This paper explores the possibility of preventing prejudice among adolescents by promoting the analytical processing of social media content emerging from racial misinformation. Specifically, we propose, at this aim, an intervention that centers on recognizing stereotypical beliefs and other media biases about a group of people in misleading news. To better understand the variables that contribute to improving socio-analytical performance in the face of such misinformation, we investigated the influence of implicit associations as a tendency toward the automatic labeling of groups, as well as two dimensions of perceived self-efficacy in the face of misinformation, one active and one inhibitory. Our results demonstrate the presence of a negative link between affective prejudice and socio-analytical processing, and that this analytical performance toward misleading news is negatively related to the individual tendency toward implicit activation, and is also explained by the inhibitory factor of the perceived efficacy toward misinformation. The role of the active factor related to the perceived ability of fact-checking is not significant. This research suggests that education focused on the socio-analytical processing of misleading news in social media feeds can be an effective means of intervening in online affective prejudice among adolescents; the implications and limitations of our findings for future research in this area are discussed.
