Evaluation: Cultural bias (limitation)
The approach may be culturally-biased.
Many ideas that are central to humanistic psychology, such as individual freedom, autonomy and personal growth, are more associated with countries that have more individualist tendencies (ie. USA).
Countries with collectivist tendencies emphasise more the needs of the group and interdependence. In such countries, the ideals of humanistic psychology may not be as important as in others.
It's possible that the approach doesn't apply universally and is a product of the cultural context within which it was developed.
