A weakness is that there are cultural differneces in the Order of needs.FE a psychologist carried a study in china and found that belongingness needs wher seen as more fundamental than psychological needs and that self-actualisation was defined more in terms of contribution to communities rather than individual development.TMB some people, needs may appear in a different order or may ne absent altogether, particularly if from collectivist culture.This is borne out by cross-cultural evidence.Therefore approach may be seen as culturally bias.
