- Ethnographic research observes behaviour in its natural context and fills in what people cannot, or do not know how to, put into words in an interview.
- The usual formats are the in-home visit, the shop-along, observation at the point of sale or service, and the guided diary.
- It is the right choice when the problem lies in habits, routines and context, and the wrong one when the decision needs representative figures.
- The sample is small and purposively chosen across profiles that differ in relevant ways; its value comes from depth, not numbers.
- Observation requires explicit consent, clear rules for photos and video, and an analysis that separates what was seen from what was interpreted.
1. The problem: what people say and what they actually do
A detergent manufacturer asks shoppers in a survey how much product they use per wash. The answers sit close to the dose printed on the pack. A handful of household visits shows something else: people pour by eye, ignore the measuring cap and add more when the laundry looks particularly dirty. Respondents did not lie in the survey. They described what they thought they did, or what they felt they ought to do. The gap between reported and actual behaviour is one of the oldest problems in research, and ethnographic research is the method built specifically to close it.
The same problem appears well beyond consumer markets. A town hall wants to know why residents do not use its online application service, even though the survey says most of them own a smartphone with internet access. A social programme wants to understand why families do not keep to a treatment schedule. Answers to direct questions are accurate but incomplete: they leave out the habits, the constraints inside the home, the moment at which someone gives up. These things are easier to see than to describe.
2. What ethnographic research is
Ethnography comes from anthropology, where researchers lived for months or years in a community to understand its culture. In market and social research the principle survives while the timescale shrinks: the researcher enters people's natural setting, watches them do the thing being studied, talks with them in that context and interprets the behaviour through the meaning it has for them. It is a form of qualitative research that combines observation with interviewing, rather than using either on its own.
Three features set it apart from other qualitative methods. The first is context: behaviour is studied where it takes place, with the real objects, space, people and interruptions. The second is flexibility: the researcher follows what emerges in the field instead of sticking to a fixed list of questions. The third is the participant's perspective: the aim is not to test the client's hypotheses but to understand the world as the observed person sees it, including the things the client did not know to ask about.
Observation as a technique comes in several forms. It can be structured, with a grid that fixes in advance what is recorded (for example, how long a shopper stands at the shelf), or unstructured, with the observer noting everything that seems relevant. It can be open, where people know they are being observed, or disguised, where they do not, as in mystery shopping. Ethnography proper is almost always open and fairly unstructured, because it depends on the participant's trust and explanations.
3. When it is the right choice, and when it is not
Ethnographic research fits problems rooted in behaviour people perform on autopilot and no longer notice: household routines, how food is prepared, how products are stored, how a form gets filled in. It fits when context matters more than opinion: a cramped kitchen explains a packaging choice better than any stated preference. It is valuable in the exploratory phase of a new project, before a questionnaire is written, because it shows which questions are worth asking and in what words people talk about the subject.
It is not the right tool when the decision needs numbers: what share of the population does something, how big the market is, how an indicator moves over time. Those questions need a survey with a probability sample. Nor does it suit behaviour that is rare, unpredictable or intimate, where a researcher's presence would be impossible or inappropriate. And it is a poor choice under a very tight deadline: recruiting for home visits, scheduling them and analysing the material take longer than a set of focus groups.
4. The usual formats: from home visits to shop-alongs
In practice the method is delivered in a few formats, each suited to a different kind of question.
- In-home visits: the researcher spends two to three hours in the participant's home, talks, asks to see where products are kept and observes a concrete activity: cooking, washing, using an appliance, paying the bills.
- Shop-alongs: the researcher accompanies the participant on a shopping trip, observes the route through the store, the moments of hesitation at the shelf and the exchanges with staff, then talks it through straight afterwards.
- Observation at the point of sale or service: the researcher watches, usually with a grid, how people move through a shop, a branch or a public service centre, where queues build up and what information they look for.
- Accompanied use: the participant uses a product or a digital service in front of the researcher and comments on what they are doing, which exposes the sticking points they would never mention in an interview.
- Guided diaries (or mobile ethnography): over one or two weeks participants record moments related to the topic through photos, messages or notes, and the researcher then discusses the diary with them.
Formats are often combined: a week-long diary followed by an in-home visit captures both the rhythm of habits and the depth of context.
5. Design: participants, guide, duration
The sample is small and purposively chosen. A typical project might, for example, include between 8 and 20 participants, selected to cover the profiles that differ in ways that matter for the problem: households with and without children, urban and rural, new and long-standing users, Romanian and Russian speakers. Statistical representativeness is not the goal; diversity of situations is. When the same pattern appears across several different profiles, the finding becomes solid; when a case contradicts the pattern, it deserves to be followed up, not discarded.
Recruitment uses a screening questionnaire, as with focus groups, but with an extra condition: the participant must accept a stranger in their home or on their shopping trip, and sometimes photographs of their space. This condition inevitably selects more open people, and the effect is recorded in the report.
