Evidotes: Integrating Scientific Evidence and Anecdotes to Support Uncertainties Triggered by Peer Health Posts

2026-02-18

AI Summary

This study addresses the challenge of mitigating uncertainty and emotional distress experienced by users when engaging with peer health narratives, where diverse informational needs often remain unmet by existing approaches. To this end, the authors propose an information augmentation framework that uniquely integrates scientific evidence with personal anecdotes through three optional interpretive lenses—“Deep Dive,” “Positive Focus,” and “Big Picture”—enabling dynamic, context-sensitive synthesis of content. This synergy fosters informational symbiosis: anecdotes enhance the accessibility and contextual relevance of research findings, while scientific evidence facilitates the curation and generalization of personal stories. In a user study with 17 individuals managing chronic conditions, the framework significantly improved information satisfaction (from 3.2 to 4.6) and reduced emotional burden (from 3.4 to 1.9), thereby strengthening users’ capacity to navigate health-related uncertainty.

Abstract

Peer health posts surface new uncertainties, such as questions and concerns for readers. Prior work focused primarily on improving relevance and accuracy fails to address users' diverse information needs and emotions triggered. Instead, we propose directly addressing these by information augmentation. We introduce Evidotes, an information support system that augments individual posts with relevant scientific and anecdotal information retrieved using three user-selectable lenses (dive deeper, focus on positivity, and big picture). In a mixed-methods study with 17 chronic illness patients, Evidotes improved self-reported information satisfaction (3.2->4.6) and reduced self-reported emotional cost (3.4->1.9) compared to participants' baseline browsing. Moreover, by co-presenting sources, Evidotes unlocked information symbiosis: anecdotes made research accessible and contextual, while research helped filter and generalize peer stories. Our work enables an effective integration of scientific evidence and human anecdotes to help users better manage health uncertainty.
