This document discusses how cultural factors influence social change. It provides examples of how values, attitudes, ideologies, and ideas from important figures can impact society. Cultural lag, as described by W.F. Ogburn, explains that non-material aspects of culture like beliefs and attitudes are slower to change than material aspects like technology. Cultural factors are a key source of social change as values and ideas themselves evolve over time. Great thinkers and leaders have introduced revolutionary changes in areas like religion and politics. A society's openness to new ideas and scientific inquiry can encourage or hinder social change.
