Research Guide: Epistemic Agency in Self-Tracking

This post shows qualitative researchers and UX teams how to operationalize the concept of epistemic agency in self-tracking using AI-enabled methods. Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents for thematic, frequency, and cross-segment patterns. According to the Frontiersin.org review by Sara Riggare (published 18 August 2026), a literature search in April–May 2025 using the term “quantified self” returned 721 records and the authors retained 241 papers for full-text analysis, of which 46 used self-tracking as the data-collection method (Frontiersin.org). Read on for an SEO-friendly summary, an extractable snapshot table of the key numbers, practical implications for qualitative teams, and exactly how to map the Frontiers framework into Evidano workflows.

Key Takeaways

According to the Frontiersin.org review by Sara Riggare (published 18 August 2026), the paper develops a four-phase framework (Questioning, Observing, Reasoning, Discovering) and uses it to classify 46 self-tracking studies into low-, mixed-, and high-agency categories (Frontiersin.org).

721 records were identified in an April–May 2025 search and 241 full papers were retained for analysis, of which 46 used self-tracking as the data-collection method (Frontiersin.org, 18 August 2026).
Of the 46 self-tracking studies, 17 were classified as low-agency, 10 as mixed-agency, and 19 as high-agency according to the four-phase framework (Frontiersin.org, 18 August 2026).
The Frontiers review emphasizes that the central distinction is “who owns the question, ” and quotes Catherine Elgin: “Epistemic agents should think of themselves as, and act as, legislating members of a realm of epistemic ends” (Frontiersin.org, 18 August 2026).

What happened and how the framework works

Answer: Sara Riggare's Frontiersin.org conceptual review (published 18 August 2026) applied a four-phase personal science framework to characterize levels of epistemic agency across the literature.

According to the Frontiersin.org article by Sara Riggare (18 August 2026), the authors adapted the personal science cycle into four phases (Questioning, Observing, Reasoning, Discovering) and defined three agency levels: low, mixed, and high.

According to the Frontiersin.org methods section, the authors searched Web of Science and PubMed in April–May 2025 for the term “quantified self, ” retrieved 721 unique records, screened down to 241 full papers, and identified 46 papers where self-tracking was the data-collection method.

According to the Frontiersin.org results (18 August 2026), low-agency articles treat participants primarily as data suppliers, mixed-agency articles show participant negotiation and partial ownership, and high-agency articles show the full self-directed cycle with participants often co-authoring publications.

Direct quote: The Frontiersin.org article frames the core distinction succinctly: “who owns the question” is what turns measurement into personal knowledge (Sara Riggare, Frontiersin.org, 18 August 2026).

Findings Snapshot

Date / Search	Metric	Value	Implication
April–May 2025 (search)	Records retrieved	721	Large initial corpus using the term “quantified self”; suitable for mixed-methods screening (Frontiersin.org, 18 Aug 2026).
After screening (April–May 2025)	Full papers retained	241	Focused corpus for conceptual/theory synthesis (Frontiersin.org, 18 Aug 2026).
Final analytic subset	Papers using self-tracking as data collection	46	Narrow set where epistemic agency can be meaningfully assessed (Frontiersin.org, 18 Aug 2026).
Within the 46 studies	Low / Mixed / High agency counts	17 / 10 / 19	Evidence that roughly 41% of self-tracking studies exhibit high individual agency (Frontiersin.org, 18 Aug 2026).
Publication metrics noted	2018 peak	38 articles	Term usage peaked in 2018; 2024 had 13 and 2021 had 14 papers, indicating variable terminology over time (Frontiersin.org, 18 Aug 2026).

Implications for qualitative researchers and UX teams

Answer: Use the four-phase framework (Questioning, Observing, Reasoning, Discovering) to design data collection and to code for agency, because the Frontiersin.org review shows that agency alters what counts as knowledge (Sara Riggare, Frontiersin.org, 18 Aug 2026).

Qualitative teams should code transcripts and diaries for who initiated Questioning, who defined Observing protocols, who performed Reasoning, and who authored Discovering, because the Frontiersin.org dataset classified 46 self-tracking studies on those exact phases (Frontiersin.org, 18 Aug 2026).

