Ideological symmetry in outgroup bias: a neuroimaging study in the context of vaccine hesitancy

One of the most contentious debates in political psychology relates to the existence of ideological (a)symmetry in outgroup bias. Recent neuroimaging and psychological studies circumvented previous critics on the inclusion of ideologically biased outgroups by targeting the ideological outgroups themselves (rightists for leftists, and leftists for rightists); their findings confirmed the asymmetry claim – this was particularly robust and informative at the neural level. Nevertheless, the recent pandemic provided a new opportunity for the investigation of ideological (a)symmetry in outgroup bias by introducing an ideologically-neutral, yet highly discriminated and stigmatized group – vaccine hesitant individuals. In this pre-registered study, 50 Finnish adults were scanned in magnetoencephalography to delineate function-specific neural mechanisms of bias against vaccine hesitancy. The results show a clear neural bias against vaccine hesitancy regardless of political inclination. The findings reported here contribute to the present debate by selecting a unique ideologically neutral target and revealing that ideological (a)symmetries in outgroup bias are highly context dependent.
