Cultural bias occurs when psychological research, theories or conclusions are distorted by the values and assumptions of a particular culture. This Cultural bias A-Level Psychology revision page explains ethnocentrism, cultural relativism and the difficulty of making universal claims about behaviour. These ideas form part of Issues and Debates in Psychology and build on how bias can distort psychological explanations. Understanding them will help you evaluate research rather than accepting broad claims about human behaviour without checking the evidence behind them.

Define cultural bias.
Explain ethnocentrism and its possible consequences.
Explain cultural relativism.
Distinguish ethnocentrism from cultural relativism.
Apply cultural bias to unfamiliar research scenarios.
Evaluate claims that psychological theories and findings are universal.

Cultural bias A-Level Psychology revision: the core issue
Cultural bias occurs when psychological research or theory is influenced by the norms, values and assumptions of a particular culture.
Bias can arise when psychologists:
judge people from another culture using the standards of their own culture
assume that behaviour considered normal in one culture is normal everywhere
use research methods that are appropriate for one culture but not another
generalise findings from one cultural group to all people
describe cultural differences as evidence that one group is less developed or less capable
The AQA specification requires students to understand cultural bias through ethnocentrism, cultural relativism and the wider issue of universality.
Cultural bias is not simply the fact that research was conducted in one culture. A study may legitimately investigate a specific cultural group. The problem arises when its methods, interpretations or conclusions fail to recognise the limits of the cultural context.
Culture, norms and values
A culture is a group of people who share particular norms, values, beliefs and practices.
Norms are expectations about what behaviour is considered usual or acceptable within a group. These expectations may influence:
child-rearing
relationships
emotional expression
social behaviour
ideas about health and mental disorder
responses to authority
attitudes towards independence and group membership
Because cultural norms can differ, behaviour may have different meanings in different cultural settings.
This is especially important when studying behaviour judged according to cultural expectations.
Ethnocentrism
Ethnocentrism means judging other cultures using the norms, standards and values of one’s own culture.
At its most extreme, ethnocentrism includes the assumption that one’s own culture is superior to other cultures.
An ethnocentric psychologist may:
treat the behaviour of their own culture as normal
assume that other cultural practices are abnormal or deficient
design research using assumptions taken from their own culture
interpret differences as evidence of inferiority
present findings from their own culture as universally true
A complete definition must therefore contain two connected ideas:
Other cultures are judged using the standards of the researcher’s culture.
The researcher’s culture may be viewed as the normal, correct or superior standard.
Exam focus: Writing only that ethnocentrism is “cultural bias” is too vague. You must explain the judgement of other cultures and the assumption of cultural superiority.
An example of ethnocentrism
Imagine that a psychologist develops a test of healthy social development in one culture. The test rewards children for speaking independently, making decisions without adults and expressing their own opinions.
The psychologist then uses the same test in another culture where children are encouraged to consult family members, respect older relatives and make group decisions. The second group receives lower scores.
It would be ethnocentric to conclude that the children in the second culture are less socially developed without considering that:
the test reflects the expectations of the first culture
social development may be expressed differently across cultures
the second group is being judged using standards that may not fit its cultural context
The scores may therefore reveal differences in cultural expectations rather than differences in psychological development.
The adoption of a Western norm
Cultural bias can occur when psychological research treats behaviour associated with Western cultures as the standard against which everyone is judged.
A Western norm is created when:
theories are mainly developed within Western settings
participants are mainly recruited from Western populations
Western values are built into tests or procedures
findings are applied to cultures that were not represented
behaviour that differs from Western expectations is described negatively
This does not mean that research conducted in Western cultures is automatically invalid. The issue is whether psychologists recognise the limits of their samples and methods.
Research from one culture can still be useful, provided its conclusions are appropriately restricted and do not claim to describe people who were not studied.
How ethnocentrism may affect psychological research
Ethnocentrism can enter research at several stages.
