I have attend a few PhD VIVA VOCE and I hear Panelists asking about the researcher's positionality. Many times, the candidates positionality is contrasted with the philosophy behind his/her study in terms of epistemology and ontology.
Nicholas Isaac Mukwana
It's more likely the other way around: one's positionality may affect one's epistemological and ontological leanings or commitments. However, I think Karl Mannheim's distinction between particular and total ideologies (vide his classic Ideology and Utopia) is useful for analysing and characterizing positionality, since what people say and expressly believe is often at odds with their behavior and social function.
Yes, epistemology and ontology significantly influence one's positionality, particularly in how individuals understand and interpret the world around them.
In summary, epistemology and ontology are foundational to how individuals position themselves in relation to knowledge and reality, shaping their perspectives, interactions, and interpretations of the world.
