We assessed differences between Australians’ perceptions of their own compliance with coronavirus restrictions and their perceptions of community compliance.We surveyed a national quota sample of 1,690 Australians in August and September 2020. We asked pParticipants about reported their level of compliance with coronavirus restrictions in their state/territory. We then asked them toand estimated the compliance from others in their state/territory.: Overwhelmingly, most people reported complying with restrictions. They believed their fellow community members were much less compliant. Age and other demographics were only weakly associated with self-reported compliance and perceptions of others’ compliance.The results are consistent with prevalent cognitive biases, including the tendency to believe one is better-than-average, and to more easily recall instances of deviances from social norms.We recommend public health messaging avoids amplifying instances of social transgressions of coronavirus restrictions. Instead, the widespread nature of social compliance with restrictions across the country should be emphasised.
