Overt Participant Observation: Advantages and Disadvantages

Last Updated on September 3, 2026 by Karl Thompson

Participant observation is where the researcher joins in with the group being studied and observes what they actually do. There are two versions of it, and the difference between them matters more than anything else on this page:

1. Overt participant observation — the group knows the researcher is a researcher
2. Covert participant observation — the group does not know, and the researcher is undercover

This post covers the theoretical, practical and ethical advantages and disadvantages of participant observation, gives four recent examples of overt studies, and ends with a full-mark AQA exam answer on why a researcher might choose overt over covert.

Participant observation is one of the main research methods in the research methods topic of A-level sociology. It comes up on Paper 3 in the theory and methods section, and on Paper 1 in the Methods in Context question, where you have to apply it to a topic in education. It is one of the methods students are asked to apply most often.

What participant observation is

Participant observation is closely related to the ethnographic method, or ethnography, which is an in-depth study of the way of life of a group of people.

Ethnography is traditionally associated with anthropology, where the anthropologist visits a usually foreign country, gains access to a group such as a tribe or a village, and spends several years living with them with the aim of uncovering their culture. The method involves watching what participants do, listening to them, having probing conversations and joining in with day-to-day tasks. It also involves looking at cultural artefacts such as artwork and written material where it exists, and at what religious rituals and popular stories reveal about the culture. Ethnographic research traditionally involves taking copious field notes, and the resulting monographs can take a year or more to write up.

To cut a long-winded definition short:

Ethnography = participant observation + a detailed written account of one’s findings.

Most participant observers combine their observations with other methods, most obviously unstructured interviews, and some add more formal questionnaire-based research towards the end of the study period. That makes many of these studies mixed-methods studies in practice. For A-level purposes, participant observation is still classified as a qualitative method.

Overt and covert participant observation

This distinction is the one examiners come back to, and it is worth learning as a pair rather than separately.

Overt observation is where the group being studied knows they are being observed and knows the researcher is doing research.

Covert observation is where the group does not know, and the researcher goes undercover.

Both have advantages and disadvantages, and neither is straightforwardly better. Overt research is more ethical because there is no deception, and it lets the researcher ask probing questions and combine observation with other methods. Covert research may be the only way to gain access to a deviant group, it can allow fuller immersion in the culture, and it avoids the Hawthorne Effect.

HOWEVER, covert research involves deceiving people who have not consented to being studied, and it is far more stressful for the researcher. Most of the ethical objections to participant observation are really objections to the covert version of it. For the full treatment of the covert method, including the ethics and the studies, see this post on covert participant observation — it covers deception, informed consent and the researchers who ended up committing crimes to keep their cover, which is a separate body of material from what follows here.

The advantages of participant observation

Theoretical advantages

The most significant advantage of both types of participant observation is the high degree of validity the method achieves. There are at least five reasons for this.

You observe what people do, not what they say they do. In contrast to most other methods, participant observation lets the researcher see behaviour directly rather than relying on a respondent’s account of their own behaviour, which may be flattering, forgetful or simply wrong.

It takes place in a natural setting. Respondents should act more naturally than they would in a laboratory or a formal interview. The Hawthorne Effect should be reduced, especially in covert research. You also get a feel for actions in their context, which might seem out of place in an artificial research environment.

Digging deep and gaining insight. The length of time ethnographers spend with a community means close bonds can form, which lets the researcher dig deeper than other methods allow and find out things that would be hidden to any other means of enquiry.

Verstehen, or empathetic understanding. Participant observation lets the researcher join the group and see things through the eyes — and the actions — of the people in it. Joining in produces empathy through personal experience. That closeness to people’s reality is what gives participant observation its uniquely personal, authentic data, and it is why interpretivists favour it.

Flexibility and generating new ideas. With a questionnaire, the researcher decides what is important before any data is collected. The problem is obvious: what if the questions the researcher thinks matter are not the ones the respondents think matter? Participant observation is far more flexible. The researcher enters with an open mind, and new situations can be followed up as they arise.

Practical advantages

There are few practical advantages, but participant observation may be the only way of gaining access to certain groups. A researcher turning up with a questionnaire to study a street gang is likely to be read as an authority figure and unlikely to be accepted.

Ethical advantages

Interpretivists prefer this method partly on ethical grounds, because it is respondent-led. It allows respondents to speak for themselves and avoids the master–client relationship that comes with more quantitative methods, where the researcher sets the terms and the respondent answers within them.

The disadvantages of participant observation

Theoretical disadvantages

Low reliability. It would be almost impossible for another researcher to repeat a participant observation study, because the study depends on the personal skills and characteristics of one lone researcher. Nobody else can reproduce Pearson’s relationships with Blackpool supporters or Khan’s position at St Paul’s.