Stage of research | Possible ethnocentric influence |
Forming a theory | The researcher assumes behaviour valued in their own culture is universally normal |
Choosing participants | One cultural group is studied but treated as representative of everyone |
Designing a task | The task relies on knowledge or experiences specific to one culture |
Measuring behaviour | A test defines success using one culture’s standards |
Interpreting findings | Cultural differences are interpreted as deficiencies |
Reporting conclusions | One cultural explanation is presented as universally true |
Applying findings | A theory or treatment is used with groups not represented in the original research |
The suitability of a sample is therefore important. Understanding how samples affect wider conclusions will help you recognise when a cultural generalisation is unsupported.
Problems associated with ethnocentrism
Reduced validity
A culturally inappropriate test may not measure the intended behaviour accurately.
For example, a measure designed around the norms of one culture may produce lower scores in another culture because the task is unfamiliar or culturally unsuitable. The results may then reflect the design of the test rather than a genuine psychological difference.
Limited generalisability
Findings from one cultural group cannot automatically be applied to all cultures.
A researcher may have produced an accurate explanation of the people studied but an inaccurate explanation of people from different cultural backgrounds.
The broader the claim, the more evidence is needed to support it.
Negative judgements about other cultures
Ethnocentrism may lead researchers to describe cultural differences using terms such as:
abnormal
immature
deficient
less intelligent
less emotionally developed
These descriptions may reflect the researcher’s cultural assumptions rather than an objective difference.
Stereotyping
Researchers may treat all members of another culture as if they are identical.
This ignores individual differences within cultures. People who share a cultural background do not necessarily behave in the same way, hold identical values or have the same experiences.
Prejudice and discrimination
Biased research may strengthen negative beliefs about cultural or ethnic groups.
Psychological findings can influence public attitudes, education, diagnosis and social policy. Poorly supported conclusions may therefore have consequences beyond the original investigation.
This makes cultural bias relevant to the wider consequences of psychological findings.
Cultural relativism
Cultural relativism is the view that behaviour can only be properly understood within the cultural context in which it occurs.
The meaning of a behaviour depends on the norms, values and social environment of the culture.
According to cultural relativism:
behaviour should not be judged using standards taken from another culture
a behaviour may have different meanings in different cultural settings
researchers should understand the norms surrounding the behaviour
findings should not be generalised beyond the cultural context without appropriate evidence
Cultural relativism does not simply mean that cultures are different. It means that cultural context is necessary for interpreting behaviour accurately.
An example of cultural relativism
Imagine that children in two cultures behave differently during separation from a caregiver.
An ethnocentric interpretation might judge both groups using the expectations of one culture and label one pattern as less desirable.
A culturally relative interpretation would consider:
the child-rearing practices within each culture
cultural expectations about independence and closeness
how familiar separation from a caregiver is
what the observed behaviour means within that particular cultural setting
The specification includes cultural variations in attachment and the work associated with van Ijzendoorn. This provides a useful way of applying cultural relativism because attachment behaviour may need to be interpreted in relation to differing child-rearing practices and expectations. Understanding how attachment patterns vary between cultures can therefore strengthen an Issues and Debates answer.
The 2025 mark scheme accepted attachment as an appropriate application of cultural relativism when cultural differences were linked to child-rearing norms and parenting expectations.
Ethnocentrism and cultural relativism compared
Feature | Ethnocentrism | Cultural relativism |
Main idea | Other cultures are judged using the standards of one’s own culture | Behaviour is understood within the culture in which it occurs |
View of cultural norms | One culture’s norms may be treated as normal or superior | Different norms may give behaviour different meanings |
Risk | Other cultures may be misrepresented or devalued | Broader generalisations may become difficult |
Approach to differences | Differences may be interpreted as deficiencies | Differences are interpreted in relation to cultural context |
Generalisation | Findings from one culture may be applied too widely | Findings are restricted unless evidence supports wider application |
Key question | Is one culture being used as the standard? | What does this behaviour mean within this culture? |
Do not confuse the two concepts
Ethnocentrism and cultural relativism are not two names for cultural bias.
Cultural bias is the broader distortion.
Ethnocentrism is one way that cultural bias can occur.
