Mass persuasion refers to the techniques used to influence large groups of people, often through media and communication channels. It involves strategies that appeal to emotions, beliefs, and values, aiming to change attitudes or behaviors. Common methods include advertising, public relations, and political campaigns, which leverage psychological principles to reach and engage audiences. This concept is closely related to social psychology, which studies how individuals are affected by group dynamics. Mass persuasion can be seen in various contexts, such as marketing, where brands aim to create a strong connection with consumers, or in politics, where leaders seek to rally support for their policies.
