The power of citizen science to contribute to both science and society is gaining increased recognition, particularly in physics and biology. Although there is a long history of public engagement in agriculture and food science, the term ‘citizen science’ has rarely been applied to these efforts. Similarly, in the emerging field of citizen science, most new citizen science projects do not focus on food or agriculture. Here, we convened thought leaders from a broad range of fields related to citizen science, agriculture, and food science to highlight key opportunities for bridging these overlapping yet disconnected communities/fields and identify ways to leverage their respective strengths. Specifically, we show that (i) citizen science projects are addressing many grand challenges facing our food systems, as outlined by the United States National Institute of Food and Agriculture, as well as broader Sustainable Development Goals set by the United Nations Development Programme, (ii) there exist emerging opportunities and unique challenges for citizen science in agriculture/food research, and (iii) the greatest opportunities for the development of citizen science projects in agriculture and food science will be gained by using the existing infrastructure and tools of Extension programmes and through the engagement of urban communities. Further, we argue there is no better time to foster greater collaboration between these fields given the trend of shrinking Extension programmes, the increasing need to apply innovative solutions to address rising demands on agricultural systems, and the exponential growth of the field of citizen science.
Climate scientists need the trust of lay audiences if they are to share their knowledge. But significant audience segments—those doubtful or dismissive of climate change—distrust climate scientists. In response, climate scientists can undertake one of two general communication strategies for enhancing trust, each appealing to one of two broad types of cognitive processing mechanisms. In the first, the communicator displays traits like humor, attractiveness, vigorous delivery, and likeability that audiences use as heuristics in determining whom to trust. But this strategy is unlikely to be successful with the very audiences who are its main targets, since those audiences will be primed to employ a more analytic and critical approach to assessing trustworthiness. In the second communicative strategy, the communicator earns trust by undertaking burdens and commitments and making herself vulnerable in ways her audience can enforce. This vulnerability signals her trustworthiness, since the audience can reason that she would not undertake such risks unless she was confident in what she was saying. Climate scientists have a variety of ways of making themselves vulnerable, including committing themselves to engaging with doubtful and dismissive audiences, undertaking burdens of proof to argue with them, empowering audiences to assess the science themselves, admitting error, and focusing on small issues. Overall, when adopting the second strategy, climate scientists must extend trust in order to earn trust, committing themselves to an on‐going relationship within which their true trustworthiness will become apparent.

Hearing acuity and the relationships between untreated hearing deficits and emotional state, cognitive functioning, and social integration were examined in 239 physically healthy, independent-living elderly men and women with a mean age of 72 years. Air-conduction, pure-tone thresholds in both ears were determined at high- and mid-frequencies, and participants were also given the Speech Perception in Noise test. Multivariate techniques were used to test for associations between hearing acuity and scores from the Kellner-Sheffield Symptom Questionnaire, the Jacobs Cognitive Screening Exam, the Halstead Category Test, the Wechsler Memory Scale, and the Interview Schedule for Social Interaction. No deleterious effects of untreated hearing deficits on emotional status or social integration were found. The findings suggest that those with a hearing loss perform less well on verbal but not on nonverbal tests of cognition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
