History and Orientation
Uncertainty reduction theory (URT) was initially presented as a series of axioms (universal truths which do not require proof and theorems (propositions assumed to be true) which describe the relationships between uncertainty and several communication factors. URT was developed to describe the interrelationships between seven important factors in any dyadic exchange: verbal communication, nonverbal expressiveness, information-seeking behavior, intimacy, reciprocity, similarity, and liking. This theoretical perspective was originated by C.R. Berger and Calabrese in 1975; they drew on the work of Heider (1952).
Core Assumptions and Statements
Core: Uncertainty is unpleasant and therefore motivational; people communicate to reduce it. Uncertainty reduction follows a pattern of developmental stages (entry, personal, exit). During the entry stage information about another’s sex, age, economic or social status, and other demographic information is obtained. Much of the interaction in this entry phase is controlled by communication rules and norms. When communicators begin to share attitudes, beliefs, values, and more personal data, the personal stage begins. During this phase, the communicators feel less constrained by rules and norms and tend to communicate more freely with each other. The third stage is the exit phase. During this phase, the communicators decide on future interaction plans. They may discuss or negotiate ways to allow the relationship to grow and continue. However, any particular conversation may be terminated and the end of the entry phase. This pattern is especially likely to occur during initial interaction, when people first meet or when new topics are introduced later in a relationship.
Besides the stages in uncertainty reduction patterns makes Berger a distinction between three basic ways people seek information about another person: (1) Passive strategies - a person is being observed, either in situations where the other person is likely to be self-monitoring* as in a classroom, or where the other person is likely to act more naturally as in the stands at a football game. (2) Active strategies - we ask others about the person we're interested in or try to set up a situation where we can observe that person (e.g., taking the same class, sitting a table away at dinner). Once the situation is set up we sometime observe (a passive strategy) or talk with the person (an interactive strategy). (3) Interactive strategies - we communicate directly with the person.
People seek to increase their ability to predict their partner’s and their own behavior in situations. One other factor which reduces uncertainty between communicators is the degree of similarity individuals perceive in each other (in background, attitudes and appearance).
Statements: the axioms in URT follow the “If… then…” statements typical of the law-governed approach. For example: “If uncertainty levels are high, the amount of verbal communication between strangers will decrease.”
*Self-monitoring is a behavior where we watch and strategically manipulate how we present ourselves to others.

Scope and Application
Organizational communication, society. Uncertainty reduction theory also applies at the organizational and societal levels (risk society).
