How institutional factors at US land-grant universities impact scientists' public scholarship

The call for public scholarship to emphasize the broader impacts of science has raised questions about how universities can support this work among their scientists. This study quantitatively assesses how institutional factors shape scientists' participation in public scholarship, a subset of public engagement focusing on scientists' involvement in public debate and democratic decision-making related to science policy. Based on a 2018 survey of scientists from 46 US land-grant universities (N = 6,242), hierarchical linear modeling results show that institutional factors, including tenure guidelines and the extent of government funding, play a minor role in influencing scientists' public scholarship participation. More importantly, scientists' perceptions of the university climate on support for engagement, including support from high-level administrators and for graduate students, are significant predictors of participation in public scholarship. Ultimately, these findings support the recommendation that universities should coordinate individual motivations with institutional missions to support a broader culture of public engagement.
