🤖 AI Summary
Interactive visualization systems often suffer from presence bias, overlooking information absent from the display that users nonetheless expect to see, thereby hindering the formation of a complete mental model of the data. This study investigates how reference frames—global baselines versus concrete exemplars—and prompting strategies influence users’ ability to identify missing categories across three domains: energy, wealth, and political regimes. Through controlled experiments integrating methods from cognitive psychology and interactive visualization techniques, the research demonstrates that reference frames grounded in concrete exemplars are significantly more effective than global baselines in facilitating the detection of missing information. Furthermore, active prompting mechanisms markedly enhance users’ awareness of such omissions. These findings offer empirical support and practical guidance for designing expectation-driven visualizations that better align with users’ cognitive processes.
📝 Abstract
Interactive systems that explain data, or support decision making often emphasize what is present while overlooking what is expected but missing. This presence bias limits users'ability to form complete mental models of a dataset or situation. Detecting absence depends on expectations about what should be there, yet interfaces rarely help users form such expectations. We present an experimental study examining how reference framing and prompting influence people's ability to recognize expected but missing categories in datasets. Participants compared distributions across three domains (energy, wealth, and regime) under two reference conditions: Global, presenting a unified population baseline, and Partial, showing several concrete exemplars. Results indicate that absence detection was higher with Partial reference than with Global reference, suggesting that partial, samples-based framing can support expectation formation and absence detection. When participants were prompted to look for what was missing, absence detection rose sharply. We discuss implications for interactive user interfaces and expectation-based visualization design, while considering cognitive trade-offs of reference structures and guided attention.