Low representativeness. Sociologists using quantitative methods study large, carefully selected samples that provide a sound basis for generalisation. The groups in participant observation studies are usually unrepresentative, because they are accessed through snowball sampling and are therefore haphazardly selected.

Questionable objectivity. Critics question how valid participant observation really is, on the grounds that it lacks objectivity. It is very difficult for a researcher to avoid subjectivity and forming biased views of the group. Researchers also decide what is significant enough to record and what is not, which depends on their own values. In extreme cases researchers might go native, becoming so sympathetic to the group that they omit any negative analysis of its way of life.

The Hawthorne Effect. People act differently because they know they are being observed. Participant observers counter this by arguing that nobody can keep up an act for months on end — eventually people relax and behave normally. That defence is stronger for long studies than short ones.

It lacks a concept of social structure. By focusing on participants’ own interpretations of events, the method tends to ignore wider structures such as class, gender and ethnicity, which means it can only ever give a partial explanation. This is the standard Marxist and feminist criticism of interpretivist methods.

Practical disadvantages

The method is time consuming and expensive relative to the small number of respondents involved. It takes time to gain trust and build rapport, so it may be days, weeks or months before respondents relax in the researcher’s presence.

It requires observational and interpersonal skills that not everyone has. You need to be able to get on with people and to know when to take a back seat and when to probe.

Gaining access can be a problem. Many people do not want to be researched this way, and where covert research is concerned the researcher is limited by their own characteristics. Not everyone can pass as a Hells Angel.

Ethical disadvantages

Ethical problems are mainly limited to covert participant observation, where respondents are deceived and cannot give informed consent. Legality can also become an issue in covert research, where a researcher working with a deviant group may have to commit illegal acts to maintain their cover — Pearson is the standard example, and that case is covered in the covert participant observation post.

Why overt observation is often the better choice

Students often assume covert observation is automatically superior to overt, on the grounds that people behave more naturally when they don’t know they’re being watched. It isn’t that simple, and there are at least five reasons why overt might be the better choice:

1. You can ask awkward, probing questions. A covert researcher who starts asking searching questions about why the group does what it does will look strange very quickly.
2. You can combine it with other methods. Interviews, questionnaires and documents are all available to the overt researcher and closed off to the covert one.
3. You can take on the role of the ‘professional stranger’. Respondents sometimes tell an outsider things precisely because they know that person is not one of them.
4. It is less stressful and less risky. No cover to maintain, and nothing to lose if it slips.
5. Follow-up studies are possible. The overt researcher can go back years later. The covert researcher generally cannot.

Point 5 is worth dwelling on. Khan returned to St Paul’s School repeatedly after his fieldwork and interviewed alumni afterwards, because his participants knew who he was. Pearson could not have done that with the Blackpool supporters without an awkward conversation.

Examples of participant observation studies in sociology

Participant observation is one of the main methods on the A-level syllabus, and many of the examples in the textbooks are painfully out of date. The four studies below are all more recent, and all are overt. The best-known covert example, Pearson’s study of football supporters, is covered in full on the covert participant observation post.

Khan’s ethnography of an elite American high school

Most ethnographic work has been carried out with — or on — the poor and the marginalised. Shamus Khan’s work is a rare ethnographic study of an elite institution.

Khan describes the method plainly: ethnography means embedding yourself in the relations under study and spending long periods with your subjects. For him it meant getting a job at St Paul’s School, moving into an apartment on campus, and observing the daily life of the school. After his years there he returned many times and sought out alumni to interview.

Khan was a full member of the group he was observing, and his group knew he was doing research. In contrast to a covert study, this let him carry on collecting data long after the fieldwork ended.

Mears’s ethnography of the world of the fashion model

Ashley Mears (this may have been before she started her formal research)

Ashley Mears spent two and a half years in what she calls participant observation, or more accurately ‘observant participation’ — a term she borrows from Wacquant. She worked for two modelling agencies across the full range of modelling work, including five Fashion Weeks, hundreds of castings and dozens of jobs. She sat beside bookers at their table in the office, drank with them at their favourite pubs and spent time backstage at fashion shows. As she neared the end of the observation phase and withdrew from modelling work, she formally interviewed a sample of bookers, managers and accountants.

In contrast to Khan, Mears puts the observation before the participation, which suggests she was less immersed in the day-to-day life of her group than Khan was.

Sampson’s research on international seafarers

Helen Sampson boarded her first cargo ship in April 1999. Contrary to her fears, the Swedish and Filipino crew welcomed her, and for forty-two days she lived and worked alongside them — painting the ship, going ashore to seamen’s bars, and joining in with their social life.

Sampson’s study won Thinking Allowed’s first ethnography award in 2014.

This is what Bryman calls a ‘participating observer’ rather than a ‘full member’. Sampson was working with the men on a very temporary basis, not becoming one of them.

