Uncertainty reduction theory

From Wikipedia, the free encyclopedia

Uncertainty Reduction Theory was introduced in 1975 in a paper entitled Some Exploration in Initial Interaction and Beyond: Toward a Developmental Theory of Interpersonal Communication. This theory, a collaborative effort of Charles R. Berger and Richard J. Calabrese, was proposed to predict and explain relational development (or lack thereof) between strangers.

The scope of the theory is narrowed down to rest on the premise that strangers, upon meeting, go through certain steps and checkpoints in order to reduce uncertainty about each other and form an idea of whether one likes or dislikes the other. To study this phenomenon, the interaction is viewed as going through several stages. Berger and Calabrese also introduce axioms and theorems regarding initial interaction behaviors.
