As part of citizenship education, the prevention of radicalization and extremism through education (PVE-E) is an urgent initiative of global educational policy. According to research, radicalized individuals, despite the ideology held, have mindsets that challenge equality and social justice. In this light, this study examines the intergroup mindsets of Finnish students aged 16-19 in vocational institutions through a mixed methods research survey (n = 383). Three distinct intergroup mindsets were found in a profile analysis. The findings demonstrate that the intergroup mindsets of the students are predominantly egalitarian, open-minded, and inclusive. However, there are also students whose mindsets are anti-egalitarian and pro-dominance, and for whom Finnishness is a marker of borders and social exclusion. If intensified and manipulated, the views of these youth may become radicalized with serious implications for national security and societal cohesion. We argue that in PVE-E, the focus on critical thinking must be complemented with transformative approaches that support the development of mindsets based on social justice and equality.
