Brazilian Presidential Pronouncements in the Pandemic: Effectiveness in Crisis Communication and Rule Properties.

This work analyzed the six official statements of the president of Brazil that were broadcast on radio and television during the first 4 months of COVID-19 contamination in the country, regarding the efficacy in communicating the crisis and dimensions of rules. We observed a higher frequency of ineffective excerpts in the statements, especially in the categories "effective fear incitement" and "respect." The categories "speed" and "expression of empathy" showed high efficacy. Additionally, there was a higher recurrence of implicit and inaccurate rules and rules opposing the recommendations of experts. These results indicate that the analyzed statements were ineffective in crisis communication and control of behaviors combating the pandemic in Brazil. The analysis of governmental practices by behavioral science can be useful in the planning of public policies.