When building interview guides, explicitly ask participants about method choices and sharing practices, because the Frontiersin.org review found that high-agency work more often shares methods and learnings rather than just raw data (Frontiersin.org, 18 Aug 2026).

For UX teams evaluating wearables, tag interactions that enable user-defined goals and data export, because the Frontiersin.org high-agency cases often required custom exports or manual logs to support personal science reasoning (Frontiersin.org, 18 Aug 2026).

How Evidano helps translate the Frontiers framework into practice

Problem: Hard to detect agency in mixed datasets

Answer: Detecting epistemic agency requires thematic, temporal, and actor-level coding; Evidano automates and surfaces those patterns.

Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, and documents by producing thematic, content, frequency, and cross-segment analyses.

Practical mapping: use Evidano to tag evidence of Questioning (who posed the problem), Observing (who collected and how), Reasoning (who ran analyses), and Discovering (who published or shared).

Problem: Manual n-of-1 syntheses are slow

Answer: Automate n-of-1 pattern detection and comparison across participants with Evidano visualizations and co-occurrence networks.

Evidano can ingest interview transcripts, device logs, and survey open-ends and produce aligned timelines so researchers can compare Reasoning steps across participants without manual spreadsheet merging.

Feature link: See how to operationalize coded workflows on the Evidano features page (Evidano Features).

Problem: Sharing methods and reproducible documentation is ad hoc

Answer: Standardize method and findings documentation with Evidano's exportable, hierarchical codebooks and AI chat over your documents.

Evidano supports structured outputs that document Questioning→Observing→Reasoning→Discovering steps so personal science projects can be transparently shared as methods, not just as data dumps.

If you need conversational, queryable access to participant artifact collections, consider Evidano's AI chat workflows (Evidano AI Chatbot).

FAQ: epistemic agency in self-tracking

What is epistemic agency in self-tracking?

Answer: Epistemic agency in self-tracking is the individual capacity to pose questions, design observation, analyze their own data, and articulate discoveries about themselves.

The Frontiersin.org review by Sara Riggare (18 August 2026) uses that exact operational definition and frames agency as who controls each phase of the inquiry (Questioning, Observing, Reasoning, Discovering).

How did the Frontiers review measure agency levels?

Answer: The authors coded each paper for whether the individual performed each of the four phases and then assigned low, mixed, or high agency conservatively.

According to Frontiersin.org (Sara Riggare, 18 Aug 2026), Observing was present in all 46 included self-tracking studies by definition, and high-agency status required evidence that the individual also led Questioning, Reasoning, and Discovering.

Which quantitative indicators matter for reporting agency in publications?

Answer: Report who authored the research question, who collected the measurements, who ran analyses, and who was involved in dissemination.

The Frontiersin.org review (18 Aug 2026) flagged co-authorship of participants and documentation of methods sharing as strong indicators of high agency.

Can AI tools like Evidano help audit epistemic agency?

Answer: Yes, AI-assisted qualitative platforms can accelerate coding for agency markers and produce reproducible summaries.

Using Evidano, teams can run thematic extraction for phrases indicating ownership (for example “I wanted to know” or “I exported my data”) and quantify the presence of Questioning, Reasoning, and Discovering across cases to create an agency index.

Are there ethical concerns when supporting personal science?

Answer: Yes, personal science raises data security, validity, and potential harm concerns and may fall outside formal ethical oversight.

The Frontiersin.org authors recommend infrastructure, recognition, and ethical guidance for personal science projects; research teams should treat personal science outputs as non-diagnostic and prioritize participant consent and data protection (Frontiersin.org, 18 Aug 2026).

Conclusion & Next Steps

The Frontiersin.org conceptual review by Sara Riggare (published 18 August 2026) gives qualitative teams a practical four-phase lens for measuring epistemic agency in self-tracking studies and shows that 19 of 46 analyzed self-tracking papers displayed high individual agency (Frontiersin.org).

Researchers and product teams should code for who initiates questions and who authors discoveries, and align study documentation to enable reproducible n-of-1 reasoning.
