“…This hypothesis rests on the assumption that people tend to protect their political attitudes and not be readily open to persuasion attempts (e.g., Kunda, 1990; Lord et al, 1979). However, this hypothesis also expects that people’s political attitudes can change (e.g., Bryan, Dweck, Ross, Kay, & Mislavsky, 2009; Cohen, 2003; Jost, 2006; Landau et al, 2004; Munro, Zirpoli, Schuman, & Taulbee, 2013; Oppenheimer & Trail, 2010). Specifically, people’s existing attitudes may increase after exposure only to relevant moral frames of pro-attitudinal issues.…”
