Which of the following Cialdini's principles relates to how people look to others when unsure?

The principle of Social Proof is grounded in the idea that individuals often look to the actions and behaviors of others when they are uncertain about how to behave in a given situation. This psychological phenomenon stems from the belief that if many people are acting in a certain way, that action must be the correct one. Social proof serves as a heuristic that helps individuals navigate ambiguity and make decisions based on the perceived collective judgment of others.

For instance, in scenarios where people are unsure about the appropriateness of a behavior, such as when entering a new social setting or making a decision about product purchases, they may observe how others are responding and use that information to guide their own choices. This helps explain phenomena like the popularity of certain products based on positive reviews or recommendations.

When considering the other principles, Authority focuses on the influence of recognized experts and figures, Unity pertains to shared identities and connections among people, and Consistency is concerned with the idea that individuals strive to be consistent in their commitments and behaviors. While these principles have their unique contexts and applications, Social Proof specifically encapsulates the tendency to reference others in moments of uncertainty, making it the most accurate choice in this case.