Lora-Wainwright on living with pollution in rural China

Anna Lora-Wainwright spent four years, from 2009 to 2013, studying how people in rural China cope when they know severe pollution is damaging their health.

This is not ordinary pollution. She studied three villages, all dealing with the effects of large-scale industrial pollution from heavy manufacturing or waste disposal — one with phosphorus pollution, one with zinc and lead, and one with electronic waste. Guiyu, the last of the three, is known as the world’s largest e-waste site. All three villages report cancer deaths well above the national average.

Her focus was on how people responded to knowing they faced a significant cancer risk: how they organised and protested, but also how they simply coped day to day, living with water that would give them cancer if they drank it. She also looked at how this connects to the Chinese government’s industrialisation agenda and its preference for keeping such reports quiet.

Note how far the method stretches — from an elite American boarding school to a Chinese e-waste village, using essentially the same technique.

A note on how much ‘participation’ counts

The first four examples above are drawn from Bryman’s research methods textbook, which ranges twenty-three studies on a scale running from ‘full member’ through ‘partially participating observer’ down to ‘non-participating observer with interaction’.

Students often assume the famous studies are the most immersive ones, and it is worth knowing that they are not. Venkatesh’s Gang Leader for a Day sits in Bryman’s ‘minimally participating observer’ category, seventeenth of twenty-three, which puts it closer to a non-participant study than a full ethnography. Having read it, I can see his point.

Participant observation and Methods in Context (Paper 1)

On Paper 1 you may be asked to apply participant observation to a topic in education — the Methods in Context question is worth 20 marks and it is the question students find hardest on the paper.

The mark scheme rewards two things, and in this order. First, the method — the theoretical, practical and ethical issues covered above. You can reach the middle mark band on the method alone, without applying it to the topic at all. Second, the application — how those issues change when the group being researched is pupils, teachers or parents, and when the setting is a school.

The practical, ethical and theoretical framing is not decoration; it is how the mark scheme is organised, which is why every advantage and disadvantage on this page is labelled with one of the three.

Two worked examples of this question type:

• Evaluate the strengths and limitations of using participant observation to investigate pupil exclusions
• Evaluate the strengths and limitations of using non-participant observation to investigate pupil behaviour in schools (20)

Exam practice: outline and explain two advantages of overt participant observation (10 marks)

This 10-mark, no-item question could appear at the end of either Paper 1 or Paper 3. Below I consider a top-band answer, published by the AQA, which achieved 10 out of 10.

If you want to attempt this yourself before reading the answer, everything you need is above.

The question (no item)

Outline and explain two advantages of choosing overt participant observation as a source of data compared with covert participant observation (10)

The mark scheme

Note: there are no marks for evaluation on the 10-mark no-item questions. There are on the ‘analyse with the item’ 10-markers, which is a different question type with different assessment objectives. This is the single most confused distinction on the paper.

Student response

One advantage is that participants are aware you are researching them and so you’re able to write down notes about what you are observing and record it. However, with covert PO you are unable to do so because it would be suspicious, especially if you are observing dangerous ways of life. For example, Venkatesh’s required covert PO as he was unable to write down all the information and relied on retrospective data – from his memory. This means the data could lack validity because he could have forgotten less important aspects from the observation. This issue doesn’t arise with overt observation and so the data is more likely to be valid.

Overt PO is more objective and can be ethical. The participants are aware that the data is for a study and publication and they are less likely to withdraw. Whereas with covert PO, informed consent has not been collected and participants, after realising they have been deceived may choose to withdraw and not allow the researchers to use the data collected. This means that the data from covert PO may go unpublished and the researcher may have to reconduct another research method, wasting time and energy.

Examiner commentary (10/10 marks)

KT’s commentary

It looks as though the examiners just want you to compare overt with covert explicitly, point by point. Simple, really — punishingly simple.

And note what happened to case studies. Whatever your teacher told you about needing named studies, this answer names exactly one, in passing, and still takes full marks. The comparison is what earns the credit, not the reading list.

The structural lesson is that each of the two points does the same three things: states the advantage, explains why covert can’t do it, and says what that means for the data. Do that twice and you have ten marks. Students lose marks here by describing overt observation at length without ever mentioning covert, which answers a question that wasn’t asked.

This post has been written primarily for students studying the research methods topic as part of the AQA’s A-level sociology course, which is examined on Paper 1 and Paper 3.

For the covert version of this method — the examples, the ethics, and why researchers keep ending up on the wrong side of the law — see Covert Participant Observation: Examples and Ethics. Covert PO is a separate examinable sub-topic with its own studies and its own ethical problems, and it is worth reading as a pair with this post.

The obvious contrast is Non-Participant Observation, where the researcher watches without joining in, which trades validity for reliability.

Paul Willis’s Learning to Labour is the participant observation study most often used in education answers, and is worth knowing in detail for Methods in Context.
