When sociologists examine the content of sociological knowledge, they typically engage in textual analysis. Conversely, this paper examines the relationship between theory figures and causal claims. Analyzing a random sample of articles from prominent sociology journals, we find several notable trends in how sociologists both describe and visualize causal relationships, as well as how these modes of representation interrelate. First, we find that the modal use of arrows in sociology are as expressions of causal relationship. Second, arrow-based figures are connected to both strong and weak causal claims, but that strong causal claims are disproportionately found in U.S. journals compared to European journals. Third, both causal figures and causal claims are usually central to the overarching goals of articles. Lastly, the strength of causal figures typically fits with the strength of the textual causal claims, suggesting that visualization promotes clearer thinking and writing about causal relationships. Overall, our findings suggest that arrow-based figures are a crucial cognitive and communicative resource in the expression of causal claims.
