Zaller's model of public-opinion formation portrays the average citizen as an automaton who responds unthinkingly to elite cues. That is, once people have received information from political elites, they tend to abide by whatever their respective cue-givers dictate, since rejecting information is more cognitively costly than simply accepting it. Empirical research in psychology on priming supports this view of the citizen as a passive receiver of information. For example, people are likely to be unconsciously influenced by subtle cues and they (...) tend to base their opinions on the accessibility of information in memory. However, some citizens, under certain conditions, may be ?active processors? of information: actively interpreting it, elaborating on its implications, and negotiating its meaning. Whether or not Zaller's model is an accurate representation of the process of public-opinion formation depends substantially upon the inclusiveness of the researcher's views about what constitutes public opinion and how to study its determinants.
