A theory of political belief system dynamics should incorporate causal connections between elements of the belief system and the possibility that belief systems are influenced by exogenous factors. These necessary components can be satisfied by conceptualizing an individual's belief system as a network of causally connected attitudes and identities which, via the interactions between the elements and the push of exogenous influences, produces the disparate phenomena in the belief systems literature. We implement this belief systems as networks theory in a dynamic Ising model and demonstrate that the theory can integrate at least six otherwise unrelated phenomenon in the political belief systems literature, including work on attitude consistency, cross-pressures, spillover effects, partisan cues, and ideological differences in attitude consensus. Our findings suggest that belief systems are not just one thing, but emerge from the interactions between the attitudes and identities in the belief system.

一个政治信仰体系动态理论应纳入信仰体系各要素之间的因果联系，以及信仰体系受外部因素影响的可能性。通过将个体的信仰体系概念化为一个由因果相连的态度和身份构成的网络，这些必要要素能够得到满足，该网络通过各要素之间的相互作用以及外部影响的推动，产生了信仰体系文献中的各种不同现象。我们在一个动态伊辛模型中实施这种将信仰体系视为网络的理论，并证明该理论能够整合政治信仰体系文献中至少六种原本不相关的现象，包括态度一致性、交叉压力、溢出效应、党派线索以及态度共识中的意识形态差异等方面的研究。我们的研究结果表明，信仰体系并非单一的事物，而是源自信仰体系中态度和身份之间的相互作用。所有代码均可获取：https://osf.io/aswy8/?view_only=99aff77909094bddabb5d382f6db2622 。
