The document discusses the concepts of cultural lag, cultural inertia, and cultural diffusion. Cultural lag refers to an imbalance in a society's culture due to different rates of change in material and non-material aspects. Material culture (e.g. technology) tends to change rapidly while non-material culture (e.g. traditions) resists change. Cultural inertia is the resistance to cultural changes and clinging to outdated traditions. Cultural diffusion is the spread of cultural ideas, beliefs, and practices to areas beyond their origin through contact between societies. Education can help address cultural lag by bridging changes in material and non-material culture.