The instrument is an observation and discussion guide, not a questionnaire. It sets the themes to cover, the activities to be seen and the objects to photograph with permission, but leaves room for the unexpected. For structured observation in shops, the guide becomes a grid with precise categories, and observers are trained to apply it in the same way.
6. Fieldwork: how observation unfolds
An in-home visit opens with a relaxed conversation about the household and its daily routine, moves on to the activity being observed and closes with questions about what was seen: "I noticed you put the bottle back in the cupboard rather than next to the sink. Why there?" These contextual questions are the core of the method, because they tie behaviour to its explanation while both are still fresh.
The biggest threat in the field is the observer effect: people behave slightly differently when watched. It cannot be removed, but it can be reduced. Longer visits help, because after the first hour participants slip back into their routine. A neutral manner helps too, with no signs of approval or disapproval. Diaries and observing several occasions show whether what was seen on the day of the visit was typical.
Field notes are written up on the day of the visit and keep three things apart: what was seen, what the participant said and what the researcher interprets. Photos and recordings are made only with the explicit agreement of everyone present, and faces and personal documents do not appear in client deliverables without separate consent.
7. Analysis: from field notes to decisions
The material from an ethnographic study is rich and messy: notes, transcripts, photographs, diaries. Analysis begins with coding, marking passages by theme, and continues by comparing cases: what all participants do, what only some do, and why. The output is not a list of quotes but a set of explained findings: behaviour patterns, the moments when a problem arises, the reasons behind them and the tensions between what people want and what their circumstances allow.
To become decisions, findings are translated into formats teams can use. A journey map shows the steps a person goes through from need to use, with the friction points marked. A set of profiles describes the types of behaviour observed. A list of opportunities links each problem seen to a possible change in product, packaging, communication or process, which is the kind of work done in strategic marketing consulting. When a finding needs to be quantified, it becomes a question in a later survey, and observation and survey complement each other.
8. Limits and common errors
The first limit is generalisation. Twelve visits show that a behaviour exists and explain why, but they do not tell you how widespread it is. A report that turns "eight of twelve participants" into a percentage for the whole population claims more than the method can support.
The second is interpretation. The same gesture can have different explanations, and researchers see through their own expectations. The remedies are several observers, discussing interpretations as a team and checking them with the participant during the visit.
The third is cost per participant, higher than for any other qualitative method, because each case requires travel, time and individual analysis. The common errors are predictable: visits too short for the participant to step out of the role of host; guides that turn into questionnaires and cancel out the advantage of observation; and reports full of attractive photographs with no explicit link to the decision that prompted the study.
Ethics need particular care, because the researcher enters private space. Informed consent is obtained from the participant and from other household members who appear in the observation, and a parent's consent is required for minors. Personal data, images included, are handled in line with Moldova's Law no. 133/2011 on personal data protection and the GDPR, and disguised observation is used only in public spaces and within the ICC/ESOMAR International Code. The details are covered in our article on research ethics and data protection.
9. Ethnographic research compared with other methods
| Method | What it captures | Where it takes place | Weak point |
|---|---|---|---|
| Ethnographic research | Actual behaviour, its context and its explanations | At home, in the shop, where the product is used | Cost per participant, does not generalise |
| In-depth interview | Motivations, decision histories, individual experience | Meeting room, office, online | Relies on what the person remembers and reports |
| Focus group | Opinions, shared language, reactions to ideas | Focus group facility or online | Group influence, reported behaviour |
| Structured observation and mystery shopping | Service standards, flows, behaviour at the counter | Point of sale or service | Sees what happens, not why |
| Survey | Frequencies, proportions, trends in the population | Face to face, telephone, online | Reported behaviour, no context |
The strongest projects do not rely on a single method. Observation identifies behaviours and the words people use, in-depth interviews or focus groups explore motivations, and a survey measures how widespread they are. If the problem is service quality across a network of outlets, disguised observation through mystery shopping is a better fit than ethnographic visits.
10. What to ask the agency
- An explicit link between the decision to be made and the behaviours to be observed.
- The proposed format (in-home visit, shop-along, point-of-sale observation, diary) and the reason for choosing it.
- Participant profiles, the number of cases per profile and the selection criteria.
- The observation and discussion guide, including the activities that must be seen.
- The length of each visit and how the observer effect will be reduced.
- Who does the observing: researchers with qualitative experience who speak the participant's language.
- The consent procedure, the rules for photos and video, and how personal data are protected.
- The deliverables: explained findings, a journey map and opportunities tied to the decision, not just notes and photographs.
Ethnographic research is the most direct way to see a product, service or programme through the eyes of the people who use it, in their real circumstances. Used at the right moment, usually before a survey or a redesign, it spares an organisation from decisions built on reported behaviour.