Cultural relativism is an approach that aims to understand behaviour in context and can help reduce inappropriate cultural judgements.
An answer that defines cultural relativism as “judging another culture using your own standards” has actually described ethnocentrism.
Universality in Psychology
Universality is the claim that a psychological theory, explanation or finding applies to all people.
Psychologists may seek universal explanations because they aim to identify general patterns of behaviour. A genuinely universal explanation should remain applicable across different cultural contexts.
Examples of universal claims might include statements such as:
all humans develop behaviour in the same way
the same psychological process operates in every culture
a theory explains behaviour regardless of cultural background
a particular treatment is suitable for everyone
A universal claim may be justified, but it must be supported by appropriate evidence.
When is a claim of universality justified?
A claim is more convincing when:
relevant cultural groups have been included in the research
similar findings have been obtained in different cultural settings
the procedure measures the same behaviour across those settings
researchers have considered different cultural meanings
conclusions accurately reflect the populations represented by the evidence
A theory should not be called universal merely because it was developed from a large sample. A large sample from one cultural group may still be culturally restricted.
Unjustified claims of universality
An unjustified claim of universality occurs when psychologists assume that findings apply to everyone without sufficient evidence.
For example:
A researcher studies 1,000 people from one country and concludes that the results reveal a universal feature of human behaviour.
The large sample may improve confidence in conclusions about the population represented by that sample. However, it does not automatically show that the finding applies to other cultures.
The issue is not only the number of participants. It is also the range of cultural contexts represented.
Cultural bias and generalisability
Generalisability concerns whether findings can be applied beyond the original sample.
A theory may have:
good generalisability within the culture studied
poor generalisability to other cultures
evidence supporting application across several cultures
insufficient evidence for a universal claim
Students should avoid making an all-or-nothing judgement. Research does not become completely useless because it was conducted in one culture. Its conclusions may simply need to be limited to the population and context represented.
Cultural relativism and universality
Cultural relativism and universality create an important tension in Psychology.
Cultural relativism emphasises | Universality emphasises |
The meaning of behaviour within a particular context | Psychological processes that apply broadly |
Differences between cultural settings | Similarities across human beings |
Cautious generalisation | The development of general explanations |
Local norms and values | Wider patterns and principles |
Context-specific interpretation | Application beyond the original sample |
Psychologists should not assume that one position is always correct.
Some psychological processes may be widely shared, while the way they are expressed or interpreted may be influenced by culture.
A balanced conclusion is therefore that:
universal claims must be tested rather than assumed
cultural differences must be understood rather than automatically judged
similarities should not be ignored when they are supported by evidence
research conclusions should match the cultural range of the data
Evaluating claims of universality
Universal explanations can be useful
If a psychological explanation is genuinely supported across different cultures, it may provide a broad understanding of human behaviour.
A well-supported universal explanation could:
identify shared psychological processes
allow findings to be applied widely
support predictions across different populations
contribute to general psychological theories
The problem is not the aim of universality. The problem is claiming universality before sufficient evidence has been collected.
One culture may be treated as representative of humanity
Many theories are developed from culturally restricted samples.
If psychologists present these findings as universally true, the theory may describe the norms of the culture studied rather than human behaviour as a whole.
This can result in:
inaccurate generalisations
inappropriate applications
culturally biased measurements
the adoption of one culture as the norm
A theory can be culturally limited without being worthless
A culturally restricted theory may still explain behaviour effectively within the setting in which it was developed.
A careful evaluation should therefore avoid claiming:
“The research is culturally biased, so it has no value.”
A more developed conclusion would be:
“The findings may explain the population studied, but further evidence would be needed before applying them to people from different cultural settings.”
Cultural relativism may improve validity
Interpreting behaviour in its cultural context can improve validity because researchers consider what the behaviour actually means to the people being studied.
This can prevent psychologists from:
labelling unfamiliar practices as abnormal
using culturally inappropriate measurements
mistaking difference for deficiency
imposing one culture’s standards on another
Extreme cultural relativism can limit general explanations
If psychologists assume that every behaviour can only be understood within one specific cultural setting, it becomes difficult to identify similarities or develop broader psychological explanations.
