“…Personality was assessed with a 25-item measure of the five-factor (Big 5) model of personality (Brody and Ehrlichman, 1998) on a 7-point scale (1 = not at all true of me and 7 = very true of me ). Based on the correlational findings observed in prior studies (Taylor and McFatter, 2003; Różycka-Tran et al, 2015), we particularly considered extraversion (e.g., talkative, outgoing; α = 0.79), neuroticism (e.g., anxious, worrying; α = 0.85), and agreeableness (e.g., warm, generous; α = 0.71). One’s perceived socioeconomic status (SES), which relates with zero-sum thinking (Różycka-Tran et al, 2015), was measured by a commonly used scale (e.g., Kraus et al, 2009; “What level do you think your household income belongs to?”).…”
