Cultural Change: Innovation and Diffusion

Cultural change is driven by internal innovations and the diffusion of ideas and practices across societies. Understanding these processes helps explain how cultures evolve and adapt over time.

Core Principles

• Culture is dynamic, not static; it constantly changes.
• Innovation is the creation of new ideas or improvements within a social group.
• Diffusion is the spread of ideas, innovations, or cultural traits from one group to another.
• Cultural change can be influenced by both internal factors (innovation) and external factors (diffusion).
• The adoption of innovations follows predictable patterns, often involving different adopter categories.
• Different types of diffusion (relocation, expansion) have distinct mechanisms and impacts.

Action Steps

• Identify the source of a cultural change: was it an internal innovation or external diffusion?
• Determine the type of diffusion: relocation (movement of people) or expansion (spread through contact)?
• If expansion diffusion, classify it further: contagious (wave-like) or hierarchical (from centers of power/influence)?
• Analyze the adoption curve: who are the innovators, early adopters, majority, and laggards?
• Consider factors influencing diffusion: cultural compatibility, social/economic structure, resistance, and connectivity.
• Recognize stimulus diffusion where the underlying principle spreads, not the specific trait.

Key Terms

• Innovation: The creation of new ideas, methods, or devices within a social group.
• Diffusion: The process by which an idea or innovation is transmitted from one individual or group to others across space.
• Relocation Diffusion: The spread of a cultural trait through the movement of people, carrying their culture with them.
• Expansion Diffusion: The spread of a cultural trait from its hearth to other regions through direct contact or influence.
• Contagious Diffusion: A type of expansion diffusion where ideas spread rapidly and widely throughout a population, like a disease.
• Hierarchical Diffusion: A type of expansion diffusion that spreads from large, influential centers (like cities) to smaller ones, or from top to bottom in a social hierarchy.
• Stimulus Diffusion: The spread of an underlying principle or idea, even if the specific characteristics or traits do not spread due to cultural barriers.
• Cultural Lag: The period of maladjustment when the material culture changes faster than the non-material culture.
• Adopter Categories: Groups of people based on their willingness to adopt an innovation (Innovators, Early Adopters, Early Majority, Late Majority, Laggards).

Timeline

• 1962: Early spread of Wal-Mart stores (example of reverse hierarchical diffusion).
• 1979: Continued expansion of Wal-Mart stores.
• 2018: TikTok first tried by innovators.
• 2019: Corona Virus Disease (COVID-19) pandemic (example of contagious diffusion).
• 2000: Widespread adoption of Wal-Mart stores across the US.
