Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents. According to the Frontiersin.org review by Sara Riggare et al. (published 18 August 2026), the paper develops a four-phase framework (Questioning, Observing, Reasoning, Discovering) to assess whether self-tracking is measurement-only or genuine knowledge production. The primary keyword for this post is personal science qualitative analysis, and the pay-off is practical guidance: use an agency-based cycle and AI-assisted coding to show who "owns the question, " a distinction the Frontiersin.org authors call decisive for turning tracking into personal science. The short walkthrough below translates Riggare et al.'s numbers and definitions into stepwise methods for AI-enabled qualitative researchers.
Key Takeaways
According to the Frontiersin.org review by Sara Riggare et al. (published 18 August 2026), an agency-based four-phase framework distinguishes low-agency measurement from high-agency personal science and shows that only a minority of quantified self papers demonstrate full participant-led inquiry. The Frontiersin.org review found concrete counts and dates that make those distinctions reproducible.
- A Web of Science and PubMed search in April–May 2025 returned 721 records for the search term "quantified self, " of which 241 full papers were retained for analysis, according to Frontiersin.org (18 August 2026).
- Of the 241 retained papers, 46 used self-tracking as the data collection method and were analyzed for agency levels, per Frontiersin.org (18 August 2026).
- The 46 self-tracking papers split into 17 low-agency, 10 mixed-agency, and 19 high-agency studies, as reported in Frontiersin.org (18 August 2026).
- Riggare et al. argue that the key test of personal science is "who owns the question, " and they quote Catherine Elgin on agency: "Epistemic agents should think of themselves as, and act as, legislating members of a realm of epistemic ends, " as cited in Frontiersin.org (18 August 2026).
What Happened: How the Frontiersin.org review classified epistemic agency
Answer: Riggare et al.'s review in Frontiersin.org (published 18 August 2026) developed a four-phase personal science framework and applied it to the literature to classify levels of individual agency.
According to Frontiersin.org, the authors adapted Wolf and de Groot's personal science model into four phases (Questioning, Observing, Reasoning, Discovering) and operationalized three agency levels (low, mixed, high) to judge who performed each phase (Frontiersin.org, 18 August 2026).
According to Frontiersin.org, methodologically the review searched Web of Science and PubMed in April–May 2025 for the term "quantified self, " screened 721 unique records, and after screening retained 241 full texts for classification (Frontiersin.org, 18 August 2026).
According to Frontiersin.org, the authors applied a conservative, dual-review process with conflict resolution and coded the 46 self-tracking studies by asking whether each phase was performed by the individual or by researchers (Frontiersin.org, 18 August 2026).
Findings snapshot
| Date | Metric | Value | Implication |
|---|---|---|---|
| April–May 2025 | Search results for "quantified self" (Web of Science, PubMed) | 721 records | Large but heterogeneous literature, per Frontiersin.org (18 Aug 2026) |
| April–May 2025 | Full papers retained after screening | 241 papers | Corpus for conceptual mapping, per Frontiersin.org (18 Aug 2026) |
| April–May 2025 | Papers using self-tracking as data-collection method | 46 papers | Eligible for agency classification, per Frontiersin.org (18 Aug 2026) |
| 18 August 2026 | Breakdown by agency level among 46 papers | 17 low, 10 mixed, 19 high | Shows coexistence of measurement-only and participant-led personal science (Frontiersin.org) |
| 2018 and 2024 (years) | Publication trends | Peak in 2018 (38 papers); uptick in 2024 (13 papers) | Field shows hype-like pattern and shifting terminology, according to Frontiersin.org (18 Aug 2026) |
Implications for qualitative researchers doing personal science analysis
Answer: Qualitative researchers should treat personal science as a distinct, high-agency form of N-of-1 inquiry when participants initiate questions, as argued in the Frontiersin.org review (18 August 2026).
- Operationalize agency in your coding schema by mapping the four phases (Questioning, Observing, Reasoning, Discovering), following the Frontiersin.org framework (Riggare et al., 18 Aug 2026).
- Quantify participation: report counts or percentages of papers or participants fulfilling each phase, as Riggare et al. did with n=46 self-tracking papers (Frontiersin.org, 18 Aug 2026).
- Capture both quantitative traces and contextual notes: the Frontiersin.org review shows high-agency personal science blends objective logs and subjective interpretation, so design mixed-format coding (timestamps, logs, memos) that preserves context.
- Document ownership of the research question explicitly in methods sections and codebooks, because the Frontiersin.org authors identify "who owns the question" as decisive for classifying personal science (18 Aug 2026).
How Evidano helps AI-enabled qualitative analysis of personal science
Problem: Manual synthesis across mixed data streams
Solution: Use Evidano's thematic, content, frequency, and cross-segment analyses to automatically extract patterns across transcripts, logs, and spreadsheets.
This matches the Frontiersin.org finding that personal science combines objective measures and subjective interpretation, so combine time-series logs with open-text reflections in the same analysis pipeline.
Problem: Measuring "who owns the question" across cases
Solution: Train Evidano's custom code hierarchy to tag Questioning, Observing, Reasoning, and Discovering phases and compute frequency counts and co-occurrence networks to show where agency appears in your corpus.
Evidano supports transcription with custom dictionaries and PII redaction, which helps when converting interviews or diary audio into analyzable text for phase coding.
Problem: Scaling n-of-1 case aggregation without losing context
Solution: Use Evidano's AI chat over your documents and visualization tools to drill down from cohort-level patterns to individual timelines while preserving original quotes and metadata.
For implementation details see the Evidano features page for thematic analysis and visualization options.
FAQ: personal science qualitative analysis
What is personal science qualitative analysis?
Answer: Personal science qualitative analysis is the study of self-directed, N-of-1 inquiry where individuals pose questions, collect data about themselves, and interpret findings, as defined in the Frontiersin.org review (18 Aug 2026).
Riggare et al. (Frontiersin.org, 18 Aug 2026) emphasize that personal science differs from conventional qualitative research because the researcher and subject are the same person and the goal is actionable self-knowledge.
How do I measure epistemic agency in self-tracking datasets?
Answer: Measure epistemic agency by coding who performed each phase (Questioning, Observing, Reasoning, Discovering), following the Frontiersin.org four-phase framework (Riggare et al., 18 Aug 2026).
The Frontiersin.org review operationalized agency by assigning low, mixed, or high labels to n=46 self-tracking studies and recommends conservative coding rules when evidence is ambiguous (18 Aug 2026).
Can AI assist with coding Questioning and Discovering phases?
Answer: Yes, AI can accelerate tagging of phase-specific language but should be paired with human verification to respect situated context, a point consistent with the Frontiersin.org authors' emphasis on contextualized interpretation (18 Aug 2026).
Riggare et al. note that personal science reasoning often blends subjective and objective data, so an AI-assisted workflow that preserves verbatim quotes and allows human adjudication is recommended (Frontiersin.org, 18 Aug 2026).
Conclusion & Next Steps
Answer: Use the Frontiersin.org agency framework to make epistemic agency explicit in qualitative studies of self-tracking and apply AI-enabled tools to scale rigorous, contextual analysis.
Riggare et al.'s review (Frontiersin.org, 18 Aug 2026) shows concrete counts (721 search hits in April–May 2025; 241 retained; 46 self-tracking cases; 17/10/19 low/mixed/high agency) that you can reproduce in your own literature or case audits.
Next steps: (1) code your corpus for the four phases, (2) quantify agency across cases, and (3) use an AI-augmented platform to preserve quotes and timelines while producing cohort-level visuals.
