Dynamic social impact theory

Dynamic Social Impact Theory (DSIT) is a comprehensive theory in social psychology that explains how individuals influence each other and how these interactions, over time, lead to the emergence of larger-scale social phenomena like culture, group norms, and social structures. Developed by Bibb Latané, DSIT is an extension of his earlier Social Impact Theory.

Core Idea and Evolution from Social Impact Theory.

The original Social Impact Theory (SIT) proposed that the amount of influence a person experiences from others is a function of three factors:

 Strength (S): The perceived power, authority, or importance of the source(s) of influence (e.g., expertise, status, attractiveness).

 Immediacy (I): The proximity or closeness of the source(s) to the target, both physically and psychologically/socially.

Number (N): The quantity of sources exerting the influence.

The formula for social impact was generally expressed as 

Impact = f(S x I x N).

While SIT predicted how sources could influence a target, a key criticism was that it often treated targets as passive recipients of influence and didn't fully account for the reciprocal nature of social interaction – how targets can also influence sources, and how these interactions evolve over time.

Dynamic Social Impact Theory (DSIT) addresses this by viewing society as a self-organizing complex system of interacting individuals. It focuses on the continuous, iterative process of influence, where individuals are both sources and targets, and how these dynamic interactions lead to four key group-level phenomena.

 1) Clustering: People tend to influence those physically or socially close to them, leading to the formation of localized groups or "clusters" with similar attitudes, beliefs, or behaviors. Think of how accents or local slang develop in specific regions. Clustering may be preceded by curiosity, hatered, fun or even ignorance, thereby bringing people together.

2) Correlation: As people within a cluster influence each other, different attitudes or behaviors within that cluster can become associated or correlated. For example, if a group of friends shares a similar political view, they might also develop similar preferences for certain media or lifestyle choices. Some may choose to break away this creating a flux in the cluster.

3) Consolidation: Over time, majority opinions or behaviors within a group tend to become stronger and more widespread, while minority views may diminish. This is a process of homogenization within a cluster. It brings decrease in the energy within the flux.

4) Continuing Diversity: Despite consolidation, DSIT also acknowledges that complete uniformity is rarely achieved. New ideas or minority opinions can emerge, especially in less dense or less immediate social networks, leading to a "continuing diversity" across the larger social system. Intra group fued and dispersion would be the negative change due formation of subculture within a social movement. More aggressive the nature of member, faster is the dispersion from within.

Implications of DSIT:

Bottom-up Emergence of Culture: DSIT suggests that culture and social structure emerge from the ground up, through everyday interactions between individuals. It's not necessarily imposed from the top down.

Reciprocal Influence: Individuals are constantly influencing and being influenced, creating a dynamic feedback loop.

Spatial and Social Proximity: Influence is often stronger among those who are closer to each other in physical or social space. At the same time proximity also is the root of subversion , a powerful tool used to disrupt social cohesion.

Non-linear Change: Small individual-level changes can, over time, lead to significant and sometimes unpredictable large-scale social transformations. Similarly some very useful and important change may be lost forever. The choice of the common people to discard very complex language and it creation like sanskrit may be an example of the adverse effect of this non- linearity.

Applications-

DSIT has been used to explain a wide range of social phenomena, including:

   1.The spread of rumors and innovations.

   2.The formation of subcultures and understanding groupism.

   3.The evolution of attitudes and beliefs within communities.

   4.The impact of online communication on social influence.

Dynamic Social Impact Theory provides a framework for understanding how seemingly simple principles of individual social influence can give rise to complex and evolving patterns of social organization and culture.
