This is an early publication from my main current scholarly project. I am concerned that several streams of research and intellectual conversations are converging on the same conclusion: people just aren’t very thoughtful or rational about politics. This stance discourages efforts to enhance democracy and the public sphere. However, the most prevalent measurement tools–standard opinion surveys–are systematically biased against detecting the complexity and individuality of individuals’ political views. Various colleagues and I are experimenting with alternative quantitative methods that involve directly asking people about the connections among their distinct beliefs and analyzing the results as networks. This sole-authored article is a pilot study aimed at validating the method.


Individuals in a non-representative sample of 93 US progressives were asked which social outcomes they valued and then asked about the relationships among these opinions. Did each outcome provide a reason for a different one? Would each outcome cause a different one? If each outcome came to pass, would it make them more likely to support another outcome? Network diagrams derived from these responses represent portions of these individuals’ ideologies, understood as structures of political thought. Scrutiny of the network diagrams and analysis of the aggregate data suggest that most respondents carefully and reasonably identified relationships among their own ideas. Features of their networks predicted their assessments of five prominent politicians. This exploratory study paints a strikingly different picture of the sample than what would emerge from more conventional methods, such as factor analysis. Instead of a group that looks ideologically homogeneous on a unidimensional scale or that exhibits a low level of ideological coherence (because very few of their ideas are correlated), this method displays a collection of people who hold diverse and complex structures of thought. The method should be replicated with representative samples to explore the variation and significance of such structures.
