Uncertainty reduction theory

The uncertainty reduction theory (URT), also known as initial interaction theory, developed in 1975 by Charles Berger and Richard Calabrese, is a communication theory from the post-positivist tradition.

It is one of the few communication theories that specifically looks into the initial interaction between people prior to the actual communication process. Uncertainty reduction theory originators' main goal when constructing it was to explain how communication is used to reduce uncertainty between strangers during a first interaction. Berger explains uncertainty reduction theory as an "increased knowledge of what kind of person another is, which provides an improved forecast of how a future interaction will turn out". Uncertainty reduction theory claims that everyone activates two processes in order to reduce uncertainty. The first being a proactive process, which focuses on what someone might do. The second being a retroactive process, which focuses on how people understand what another does or says. This theory's main claim is that people must receive information about another party in order to reduce their uncertainty and, that people want to do so. While uncertainty reduction theory claims that communication will lead to reduced uncertainty, it is important to note that this is not always the case. Dr. Dale E. Brashers of the University of Illinois argues that in some scenarios, more communication may lead to greater uncertainty.

Berger and Calabrese explain the connection between their central concept of uncertainty and seven key variables of relationship development with a series of axioms and deduce a series of theorems accordingly. Within the theory two types of uncertainty are identified: cognitive uncertainty and behavioral uncertainty. There are three types of strategies which people may use to seek information about someone: passive, active, and interactive. Furthermore, the initial interaction of strangers can be broken down into individual stages—the entry stage, the personal stage, and the exit stage. According to the theory, people find uncertainty in interpersonal relationships unpleasant and are motivated to reduce it through interpersonal communication.
