Bracketing and Epoché: Making and Defending Your Suspension of Assumptions

Bracketing (the applied term) and epoché (the philosophical one Edmund Husserl coined it from) both name the same basic move: a researcher deliberately sets aside their own assumptions, prior knowledge, and expectations about a phenomenon so that participants’ accounts can be examined on their own terms. The problem most methods sections have with it is not understanding the concept — it is that “the researcher bracketed her assumptions” is a claim, not evidence. A reviewer (or a dissertation committee) has no way to check a sentence like that against anything. This guide treats bracketing as a documentable research act with a timeline — a memo written before data collection, revisited during analysis — rather than a one-line disclosure, and covers what a methods section actually needs to show to make the claim defensible.

What Bracketing and Epoché Actually Mean

Husserl’s original epoché is a philosophical suspension of the “natural attitude” — the unexamined assumption that the world exists exactly as it appears — to get at the structure of conscious experience itself. Applied qualitative research borrows the move but narrows it: bracketing is the researcher setting aside their own prior experience, professional knowledge, and expectations about the specific phenomenon under study, so those don’t pre-shape data collection or analysis. The most widely used applied version is Clark Moustakas’s transcendental phenomenology (Phenomenological Research Methods, 1994), which formalizes epoché as an explicit first step, followed by horizonalization and textural-structural synthesis. For the full method these steps belong to, see CASRAI’s Phenomenological Research guide — this page goes deep on the bracketing/epoché step specifically, not the whole method.

Why It’s a Live Methodological Debate, Not Settled Procedure

Whether bracketing is even achievable splits phenomenology’s major schools, and a methods section that ignores the split is making a claim the researcher’s own cited tradition may not support:

• Descriptive/transcendental phenomenology (Husserl, Moustakas). Treats disciplined bracketing as achievable, or achievable enough to be methodologically useful — the researcher can substantially, if not perfectly, set assumptions aside through deliberate practice.
• Hermeneutic phenomenology (Heidegger, and Max van Manen’s applied version in Researching Lived Experience, 1990). Rejects presuppositionless bracketing outright. Heidegger’s position is that understanding always proceeds from a “fore-structure” — the interpreter’s prior knowledge is not noise to eliminate but the necessary starting point of interpretation (the hermeneutic circle). Van Manen’s applied method uses the hermeneutic circle instead of an epoché step.
• Interpretative Phenomenological Analysis (IPA). Treats bracketing as an aspiration to be reflexively managed, not a clean, achievable reset — see CASRAI’s IPA guide for how this plays out specifically when bracketing prior cases during cross-case analysis.

The practical implication: “I bracketed my assumptions” is not a defensible claim in the abstract — it’s only defensible relative to a stated tradition. A hermeneutic-phenomenology study that also claims full presuppositionless bracketing is making two incompatible claims in the same methods section, and that inconsistency is exactly the kind of thing a careful reviewer catches. State which stance the study takes, and write the rest of the section to match it.

The Practical Version: Three Checkpoints, Not One Sentence

Treated as a single retrospective sentence, bracketing produces nothing checkable. Treated as a practice with a timeline, it produces a paper trail. Three checkpoints cover the practice as it’s actually done and documented:

When	What happens	What it produces
Before data collection	The researcher writes a bracketing memo: prior experience with the phenomenon, anticipated findings, assumptions being set aside — before recruiting or interviewing anyone.	A dated memo, written and timestamped before fieldwork begins — the single piece of evidence that most directly supports the claim.
During data collection	Some designs add a bracketing interview: a peer or supervisor interviews the researcher using the same interview guide that will be used with participants, surfacing assumptions the memo alone might miss before real interviews start.	Notes or a transcript from the bracketing interview, referenced in the audit trail.
During analysis	The researcher revisits the memo before and during coding, explicitly comparing emerging codes/themes against what the memo predicted, and notes where the two diverge or where the memo’s assumptions appear to be shaping a coding decision.	Dated reflexive-journal entries showing the comparison actually happened, not just that a memo exists somewhere.

The middle and third columns are what turn bracketing from an assertion into a documented practice. A memo that exists but is never referenced again during analysis supports a weaker claim than one the researcher demonstrably returned to.

Building a Bracketing Memo

A bracketing memo is a working document, not a manuscript section — it doesn’t get published in full, but its existence, timing, and how it was used are what the methods section draws on. A memo that does real work usually answers five questions concretely, not with a generic disclaimer that bias exists:

1. What is my personal or professional experience with this phenomenon? Named specifically — clinical role, prior research on an adjacent topic, lived personal experience — not a vague “I have a background in this area.”
2. What do I already expect to find? Written as concrete anticipated findings, stated plainly enough that they could later be checked against what participants actually said.
3. What theoretical or disciplinary lens am I bringing? The literature, training, or prior framework most likely to supply ready-made categories before the data has a chance to.
4. What language or categories am I tempted to impose rather than let emerge? Specific terms or framings from the researcher’s own background that could substitute for participants’ own words if not watched for.
5. What would it mean if my findings simply confirmed what I already believed? A concrete check the researcher commits to in advance — e.g., treating a fully-confirming result as a prompt to re-examine whether bracketing actually held, rather than as validation.

Illustrative example only — a composite excerpt written to show structure, not drawn from or attributed to any real study, author, or institution.

