence, researchers of different disciplines desired different kinds of media training. Policy and managerial implications as well as directions for future research were provided.

Informed by the notion of spillover effects between two phenomena, this study examines how differences in prior attitudes would influence the relationships posited by the influence of presumed media influence (IPMI) model. Specifically, this study examines how pre-existing favorable and unfavorable attitudes toward genetically modified (GM) food are associated with audiences’ intention to consume nano-enabled food. The results of a nationally representative survey with 1,000 respondents found general support for the IPMI from media attention to behavioral intentions, through attitude and social norms. Further, a multigroup analysis of the IPMI provided evidence for differences in the IPMI effects between the audiences with favorable and unfavorable pre-existing attitudes toward GM food. These results contribute to a stronger theoretical understanding of the IPMI in terms of how pre-existing attitudes toward a preceding food technology can have a spillover effect on how audiences make decisions regarding a newer food technology.

Fake science news is a type of fake news that can threaten the credibility of the scientific community. Scientists’ attention to fake science news can indirectly influence the way they react to tackling fake science news through socio-psychological factors. Applying the influence of presumed media influence (IPMI), this study examines how scientists’ attention to fake science news indirectly influences their support for initiatives to tackle fake science news through presumed harm of fake science news on other scientists and the general public, as well as their attitude and personal norm towards tackling fake science news. Specifically, this study explicates the behavioural outcome into support for education and support for legislation against fake science news. The results from a survey of 706 Singapore-based scientists supported the relationships posited in the IPMI. Theoretical and practical implications are discussed.

Scientists play important roles in conducting public engagement, but evidence shows that scientists perceive great challenges in doing so. Drawing broadly from the theory of planned behavior (TPB), this study examines factors predicting scientists’ willingness to conduct public engagement. This study further examines how perceived behavioral control (PBC) of conducting public engagement would moderate the relationships between the proposed predictors and scientists’ willingness to conduct public engagement. Using survey data collected from 706 scientists based in Singapore, this study found that attitude toward and personal norms of conducting public engagement, as well as PBC, significantly predicted scientists’ willingness to conduct public engagement. Notably, PBC interacted with attitude toward conducting public engagement, the perceived descriptive norms, the perceived positive media influence, and the perceived negative external norms of conducting public engagement, as well as personal norms of conducting public engagement to predict scientists’ willingness to conduct public engagement. We postulated the key role that the perception of the ease or difficulty plays in motivating scientists to conduct the skill-intensive endeavor explains the significant moderating effects. The theoretical implications on the TPB and the practical implications for public engagement are further discussed.
