Mapping public health responses with attitude networks: the emergence of opinion‐based groups in the UK’s early COVID‐19 response phase 2020-07-04 .txt text/plain 4273 249 51 However, in times of rapid societal change, novel opinion-based groups can emerge and provide a new basis for partisan identification and divergent collective behaviour. However, as previously seen during the Brexit debate in the United Kingdom, new 'opinion-based groups' (McGarty, Bliuc, Thomas, & Bongiorno, 2009) can emerge from social processes without clear relations to prior groups or socio-political structures. Using a novel network-based method, we explore whether opposing attitude-based clusters emerge over time and investigate whether factional attitude alignment becomes a basis for divergence in public health behaviour. In two complimentary studies, we investigate (i) the emergence of factional alignment in health attitudes during the early phase of the COVID-19 pandemic, (ii) consequences for maintaining public health behaviour, and (iii) the contribution of pre-existing social categories. These distinct attitudebased factions differed in behavioural compliance, suggesting that trust in science and health officials is a core basis for emerging COVID-19 opinion-based groups. ./cache/cord-271975-iygxrlxg.txt ./txt/cord-271975-iygxrlxg.txt
