Foreign and Regional Languages Make You Less Deontological

Previous studies have shown that foreign languages can change people's responses to moral dilemmas, making them more likely to choose harm (e.g., to kill one individual in order to save a few lives). Regional languages have also been shown to make sacrificial choices more likely. Regional languages are typically acquired early and used routinely among family and acquaintances, thus differing from foreign languages that are typically acquired later and used rather sporadically. Using a process dissociation procedure, we show in the present study that regional and foreign languages weaken the contribution of the deontological view in similar ways. Furthermore, the effects of both languages were modulated by proficiency, so that less proficient bilinguals showed a stronger decrease of the deontological tendency. These similarities suggest that the effects induced by both languages stem from what these languages have in common. Both languages are not experienced in contexts critical in forging moral views (e.g., public institutions, media, schools). We propose that the effects of foreign and regional languages stem from the lack of experience in such contexts.
