Definitions of culture and cultural bias

Culture consists of the customs, social roles, behavioural norms, and moral values shared among a group of people.

Cultural bias in psychology occurs when research primarily reflects the culture of the researchers, which can result in inaccurate generalisations to other groups.

Historical ways psychologists ignored cultural differences

Psychologists in the past frequently disregarded cultural diversity by:

• Assuming that individuals from Western cultures were fundamentally similar to those from other cultures.
• Extending findings from one culture to apply universally across all cultures.
• Viewing non-Western cultures as more primitive and less deserving of investigation.
• Facing constraints in time and resources that limited cross-cultural studies.

Approaches to research that lead to cultural bias

Different research methods can introduce cultural bias, particularly when attempting to apply findings across diverse groups.

Etic and emic research approaches

Berry (1969) outlined two primary research strategies that contribute to cultural bias.

Research approaches:

• Etic research - Involves studying behaviour from the perspective of one culture and applying it to others to identify universal principles.
• Emic research - Focuses on examining a single culture from within to understand its unique aspects.

Etic approaches risk creating an imposed etic, where concepts from one culture are inappropriately forced onto another, leading to biased interpretations.

Emic approaches help explore variations between groups and avoid imposed etic bias, but they can overemphasise differences between cultures while ignoring variations within them.

Universality in psychological concepts

Universality refers to psychological traits or behaviours that appear consistent across all cultures. All humans share similar physiology, and certain behaviours, such as language use, attachment formation, and aggression, occur universally.

However, using samples from a single population makes it challenging to generalise findings to all cultures, often resulting in bias through imposed etics.

Sub-culture bias in research

Sub-culture bias arises when studies concentrate on one subgroup within a broader population, overlooking others, and then generalise results inappropriately.

For example, research that only examines monogamous relationships while ignoring polyamorous ones may wrongly apply findings to all relationship types.

Ethnocentrism and its effects

Ethnocentrism involves treating one's own culture as the standard for judging others. Research affected by ethnocentrism centres on the researchers' culture, often Western societies, leading to biased perspectives. Most psychological studies have historically focused on Western participants, making them inherently ethnocentric.

Examples of cultural bias in psychological studies

Several classic studies demonstrate cultural bias through their methods and generalisations.

Asch's conformity research

• Asch (1951) investigated conformity by presenting participants with line judgement tasks and observing how they yielded to group pressure.
• The study exhibited ethnocentrism and etic bias by sampling only Americans and assuming results applied universally, without considering cultural variations in conformity.

Milgram's obedience study

• Milgram (1963) explored obedience by instructing participants to administer electric shocks to a learner for wrong answers.
• While identifying influences on obedience, the study created an imposed etic by not accounting for cultural differences in authority responses across countries.

Implications and challenges of cultural bias

Culturally biased research can lead to flawed theories with real-world consequences, particularly in areas like mental health.

Social implications in mental health

Biased studies influence psychological practices, such as diagnosing and treating mental illnesses.

Research findings on schizophrenia diagnoses:

• Cochrane and Sashidharan (1995) examined schizophrenia diagnoses in the UK and found African-Caribbean individuals were up to seven times more likely to receive a schizophrenia diagnosis than white patients.
• Littlewood and Lipsedge (1989) investigated medication practices and found African-Caribbean patients often received higher doses of medication than white patients with similar symptoms.

Challenges in cross-cultural research

Conducting research across cultures presents several obstacles:

• Interpreting participants' responses is difficult due to varying beliefs and customs.
• Researchers may misinterpret behaviours based on their own cultural norms.
• Perfect replication of studies is impossible, as procedures carry different meanings in different cultures.

Smith and Bond (1988) argued that exact cross-cultural replications cannot occur because study procedures hold unique significance in each culture.

Ways to reduce cultural bias

Reducing cultural bias requires deliberate strategies to promote more inclusive and accurate research.

Strategies for minimising bias

• Embracing cultural relativism - Acknowledging that no universal standards for behaviour exist, and norms vary by culture.
• Using representative samples - Including diverse subgroups to ensure findings reflect broader populations.
• Conducting contextually relevant research - Performing studies in appropriate settings with local researchers familiar with the culture to enhance understanding and accuracy.