I spent six years as a hospice social worker before starting this study of family decision-making at end of life. I expect participants to describe conflict between family members as the central difficulty, because that was the dominant pattern I saw professionally — I need to watch for reading conflict into accounts that are actually about something else, such as logistical strain or grief expressed as irritability. I am also bringing family-systems theory as a lens, which readily supplies terms like “triangulation” and “enmeshment”; I will flag any point where I catch myself reaching for that vocabulary before a participant has used comparable language themselves.

What a Methods Section Needs to Show to Defend It

A single sentence claiming bracketing occurred is the pattern reviewers increasingly flag as disclosure without evidence — the same failure mode CASRAI’s Reflexivity and Positionality Statements guide documents for reflexivity claims generally. A defensible methods-section treatment of bracketing typically covers:

• Which tradition, and which stance on achievability. Name the phenomenological approach used (transcendental, hermeneutic, IPA) and be explicit about whether epoché is treated as achievable or as an aspiration reflexively managed — don’t claim more certainty than the cited tradition supports.
• When the memo was written. Before data collection, not reconstructed afterward from memory once the manuscript is being drafted — a memo written retrospectively documents recollection, not bracketing.
• How it was revisited. Specifically during analysis/coding, not only at the start of the study — this is the difference between a one-time gesture and an ongoing practice.
• What evidence exists. The memo itself (dated), any bracketing-interview notes, and reflexive-journal entries showing the comparison against emerging codes actually happened.

This maps directly onto the reporting checklists most qualitative journals already require: COREQ’s “Research team and reflexivity” domain and SRQR’s researcher-characteristics-and-reflexivity item both ask for exactly this kind of evidence trail, not a bare assertion — see CASRAI’s COREQ and SRQR guide for the full checklist items.

Bracketing vs. a Reflexivity Statement: Not the Same Thing

The two get conflated because they address related concerns, but they’re not interchangeable:

	Bracketing / epoché	Reflexivity statement
Scope	A phenomenological-method-specific practice: setting aside prior assumptions about the specific phenomenon under study.	A broader disclosure, used across qualitative traditions generally: the researcher’s social position and its influence on the study as a whole.
Where it lives	A working memo (and possibly a bracketing interview), not itself published in full.	A written paragraph or section that does appear in the manuscript.
What it’s evidence for	That assumptions about the phenomenon were surfaced and monitored, specifically for phenomenological designs.	That the researcher’s social location and its likely effects were considered, for any qualitative design.

In practice, a phenomenological study usually needs both: the bracketing memo as the working practice, and the published reflexivity/positionality statement as the manuscript artifact — with the memo’s existence and timing cited as part of what the reflexivity statement draws on. See CASRAI’s Reflexivity and Positionality Statements guide for the template and worked examples of that published artifact.

Common Mistakes

• Treating bracketing as a pre-study checkbox. A memo written once before recruitment and never referenced again supports a much weaker claim than one demonstrably revisited during coding.
• Claiming full presuppositionless bracketing inside a hermeneutic design. Van Manen’s hermeneutic phenomenology explicitly uses the hermeneutic circle instead of bracketing; asserting a clean epoché while citing van Manen is an internal contradiction a careful reviewer will catch.
• No dated memo or evidence trail. Without a timestamp before data collection, there is no way to distinguish genuine advance bracketing from a plausible-sounding paragraph written after the fact.
• Confusing phenomenon-bracketing with IPA’s cross-case bracketing. IPA’s practice of setting aside earlier cases’ emerging themes while analyzing the next transcript is a related but distinct, analysis-stage move — see the IPA guide for that specific procedure.

Frequently Asked Questions

What is bracketing in qualitative research?

Bracketing is the practice of a researcher deliberately setting aside their own prior assumptions, knowledge, and expectations about a phenomenon so that participants’ accounts can be examined on their own terms rather than filtered through the researcher’s existing beliefs. It is most closely associated with phenomenological research, particularly Clark Moustakas’s transcendental phenomenology.

What is epoché?

Epoché is Edmund Husserl’s original philosophical term for suspending the “natural attitude” — the unexamined assumption that the world simply is as it appears — in order to examine the structure of conscious experience directly. Applied qualitative bracketing borrows this move and narrows it to a specific research phenomenon rather than experience in general.

Is it actually possible to fully bracket your assumptions?

This is genuinely contested. Descriptive/transcendental phenomenology treats disciplined bracketing as achievable; hermeneutic phenomenology (following Heidegger) argues presuppositionless bracketing is impossible, since understanding always proceeds from prior knowledge. Most current applied guidance, including IPA, treats bracketing as an aspiration to be reflexively managed and documented rather than a clean, fully achievable reset.

What is a bracketing interview?

A bracketing interview is when a peer or supervisor interviews the researcher using the same interview guide that will be used with study participants, before data collection with participants begins — the goal is to surface assumptions and expectations the researcher might not identify through self-reflection alone.

Do I need a reflexivity statement if I already wrote a bracketing memo?

Usually yes, and they serve different purposes. The bracketing memo is a working document specific to phenomenological method; the reflexivity/positionality statement is the manuscript-facing artifact most qualitative reporting guidelines (COREQ, SRQR) expect, and typically draws on the bracketing memo as part of its evidence rather than replacing it.

Does every qualitative study need bracketing?

No — bracketing in this specific sense is a phenomenological-method practice. Other qualitative traditions (grounded theory, ethnography, general thematic analysis) use reflexivity statements and reflexive journaling to manage researcher influence, but don’t necessarily use a formal pre-study epoché step in Moustakas’s sense.
