Empirical investigation of personal epistemology has been conducted in the various branches of psychology and education. The range of labels to describe personal epistemology include epistemological beliefs, reflective judgement, ways of knowing, epistemological reflection, epistemological theories, beliefs and resources. Researchers interested in personal epistemology ask questions such as "How do we know what we know?" and "How do our beliefs about knowledge and knowing influence learning?" (Burr & Hofer, 2002).
