Henrich et al - 68% of research pps from the US and 96% from industrialised nations
80% are undergraduates studying psychology
WEIRD - pps are most likely to be westernised, educated, industrialised, rich and democratic
This is seen as the 'norm' and generalises anything else as 'abnormal'
Ethnocentrism
Form of cultural bias and is the belief in the superiority of one's own cultural group
Suggests people from US and Europe have presented an ethnocentric view of human behaviour
Ainsworth's Strange Situation - only reflected norms and values of western culture and assumed secure attachment was the norm everywhere
Japanese infants more likely to be insecurely attached (Takahashi)
Cultural relativism
Berry has drawn a distinction between etic and emic approaches in the study of human behaviour
Etic - behaviour outside of a given culture to describe those behaviours as universal and can be generalised everywhere
Emic - functions from inside a culture and identifies behaviours that are specific to that culture
Ainsworth's research - imposed etic as they only conducted a study in US and UK and generalised attachment type everywhere
AO3 - Amplifies and validates stereotypes
US army used an IQ test before WW1 that was culturally biased towards the dominant white majority eg. assuming everyone would know US presidents
Recruits from south-eastern Europe and African Americans were at the bottom of the IQ scale subjecting them to negative attitudes from white Americans
Form of ethnocentrism and highlights that culturally biased research reinforces prejudice and discrimination
AO3 - Findings and conclusions unrepresentative of real life
Ainsworth's study of attachment, Adorno's f-scale study and Milgram's obedience study, all US pps were used from middle class backgrounds and conducted in only individualistic cultures
Henrich et al. WEIRD acronym
Imposed etic approach allows findings to not be generalised and lacks universality
Lack of understanding surrounding collectivist cultures meaning there may be implications around certain topics
AO3 - Counterpoint of replication to reduce cultural bias
Van Ijzendoorn and Kroonenberg successfully replicated Ainsworth's Strange Situation across a range of different cultures, including collectivist ones
Discovered secure attachment was not the norm everywhere and in places such as Japan, insecure attachment was more common (Takahashi)
Milgram's obedience study replicated as a French gameshow which validated original findings as pps behaved same
Allows for more varied research and reduces ethnocentrism
