This paper seeks to highlight the links and discrepancies between three contemporary theoretical fields. The first part is devoted to theories of mind and personal epistemology. Both fields deal with naive theories relating to the nature of knowledge and can be integrated within the concept of "folk epistemology" (Kitchener New Ideas Psychol 20:89-105, 2002). We argue that analyzing both domains from a developmental perspective may provide evidence for the origins of epistemological beliefs and the reasons for their evolution. The second part of the paper extends the discussion to the concept of metacognition and to its potential links with the two previously mentioned fields. In the past, theories of mind and metacognition have mainly developed as independent fields, but recent studies have highlighted a possible developmental lineage between them that needs further investigation. As the influence of the procedural component of metacognition (the regulation process) seems obvious in the personal epistemology perspective, we suggest that conducting more in situ studies will enable us to deepen our understanding of the links between the multiple components of the epistemological perspective and the reasons for epistemic change.
