The original theory proposed four dimensions along which cultural values could be analyzed: individualism-collectivism; uncertainty avoidance; power distance (strength of social hierarchy) and masculinity-femininity (task orientation versus person-orientation). Independent research in Hong Kong led Hofstede to add a fifth dimension, long-term orientation, to cover aspects of values not discussed in the original paradigm. In the 2010 edition of Cultures and Organizations: Software of the Mind [1] Hofstede added a sixth dimension, indulgence versus self-restraint, as a result of co-author Michael Minkov's analysis of data from the World Values Survey. Further research has refined some of the original dimensions, and introduced the difference between country-level and individual-level data in analysis.
Hofstede's work established a major research tradition in cross-cultural psychology and has also been drawn upon by researchers and consultants in many fields relating to international business and communication. It continues to be a major resource in cross-cultural fields. It has inspired a number of other major cross-cultural studies of values, as well as research on other aspects of culture, such as social beliefs.
