IB Psychology HLTopic 6 — CultureHL extensionCore idea~9 min read
Why Culture Matters in Psychology
Culture is one of the three HL extensions, and it shows up in almost every Paper 3 source you will ever be given. Before you can use it in an answer, you need to be clear on three things: what culture actually is, how you picked yours up without noticing, and why it makes research so easy to get wrong.
📘 What you need to know
Culture is the set of shared rules, norms, values and customs that a group passes on to its members.
Culture is a two-way street: people shape the culture they live in, and it shapes them right back.
Deep culture is the beliefs and values you cannot see. Surface culture is the behaviour you can.
Enculturation is how you soak up your own culture — mostly without realising it is happening.
An etic approach looks for what is the same everywhere. An emic approach studies a culture from the inside.
An imposed etic is measuring one culture with another culture’s ruler. It is the single biggest threat to validity in this topic.
Cultural relativism says behaviour only makes sense in its own context. Its opposite is ethnocentrism.
What culture actually is
Most students first think of culture as “which country you are from”. That is far too narrow. Culture is any set of shared rules and expectations that a group hands on to its members — so a country has one, but so does a religion, a school, a family, a football club and a workplace. You belong to several at once.
Definition
Culture = the shared norms, values, customs and rules of a group, passed on to its members through socialisation
Two features matter more than the definition itself, and both come up in mark schemes.
Culture is active, not passive. You are not a jug that culture gets poured into. People argue with their culture, bend it and change it, and the culture then shapes the next generation differently. This is why the process is described as bi-directional.
Culture is not fixed. New technology, migration, political change and even climate shift what a group treats as normal. A study of a culture is a snapshot, not a permanent portrait — which is a neat evaluation point when a source uses data collected decades ago.
If a source describes a culture as if it has always been that way and always will be, that is a limitation worth writing about. Cultures move.
Deep culture and surface culture
The bits of culture you can actually see — the food, the clothes, the festivals — are only the outer layer. Underneath sit the beliefs and values that make those behaviours make sense to the people doing them.
Researchers who only measure the tip end up describing behaviour without ever explaining it.
This is why deep culture is so hard to study. It feels like plain common sense to the people inside it, so nobody thinks to mention it in an interview. Surface culture is easy to count; deep culture is the part that actually explains the counting.
Enculturation: learning the culture you were born into
Enculturation is the type of socialisation that teaches you your own culture. It happens quietly. Nobody sits a five-year-old down and explains how close to stand to a stranger — you absorb it, and you only notice the rule exists when somebody breaks it.
Vertical transmission is the slowest to change, which is why some cultural habits outlast the reason they existed.
Enculturation is adaptive. It saves every generation from working out from scratch how to eat, greet, grieve and get along, and it keeps traditions alive. Teenagers often push back against parts of it, but most of what you absorbed early stays put, because you never consciously chose it in the first place.
Do not mix up enculturation and acculturation. Enculturation is learning your first culture as you grow up. Acculturation is what happens when you move and have to adjust to a second one. Examiners like the distinction, and plenty of students lose easy marks by using the wrong word.
Why culture makes research so hard
Early psychology was built almost entirely in Western, individualistic countries — the USA, the UK and Western Europe. The findings were then written up as if they described all humans. That is an etic approach: assume the behaviour is universal and go looking for the general law.
The trouble starts when a researcher takes a tool built in one culture and drops it, unchanged, onto another. That is an imposed etic, and it usually produces confident numbers that mean nothing.
The one to memorise
Imposed etic = using one culture’s measuring stick to judge a completely different culture
Etic approach
Emic approach
Decides what to study before arriving
Decides the focus once the research is under way
Applies the findings everywhere
Applies the findings locally
Uses measures brought in from outside
Builds measures out of local knowledge
Starts collecting data on day one
Starts collecting data once the culture is familiar
Highlights what humans share
Highlights how groups differ
Neither approach is simply “the good one”. Etic research is how we find genuine human universals, and an emic study of a single village cannot be generalised anywhere. The problem is only when an etic tool is used without checking whether it travels — that slides into ethnocentrism, judging another group by your own standards, and it wrecks external validity.
The fix is cultural relativism: work out what a behaviour means to the people doing it before you label it. Practically, that means asking local people what to measure, hiring researchers from the community, and using reflexivity — writing down your own assumptions so a reader can see where your judgement might have leaned.
🧩 Spotting cultural bias in a Paper 3 source
Who ran it? Are the researchers from the culture being studied, or visiting it?
What tool did they use? A questionnaire written elsewhere is a warning sign.
Was it translated? Ask whether the key words even exist in the other language.
Who was sampled? Students in a capital city are not “the culture”.
How were results explained? Look for a Western norm being treated as the standard.
Worked examples
WORKED EXAMPLE
Practice source: a research team based in London travels to a rural farming community abroad to study how children show respect to adults. They use a written questionnaire designed and piloted in UK schools. Explain one limitation of this method. [3 marks]
Name the limitation
The team has used an imposed etic.
the tool carries the researchers’ own ideas about what respect looks likeExplain what goes wrong
Items written for UK children may measure behaviours that are not how respect is shown in this community, and a written format assumes everyone reads comfortably.
Link it back to the data
So the scores may be measuring the wrong behaviour altogether.
The findings would lack validity3 marks = one clear limitation, explained, then linked. Do not list three.
WORKED EXAMPLE
Using the same practice source: discuss how the researchers could improve the credibility of their findings. [6 marks]
Move towards an emic design
Build the questions with people from the community, and use interviews or oral storytelling instead of a written form.
Add triangulation
Collect the same information a second way, and bring in a second researcher to analyse it independently.
Use member checking
Take the conclusions back to participants and ask whether that is really what they meant.
Be open about yourself
Reflexivity: state the team’s own cultural assumptions in the write-up so readers can judge them.
Credibility rises when local meaning drives the method“Discuss” wants a balanced review — add that emic work costs more time and money.
💡 Exam tip
Paper 3 does not test culture content directly. You apply it to whatever source you are handed, so learn the ideas as tools, not as facts to recite.
Every time you write “culture”, ask yourself whether you could name the mechanism instead — imposed etic, ethnocentrism, enculturation. Precise terms score.
For 3-mark questions give one point properly. For 6-mark questions give two or three points with evidence from the source.
Always say what the limitation does to the data (validity, reliability, generalisability). A limitation with no consequence is half an answer.
Quote the source. Examiners want to see you have actually read it, not recycled a memorised paragraph.
Keep one flexible example ready — a translated questionnaire, a Western-built diagnostic manual — that you can bend to almost any context.
⚠ Common mix-up
Culture is not the same as nationality. One country holds many cultures, and one culture can cross several countries.
Etic is not automatically bad. It is only a problem when it is imposed without checking that the measure travels.
Enculturation vs acculturation. First culture growing up vs adjusting to a new one after moving.
Cultural relativism is not “anything goes”. It means understand behaviour in context before judging it, not abandon judgement entirely.
Individualism and collectivism are dimensions, not boxes. Describing a whole country as “collectivist” is a generalisation, and saying so earns credit.
Reflexivity is about the researcher, not the participant. It means examining your own bias.
