Cultural lag
The difference between material culture and non-material culture is known as cultural lag. The term cultural lag refers to the notion that culture takes time to catch up with technological innovations, and the resulting social problems that are caused by this lag. In other words, cultural lag occurs whenever there is an unequal rate of change between different parts of culture causing a gap between material and non-material culture. Subsequently, cultural lag does not only apply to this idea only, but also relates to theory and explanation. It helps by identifying and explaining social problems to predict future problems in society.
