How do social norms impact collective behavior during large-scale social movements?

Social norms are the unwritten rules that guide how people behave in a group. During large-scale social movements, these norms can strongly influence how individuals act together. For example, if many people in a community believe in the importance of equality, they may feel motivated to join protests for civil rights, reinforcing each other's commitment. This shared belief creates a sense of unity and purpose, making it easier for individuals to take collective action. On a larger scale, when social norms shift, like when more people start to support climate action, it can lead to widespread participation in movements aiming for change.
