Abstract
What political content do we pay attention to online? Diverse political information is essential for democratic competence, yet online media raises concerns about fragmented information diets. Research on selective exposure highlights how social media can foster ideological echo chambers, while other studies emphasize incidental exposure to diverse viewpoints. A critical measurement challenge is that public platform traces often observe engagement (e.g., likes or shares) more readily than lower-visibility forms of attention—i.e., what users notice or choose to read without necessarily interacting publicly. In this study, we address this gap with a social media clone platform that separately records attention and engagement. We ran the study in both the United Kingdom (once) and the United States (thrice). Across both contexts, we found that the ideology-engagement association is significantly larger than the ideology-attention association. This underscores the importance of measuring attention, rather than solely engagement, to accurately assess the diversity of online information diets.
