The gradual decline of colonial ideologies (2009–2018): A latent growth curve analysis of historical negation and symbolic exclusion among settler colonizers

Political Psychology, Volume 47, Issue 2, April 2026.
Abstract In nations laden with colonial inequities, settler colonizers protect their structural advantages through ideologies that (a) distance the injustices of colonization from contemporary society (historical negation) and (b) exclude Indigenous culture from the mainstream national identity (symbolic exclusion).
