Furthermore, Asch's research into variables affecting conformity can be criticised for culture bias as it was conducted in America (western culture) and consisted of an all American participant sample. This makes it difficult to generalise the findings to a non-western culture, such as China where social groups are more important than the individual so they may be more likely to conform and agree to be liked by the group, instead of the effect of variables. Therefore weakening the external validity of Asch's research into variables affecting conformity.
