the influence that people have on each other through the exchange of information and knowledge in order to reduce uncertainty and make informed decisions in uncertain situations. In this type of influence, people tend to rely on the observations and behavior of others as a reliable source of information in an ambiguous or complex situation, assuming that others have experience or knowledge that can help make the right decision. From a psychological point of view, informational social influence is based on the human need to seek truth and understand the world around us. People in situations of uncertainty strive for an accurate interpretation of phenomena or events, often using the behavior of others as an indicator of correct or acceptable behavior. This type of influence promotes social learning, the adoption of group norms, and the reduction of risks associated with uninformed individual actions. From a sociological point of view, informational social influence plays a role in shaping collective attitudes, promoting shared values, and disseminating knowledge among people within a community or group. It also helps to coordinate group behavior, improve cooperation, and make better decisions in new or unfamiliar situations. Such influence often manifests itself in scientific, professional or social contexts, where a thorough assessment of facts and information is required before making a decision.
