A perspective where the behaviours of a certain ethnicity or culture are seen as the default and normal. As such, any behaviour that deviates from the norms of that culture may be seen as abnormal
Ainsworth's studies only looked at American infants and concluded that secure attachment styles are best. From this perspective, child-rearing practices in other countries may be seen as psychologically abnormal
• Given that all humans in all cultures have very similar biology, there are likely to be many universal psychological truths, so etic research is not automatically bad. But if researchers assume their culture is the default, that's where the bias comes in. Psychological research can avoid cultural bias by being conscious of culturalrelativism.