This may limit psychology’s ability to:
compare findings
identify shared patterns
construct general theories
make predictions beyond one setting
The most defensible position is not to reject universality, but to require evidence before accepting it.
This tension also links to the search for general laws and the study of individual experience.
Applying cultural bias to Attachment
The specification includes cultural variations in attachment, including van Ijzendoorn.
This topic can illustrate cultural bias because attachment behaviour must be interpreted carefully.
A psychologist should not assume that:
one attachment pattern is automatically the ideal in every culture
the same behaviour has an identical meaning in every setting
a procedure developed in one culture measures attachment equally well elsewhere
differences necessarily indicate poorer parenting
A culturally relative interpretation considers how child-rearing norms and expectations may influence behaviour.
In an examination, do not simply write:
“Van Ijzendoorn shows cultural bias.”
Instead, explain the link:
Research into cultural variations in attachment illustrates cultural relativism because attachment behaviours may differ according to child-rearing practices and expectations. These behaviours should therefore be interpreted within the culture in which they occur rather than judged against one universal standard.
Applying cultural bias to mental health
The definition of abnormality based on deviation from social and cultural norms also illustrates cultural relativism.
A behaviour may be considered acceptable in one cultural setting but unusual in another. This means that judging mental health only through one culture’s norms may produce a biased conclusion.
A culturally informed interpretation considers:
the norms of the person’s cultural group
the setting in which the behaviour occurs
the meaning attached to the behaviour
whether the judgement has been based on an inappropriate external standard
This does not mean that every behaviour is acceptable simply because it occurs within a culture. It means that cultural context should be considered before behaviour is classified or interpreted.
How psychologists can reduce cultural bias
Include relevant cultural groups
Researchers should include participants from the cultural groups to which they intend to apply their conclusions.
The sample should be suitable for the aim of the study and for the breadth of the claim being made.
Limit conclusions appropriately
If only one culture has been studied, psychologists should avoid presenting the findings as universal.
They should state clearly:
who was studied
where the research took place
which population the conclusions may apply to
where further evidence is needed
Consider cultural norms during research design
Researchers should examine whether their:
questions
tasks
measures
instructions
interpretations
are appropriate for the cultural groups being studied.
A direct translation of a test may not be enough if the assumptions behind the task are culturally specific.
Use researchers familiar with the culture
Researchers who understand the cultural setting may be better able to recognise:
local meanings
culturally appropriate procedures
misleading interpretations
assumptions imported from another culture
Familiarity alone does not guarantee unbiased research, but it may reduce obvious misunderstandings.
Compare findings across cultural settings
Research involving more than one cultural setting can help psychologists investigate whether a finding is:
widely shared
expressed differently across cultures
limited to a particular context
influenced by the method used
However, simply including several cultures is not enough. The procedure must still measure the intended behaviour appropriately in each setting.
Avoid treating cultures as uniform groups
Researchers should recognise individual differences within cultures.
Statements such as “people from this culture behave in this way” may create a stereotype if they ignore variation between individuals.
A three-step method for application questions
When a scenario may contain cultural bias:
Identify the concept.
State whether the scenario demonstrates ethnocentrism, cultural relativism or an unsupported universal claim.
Select evidence from the scenario.
Quote or paraphrase the relevant feature of the sample, procedure or conclusion.
Explain the link.
Show why the feature demonstrates the concept.
Applied example
A psychologist develops a questionnaire in Culture A and uses it to investigate emotional maturity in Culture B. Participants from Culture B receive lower scores, so the psychologist concludes that people from Culture A are more emotionally developed.
A developed answer might state:
This conclusion is ethnocentric because participants from Culture B have been judged using a measure based on the norms of Culture A. The psychologist has interpreted lower scores as evidence of poorer development and has therefore treated Culture A’s behaviour as the superior standard.

