This study examines the relationship between ideology and resistance to the government's apology to Asian victims of Japan's colonial rule policy, which varies according to political knowledge. Based on existing research, because only a limited percentage of voters consider politics to be ideology based, it is expected that the association between ideology and resistance to intergroup apologies by one's own government differs according to their level of political knowledge. We selected three issues of political apologies: colonial rule in Asian countries, comfort women, and the massacre of Korean people based on false rumors at the time of the 1923 Kanto Earthquake; thereafter, we conducted an online survey of a panel selected by Nikkei Research Inc. The results suggest that the relationship between ideology and resistance among voters to political apologies varies with the level of political knowledge, as expected. On the contrary, social dominance orientations (SDO) were associated with resistance to apology, regardless of their level of political knowledge. We then tested the reproducibility of this finding by conducting a follow-up test on registered users of a crowdsourcing service after conducting a preregistration. In addition, we also measured general attitudes toward personal apologies and neighboring countries victimized by Japan's colonialist policies as factors that might predict resistance to apologies even among the politically uninformed. The association between ideology, SDO, and resistance to governmental apologies was generally replicated in this study.
