“…Unfortunately, causal mechanisms have tended to take the form of assumptions rather than tested hypotheses in bandwagon research. Promising evidence suggests that social-psychological theories such as the heuristic–systematic (Chaiken, 1987) and elaboration likelihood models (Petty and Cacioppo, 1986) hold water as bandwagon mechanisms (Areni et al, 1998, 2000; Mutz, 1992, 1997,1998; Roy et al, 2015). Mutz’s work in this vein is, again, not explicitly about the bandwagon effect, owing to her narrow conception of its meaning, but studies an essentially equivalent process.…”
