Often, research assumes that findings from western research can be applied universally, but this is not the case
For example, Asch's study into conformity found different rates of conformity in other parts of the world due to cultural differences in norms surrounding social behaviour in groups
When using Ainsworth's Strange situation tool, German mothers were seen to be cold and rejecting due to the high frequency of avoidant attachment types, but this was because German culture favours independence in their children
Culturally biased research can have significant real world effects by validating damaging stereotypes, such as the US Army IQ test before WWII that showed African-Americans were at the bottom of the scale
Recognise when it occurs, such as the finding that 66% of studies in European textbooks on social psychology were American, 32% European, and only 2% from the rest of the world
Conduct cross-cultural research to counter 'scientific racism' and promote greater sensitivity to individual difference
When carrying out research, psychologists must ensure that variables are operationalised appropriately, as the variables being investigated may not mean the same thing in all cultures
In the past, research has made the distinction between individualist and collectivist cultures, but in the age of global communication a simplistic view no longer applies
Reducing the complexity of cultural differences to two categories does not seem to make it more valid for considering this when developing an appropriate methodology, emphasising the importance of culturally relative research
