Sweden is often described as a highly secularized country, but we know little of the actual worldviews among youths in Swedish classrooms. The overarching aim of the quantitative study presented in this paper is to investigate ambiguous positions concerning supernatural beliefs among young Swedes, and to consider educational implications of these. The results highlight a central conclusion in the cognitive science of religion, namely that self-declared beliefs are not always aligned with people’s actual thoughts and experiences. These results provide Swedish RE-teachers with interesting opportunities for creating a space where pupils with secular and religious self-images can meet for existential discussions; thus, allowing pupils to use their personal experiences to better understand peers with other worldviews. The term *secular literacy* is moreover introduced to highlight the necessity of studying both secularity and religiosity as complex constructs, to avoid reinforcing the notion of an “Us” and a “Them”.
