The Discrepancy Between AI and Lived Experience
This section explores the core challenges identified in aligning computational health status representations with the nuanced, subjective lived experiences of individuals with chronic conditions.
18%
AI-Learned Phenotype Alignment with User Perception
Our study revealed that AI-generated learned phenotypes matched participants' self-assessments only 18% of the time. This highlights a significant challenge in aligning computational models with subjective lived experiences.
The 'Betrayal!' Phenomenon: Under-Reporting Symptoms
“Betrayal!” – HS6's reaction when AI suggested her health status was better than she perceived.
Participants often under-reported the severity of their symptoms due to stigma, self-doubt, and normalization of chronic pain. When AI models, designed to be supportive, then underestimated their health status, it led to feelings of frustration and 'betrayal', echoing experiences of invalidation from the healthcare system.
Lesson for Enterprise AI: AI systems must account for socio-cultural factors like stigma and self-doubt in self-reported data. Direct interpretation can perpetuate invalidation; human-centered design requires understanding the meaning behind reports, not just the data itself.
Building and Validating Temporal Health Status Models
This tab details the methodological approach taken to develop both learned and rule-based phenotypes, and how their efficacy and alignment with user perceptions were evaluated.

Phenotype Evaluation (Mixed-Methods User Study)
The development process involved aggregating rich self-tracked data, constructing two distinct phenotype models, and rigorously evaluating them through a mixed-methods user study to understand their alignment with lived experiences.
| Feature | Learned Phenotype Model | Rule-Based Phenotype Model |
|---|---|---|
| Methodology | Unsupervised probabilistic mixed-membership model; integrates multiple variables. | Rule-based mapping from a single Likert-scale question ('How was your day?'). |
| Complexity | More computationally complex. | Simple to compute on-the-fly. |
| Severity Assignment | More balanced over- and under-estimation. | Tended to underestimate illness severity (more optimistic). |
| Missing Classifications | Fewer missing classifications. | Many missing classifications if the key question was not answered. |
| Interpretability | Captures latent patterns, offering deeper insights into illness dynamics. | Provides coarse, interpretable categorization based on direct user self-assessment. |
| Alignment with User Perception | 18% direct match with user assignments. | 35% direct match with user assignments. |
A direct comparison of the two phenotype models highlights their differing strengths and weaknesses in representing subjective health states, emphasizing the trade-offs between simplicity and comprehensive data integration.
Valuing Imperfect AI: Pathways to Human-Centered Design
Even with misalignments, participants found value in AI as a reflection tool. This section outlines user perspectives and critical future directions for developing more human-centered AI systems in healthcare.
Validation
Key Perceived Benefit of AI for Patients
Despite misalignments, participants were optimistic about using such AI tools, valuing them as a 'sounding board' for self-reflection and validation, and as a means to communicate their health status more effectively with healthcare providers.