Hints from the Examiner Reports 💡
Examiner hint: A definition of ethnocentrism must include the idea of cultural judgement or superiority. In 2024, some students described cultural bias generally but did not explain that other cultures were being judged according to the researcher’s own culture.
Examiner hint: Do not substitute a definition of cultural bias for a definition of cultural relativism. The 2025 report identified this as a common error.
Examiner hint: Develop your definition of cultural relativism. Referring only to “different cultural norms” is unlikely to be enough. Explain that behaviour has meaning within its cultural context and that findings should not automatically be generalised beyond it.
Examiner hint: When a question asks you to use a topic, make the connection explicit. Strong responses in 2025 used cultural variations in attachment and explained how differences could reflect child-rearing norms and parenting expectations. Simply naming van Ijzendoorn would not demonstrate the link.
Examiner hint: For a limitation of ethnocentrism, state the negative consequence clearly. For example, do not write only “the findings cannot be generalised”. Explain that a culturally restricted study may not provide a valid explanation of people from cultures that were not represented.
Examiner hint: Developed limitations may address stereotyping, discrimination, the use of a Western norm or the inability to generalise beyond the culture studied.
Examiner hint: When asked for two ways of reducing cultural bias, make sure they are genuinely different. The 2020 report noted that some students repeated the same idea twice using two versions of “study different cultures”.
Examiner hint: Use the whole scenario in application questions. Identify a specific cultural assumption, task, sample or conclusion and connect it directly to the relevant concept.
Examiner hint: In an extended response, combine accurate definitions with an applied example and developed evaluation. A list of cultures or studies without explanation will not demonstrate analysis.
Common Mistakes ⚠️
Mistake: Defining ethnocentrism as “research involving one culture”
Why this is incorrect:
A study may legitimately focus on one culture. Ethnocentrism involves judging other cultures using one’s own cultural standards, often with an assumption of superiority.
How to improve:
Include both cultural judgement and the use of one culture as the normal or superior standard.
Mistake: Forgetting the idea of cultural superiority
Why this is incorrect:
Saying that cultures are compared does not fully explain ethnocentrism.
How to improve:
State that the researcher’s own cultural norms may be treated as more correct, desirable or developed.
Mistake: Defining cultural relativism as cultural bias
Why this is incorrect:
Cultural bias is a distortion. Cultural relativism is the view that behaviour must be understood within its cultural context.
How to improve:
Use the phrase “understood within the culture in which it occurs”.
Mistake: Claiming that cultural relativism means every culture is superior
Why this is incorrect:
Cultural relativism does not rank cultures. It argues that behaviour should be interpreted using the appropriate context.
How to improve:
Focus on meaning, norms and context rather than superiority.
Mistake: Assuming all findings from one culture are invalid
Why this is incorrect:
A study may provide valid information about the population investigated. The problem arises when conclusions are generalised beyond the supporting evidence.
How to improve:
Evaluate the limits of the claim rather than dismissing the entire investigation.
Mistake: Assuming a large sample proves universality
Why this is incorrect:
A large sample may still represent only one culture.
How to improve:
Consider both sample size and the cultural groups represented.
Mistake: Treating cultural groups as if all members are identical
Why this is incorrect:
There are individual differences within every culture.
How to improve:
Avoid broad stereotypes and refer to patterns or findings rather than claiming that every person behaves in the same way.
Mistake: Name-dropping a topic without applying it
Why this is incorrect:
Writing “van Ijzendoorn shows cultural relativism” does not explain the connection.
How to improve:
Explain that attachment behaviour may vary with cultural child-rearing practices and should therefore be interpreted within its cultural setting.
Mistake: Giving the same improvement twice
Why this is incorrect:
“Study two cultures” and “include participants from another culture” may express the same basic point.
How to improve:
Choose clearly different strategies, such as improving cultural representation and limiting conclusions to the population studied.
Mistake: Writing only that ethnocentrism is “bad”
Why this is incorrect:
This does not identify a psychological or scientific consequence.
How to improve:
Explain how it may reduce validity, prevent generalisation, reinforce stereotypes or contribute to discrimination.
