This research examines how adolescents think about knowledge and knowing, evaluate competing sources of knowledge, trust certain sources of knowledge, justify knowledge, and approach certainty of knowledge, processes collectively referred to as “personal epistemology.” This project is a four-year, multi-method and multi-measure study in which students from grades 6, 8, 10, and 12 were interviewed about their views on knowledge and knowing. In this set of analyses, we examined the question of domain specificity in adolescent epistemic development and found that personal epistemology is not consistent across all domains, but rather, adolescents’ views about knowledge vary depending on the domain of knowledge that they evaluate. By comparing adolescents’ views on historical knowledge vs. scientific knowledge, we found that adolescents were more likely to trust sources of knowledge in science, to justify sources of scientific knowledge as more trustworthy and valid, and to view knowledge in science as more certain.

“What if you had two accounts of the causes of a war, one by a person who lived at that time, and another by a historian, a history expert, who didn’t live through the war, but who has researched it a lot. Which one would you find more believable?”

77% of 6th graders, 73% of 8th graders, and 36% of 12th graders chose contemporary.

Most Common Rationale for Choosing Contemporary

Grade Because Witness Personally Experienced it Because Historian’s Information Could Be Wrong
6th (n=20) 100% (n=20) 40% (n=8)
8th (n=24) 100% (n=24) 21% (n=5)
12th (n=9) 78% (n=7) 11% (n=1)
