Although group-related uncertainties have been shown to drive subgroups’ pursuit of autonomy, it is unclear whether all group-related uncertainties motivate subgroup autonomy. We hypothesized that social identity-uncertainty, not politico-economic uncertainty, about one’s subgroup is a key driver of support for subgroup autonomy. We measured Sardinian participants’ (N = 174) relative subgroup (Sardinian) and superordinate group (Italian) identity-centrality, identity-uncertainty, and politico-economic uncertainty to predict support for subgroup autonomy and superordinate group fragmentation. Results showed that subgroup identity-uncertainty, not politico-economic uncertainty, elicited stronger support for subgroup autonomy, especially among highly identified subgroup members. Superordinate group fragmentation was predicted by relatively weaker superordinate identity-centrality. Results suggest that subgroups’ pursuit of autonomy is driven by the hopes of reducing identity-uncertainty.
