Definition
Cross-cultural research limitations include translation problems, WEIRD-sample bias, imposed etics, and the difficulty of comparing constructs that may not exist identically across cultures.
Why it matters
Much of what appears in psychology textbooks as universal is based on Western, Educated, Industrialized, Rich, Democratic (WEIRD) samples.
The Science
Henrich, Heine, and Norenzayan’s "WEIRD" critique showed that ~96% of psychology research subjects came from ~12% of the world’s population. Generalization requires care.
The NSI Perspective
NSI holds this critique as basic scientific literacy.
Clinical Implications
Interventions developed in one cultural context should be adapted, not simply exported.
Practical Application
Not everything you read as "human nature" is actually human nature. It is often Western nature.
