PhD students Ricky Green and Mikey Biddlestone and Professor Karen Douglas asked participants from the UK and USA to imagine they had either recovered from Covid-19 or were currently infected. Participants asked to imagine that they had recovered were also presented with information regarding "immunity passports" and cautious versus incautious Covid-19 immunity information. Cautious information emphasised that past infection does not equal immunity whereas incautious information argued that past infection does equal immunity.

The research published by the Journal of Applied Social Psychology showed that for people asked to imagine past Covid-19 infection, reading about "immunity passports" was associated with lower social distancing and face covering intentions. Participants who then read incautious immunity information reported even lower intentions. However, when participants were presented with cautious immunity information these negative effects vanished. People asked to imagine that they were infected reported higher social distancing and hygiene intentions.
