A weakness of cultural bias?

-Cultural difference becoming increasingly more blurred in moderntimes -Pscyholgoists have often referenced the individualistic-collectivst culture divide, with individualistic cultures favouring independence and collectivist cultures more rooted in interdependence -However 14/15 studies into cultural differences between Japan and USA in a meta-analysis by Takano and Osaka found no evidence of the individualistic-collectivist data -Now with international travel and emigration and multi-culturalism is becoming increasingly more commn, classical view too simplistic
