The language of crisis: spatiotemporal effects of COVID-19 pandemic dynamics on health crisis communications by political leaders

In times of crisis, communication by leaders is essential for mobilizing an effective public response. During the COVID-19 pandemic, compliance with public health guidelines has been critical for the prevention of infections and deaths. We assembled a corpus of over 1500 pandemic-related speeches, containing over 4 million words, delivered by all 50 US state governors during the initial months of the COVID-19 pandemic. We analyzed the semantic, grammatical and linguistic-complexity properties of these speeches, and examined their relationships to COVID-19 case rates over space and time. We found that as COVID-19 cases rose, governors used stricter language to issue guidance, employed greater negation to defend their actions and highlight prevailing uncertainty, and used more extreme descriptive adjectives. As cases surged to their highest levels, governors used shorter words with fewer syllables. Investigating and understanding such characteristic responses to stress is important for improving effective public communication during major health crises.

Engagement Analysis of Canadian Public Health and News Media Facebook Posts and Sentiment Analysis of Corresponding Comments during COVID-19

During the COVID-19 pandemic, key stakeholders have used social media to rapidly disseminate essential information to the public to help them make informed health-related decisions. Our research examined how the public responded to official actors’ Facebook posts during COVID-19 and examined the comment sentiment and post engagement rates. CBC News and CTV News received a greater proportion of negative comments and a lower average post engagement rate compared with Healthy Canadians. Additionally, the proportion of negative and positive comments varied over time for all sources; however, over 30% of the comments for all three actors were consistently negative. Key stakeholders should monitor the public’s response to their social media posts and adapt their messages to increase the effectiveness of their crisis communication efforts to encourage the adoption of protective measures.

The Matching Effect of Destinations’ Crisis Communication

The match between destinations’ crisis communication sources and crisis types, and their impacts on tourists’ travel intentions, has not yet been investigated. This research explored the effect of destinations’ crisis communication on tourists’ travel intentions based on different crisis types (i.e., victimized and preventable crises) and communication sources (i.e., from the government, businesses, and other tourists). Results showed that crisis type had a matching effect on the impact process of crisis communication sources on tourists’ travel intentions. In addition, the mediation effects of tourists’ heuristic processing and perceived safety on destinations’ crisis communication–tourists’ travel intentions were confirmed. This study uncovered a matching effect of destinations’ crisis communication sources and crisis types. Results offer valuable theoretical and practical implications regarding destinations’ crisis communication agendas, crisis communication systems, and strategies for alleviating negative consequences of crises.

Improving Crisis Communication Efficiency Through Nudging

Human action is not rational, and this irrationality manifests itself especially in decisions under uncertainty – the COVID-19 pandemic is one example of many in this respect. At the same time, various branches of research have been able to identify systematic patterns in irrational human behavior, and these have been attempted to be subsumed under the umbrella term of 'nudging'. Nudging describes the intentional change of decision architectures with the purpose of transforming irrationalities and/or distortions of human perception into predictable action. Thus, nudging represents a potent communication tool, especially in crisis communication scenarios. After presenting the basic theoretical assumptions of nudging, two examples of highly effective crisis communication strategies employed during the COVID-19 pandemic will be used to illustrate, contextualize, and reflect on central mechanisms and workings of nudging. This chapter ends with a summary of the most central findings as well as a critical reflection on potential future fields of action.
