The rise of social media platforms has reshaped our communication landscape, fostering diverse content creation and impacting the dynamics of information dissemination. Within this ecology, scientists have emerged as increasingly pivotal risk communicators on social media: for example, scientists were propelled to the forefront of public discourse during the Covid-19 pandemic, positioning themselves as experts in these online information environments. This project explores how scientists may leverage social media to present their research and themselves to the public, as well as how public audiences might respond to this “self-presentation.” Specifically, how might certain self-presentation strategies impact audience perceptions of scientists' competence, warmth, humility, and transparency, and how might these perceptions relate to risk understanding and support for risk-related policies? Understanding the potential persuasive impacts of scientists’ social media use may support the identification and development of effective risk communication practices not only for scientists, but other stakeholders on social media and beyond. This research aims to help empower scientists at all levels and from different backgrounds and experiences in risk communication.This research addresses these guiding questions by examining the impact of scientists' self-presentation strategies across two relevant areas: (1) the dissemination of their research outcomes and (2) the contextualization of their research processes. The researchers explore how these strategies may impact audiences’ perceptions of scientists as risk communicators through two mechanisms—expectancy violation and identification—and how source perceptions may relate to risk perceptions and policy support. Lastly, the researchers examine two message-level features of these self-presentation strategies (personalization and emotionalization) as potential moderators that may impact these relationships. To test the conceptual framework, the researchers are collecting and analyzing data from two randomized experiments that involve a general population sample of adults. Altogether, this research bridges literature on social media with strategic risk communication and persuasion to offer a more nuanced perspective of an evolving aspect of risk communication as situated in a networked environment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

社交媒体平台的兴起重塑了我们的传播格局，促进了多样化的内容创作并影响了信息传播的动态，在这个生态中，科学家已成为社交媒体上日益关键的风险传播者：例如，科学家被推到了最前沿。该项目探讨了科学家如何利用社交媒体向公众展示他们的研究和自己，以及公众对此有何反应。 “自我展示”。具体来说，某些自我展示策略如何影响观众对科学家的能力、热情、谦逊和透明度的看法，以及这些看法如何与风险理解和对风险相关政策的支持联系起来？科学家使用社交媒体的说服力影响不仅可以支持科学家，也可以支持社交媒体及其他领域的其他利益相关者识别和开发有效的风险沟通实践。这项研究旨在帮助赋予各级、不同背景和经验的科学家权力。风险沟通。本研究通过检查来解决这些指导性问题科学家自我展示策略在两个相关领域的影响：(1) 研究成果的传播和 (2) 研究过程的情境化 研究人员探讨了这些策略如何影响受众对科学家作为风险传播者的看法。最后，研究人员研究了这些自我呈现策略的两个信息层面特征（个性化和情感化），作为可能影响这些策略的潜在调节因素。来测试关系。在概念框架下，研究人员正在收集和分析来自两项随机实验的数据，这些实验涉及成年人的一般人群样本。总的来说，这项研究将社交媒体文献与战略风险沟通和说服联系起来，为不断变化的方面提供更细致的视角。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
