“…We focused on the relationship between studying economics and the development of narcissistic admiration and Mach because several studies on university education entertain the idea that tertiary business and economics education can influence students’ narcissistic and antisocial tendencies (e.g., Etzioni, 2015; Westerman, Bergman, Bergman, & Daly, 2012). This idea is based on (a) studies finding economics university students to be higher in narcissism (Westerman et al, 2012) and Mach (McLean & Jones, 1992; Skinner, 1981; but see also Li-Ping Tang, Chen, & Sutarso, 2008) than students in other majors and (b) studies suggesting that studying economics at university fosters immoral tendencies (for a review, see Etzioni, 2015). For example, students who attended a class on game theory became more cynical and less honest—which is highly consistent with Mach—over the course of one semester than students who attended an astronomy class (Frank, Gilovich, & Regan, 1993).…”
