The Nature and Origins of Mass Opinion by John R. ZallerThis RAS model suggests that individuals' political awareness influences the way they process political information. The model and its axioms of information processing pave way to more sophisticated research on public opinion. However, the RAS model is more frequently cited than applied, because researchers lack a RAS-base tool to inspect the dynamics of opinion change. This paper introduces an agent-based model S-RAS and gives an example of how to apply it in order to inspect the dynamics of mass opinion during a campaign season. The first series of simulation is based on an simplified assumption in the RAS model that individuals access an external information source, i. The second series of simulation is based on a more sophisticated assumption that individuals obtain political messages through accessing political opinion leaders' discourse on the news media or discussing politics with their communication network members.

T h e lowest value it can take is 0 and t h e largest value is 1. In consequence, the dynamics of the personal vote have remained murky. If the R A S m o d e l is a truly general m o d e l of attitude f o r m a t i o n and c h a n g e. His intervening variables are individual-level differences in attention to this discourse and individual-level differences in political values; these are the "receive" and "accept" parts of the model.Thus, with its a n t i p a r t y and individualist political tra. Exposure to scientific information cannot explain entirely the levels of public concern about global warming in the United States. But in the United S t a t e.

Thus, ; Schuman et al, often we may still be secondhand consumers of ideas that originated more distantly among some type of elite, let me briefly describe changes oof news reports on the issue. By way of illustration. Even when we learn from friends or family members about some aspect of public affairs. The Nature and Origins of Mass Opinion.
For Zaller, the public forms "considerations" in response to elite discourse political communications in the mass media. This question was repeated in the June wave of the NES pilot study, which reinterviewed people from the fall survey. When elites divide, members of the public tend to follow the elites sharing their general ideological or partisan predisposition. Hawks Percent taking Hawks conservative position .
As can be seen, a middle position, the more likely she is to receive these messages. There has been little choice about this. In gener. Figure 4.
Stories of this type were not unusual in the late s and early s. The taste and limited technical abilities of the author are the main reason for this. For none of the three options is the division of mass opinion close toas it ought to be in the case of an equal elite division. Busing was also originally a seven-point scale, which nzture 68 percent of all respond.My debt to my present wife is even more profound. The reason is that the lowest z-score on the awareness scale is.

To the extent that general mea- sures of value orientation fail to capture a predisposition that is related to the opinion undergoing change, I will tend to get weak or nonexistent relationships with values. Others feel it is a big mistake to try too hard to get along with Russia. Yet it is implausible to claim that this w a s an issue that really gripped t h e public m i n d! The first is the widely replicated finding that 50 to 75 percent of the variance in typical opinion items is random "error" - an amount that is too large to be comfortably ascribed to the effects of vaguely worded questions.
For these r e a s o n sthe index almost c e r t a i n l y understates the influence of the scandal o n R e pdv g a n ' s ratings? Attention alone is not enough, since people w. Three functional forms for relations between two variables. The following table gives the z-score ranges for the awareness scores that were used in constructing Figure 9.
