Abstract
Trust in science post-Covid appears to be a complex matter. On the one hand, the COVID-19 pandemic added value to the epistemic trustworthiness of scientific opinion and its potential to drive evidence-based policies, while it also spurred scientific distrust and societal polarization (e.g., vaccines), especially on social media. In this work we sought to understand the ways in which trust in science might be bolstered by adopting a multistakeholder perspective. This objective was achieved by considering stakeholders’ views on (a) _how_ perceived key actors affect trust in science, and (b) _what_ proposed actions can be taken by each actor identified. Data were collected using 16 focus groups and 10 individual interviews across different European contexts with general public (_n_ = 66), journalists (_n_ = 23) and scientists (_n_ = 35), and were analysed using thematic analysis. Regarding _how_ perceived key actors affect trust in science, participants viewed policymakers, media, scientific and social media actors as occupying a dual function (facilitators and hinderers of trust in science), and pointed to the value of multi-actor collaboration. Regarding _what_ actions should be taken for enhancing trust in science, participants indicated the value of enhancing understanding of scientific integrity and practices, through science literacy and science communication, and also pointed to social media platform regulation. Implications stemming from the data are discussed, considering how multiple identified stewards of trust can contribute to an ecosystem of trust.
