"The COVID-19 pandemic has uncovered prejudices, systemic inequities and critical feelings about governmental institutions around the globe. Since the start of the pandemic, the 12 nations that make up South America have had more than 67 million cases and 1.3 million fatalities. Public trust in and ... willingness to speak out about government responses to COVID-19 in each nation have differed vastly. Using spiral of silence, this study (n =1248) explored support for governmental COVID-19 response and willingness to speak out about that response in four South American nations: Argentina, Brazil, Chile and Peru. Results revealed Chileans are more likely to speak out on government response to COVID-19 than other South American participants. In addition, climate of opinion and support for government response positively predict willingness to speak. These results further our international and cross-cultural understanding of spiral of silence." (Abstract) more
