Abstract
Many western democracies experienced significant resistance to public health measures designed to curb the spread of the COVID-19 virus. Although there were complex reasons for this resistance, right-wing populist forces seem to have played a significant role in fueling it. Studies show a strong correlation between right-wing populist support and resistance to COVID-19-mitigating measures including vaccination, and those who supported these populist movements were more likely to suffer and die from the virus. The question thus arises: why do people support these movements which openly undermine their own health interests? This paper addresses this question from a social-psychological perspective. Specifically, it draws on social identity theory to explain the considerable success of right-wing populism's radical anti-health agenda and to offer some suggestions about how this negative influence may be countered.
