The Dynamic Social Impact Theory I think this theory is at work here
The Dynamic Social Impact Theory was developed by Latané and his colleagues in 1996. This theory is considered an extension of the Social Impact Theory as it uses its basic principles, mainly that social influence is determined by the strength, immediacy, and number of sources present, to describe how majority and minority group members influence one another. As its name suggests, the Dynamic Social Impact Theory proposes that groups are complex systems that are constantly changing and are never static. Groups that are spatially distributed and interact repeatedly organize and reorganize themselves in four basic patterns: consolidation, clustering, correlation, and continuing diversity. These patterns allow for group dynamics to operate and ideas to be diffused throughout the group.[4]
1. Consolidation – as individuals interact with each other, over time, their actions, attitudes, and opinions become uniform. In this manner, opinions held by the majority of the group spread to the minority, which then decreases in size.
2. Clustering – individuals tend to interact with clusters of group members with similar opinions. Clusters are common when group members communicate more frequently with members in close proximity, and less frequently with members who are more distant. Minority group members are often shielded from majority influence due to clustering. Therefore, subgroups can emerge which may possess similar ideas to one another, but hold different beliefs than the majority population.
3. Correlation – over time, individual group members` opinions on a variety of issues converge and correlate with each other; this is true even of issues that are not discussed by the group.
4. Continuing Diversity – a degree of diversity can exist within a group if minority group members cluster together or minority members who communicate with majority members resist majority influence. However, if the majority is large or minority members are physically isolated from one another, this diversity drops.
