The purpose of this study is to examine how physics students position themselves compared to other student groups on various attitudes and opinions relevant to the tradition of "scientific skepticism". Previous research has shown physics students identifying and having mindsets in line with the epistemic ideas from this philosophical tradition, promoting disbelief in epistemically unfounded ideas, and skeptical inquiry as a tool for evaluating claims. In this, we employ quantitative constructs testing conspiracy beliefs and supernatural beliefs along with established psychological constructs for social dominance orientation, and the conspiracy mentality questionnaire that have previously been shown to have interconnectedness. After showing several direct comparisons between different student groups, the paper also examines other elements that can influence "scientific skepticism", like education level, education type, and gender via multivariate regression analysis. The results suggest physics students tend to position themselves to the end of the spectrum on several constructs connected to scientific skepticism, both compared to students from the humanities and social sciences, and students from other STEM (science, technology, engineering, and mathematics) fields, and the regression analysis finds being a physics student contributes a statistically significant contribution along the tested dimensions. The paper discusses possible reasons for this and what this tells us about physics students and physics education.
