Abstract
Within the context of partisan selective exposure and attitude
polarization, this study investigates a mutually reinforcing spiral
model, aiming to clarify mechanisms and boundary conditions that affect
spiral processesinterpersonal agreement and disagreement, and the ebb
and flow of message receptions. Utilizing agent-based modeling (ABM)
simulations, the study formally models endogenous dynamics of cumulative
processes and its reciprocal effect of media choice behavior over
extended periods of time. Our results suggest that interpersonal
discussion networks, in conjunction with election contexts, condition
the reciprocal effect of selective media exposure and its attitudinal
consequences. Methodologically, results also highlight the analytical
utility of computational social science approaches in overcoming the
limitations of typical experimental and observations studies.
