The concept of uncertainty reduction theory (URT) is very simple to understand, when strangers meet for the first time; the main goal is to reduce uncertainty between them, during the meeting. It's basically about how we go about the basic process by which we get to know other people. According to communication professors Charles Berger and Richard J. Calabrese “Reducing uncertainty is particularly important in developing relationships, so it is typical to find more uncertainty-reducing behaviors among people when they expect or want to develop a relationship than among people who expect or know they can do it. will not develop a relationship” (Berger, Calabrese, 1975). URT applies to certain assumptions about interpersonal communications, such as the idea that people experience uncertainty during new interpersonal encounters or that when people first encounter their primary concern they try to reduce this uncertainty and increase the level of predictability (Wikibooks, 2013). The URT can be divided into three phases, the entry phase, the second phase and the final phase. Several axioms link relationship development and uncertainty. Two of these axioms would be that there is an inverse relationship between intimacy and uncertainty and there is a positive relationship between reciprocity and uncertainty, each feeding off the other in the communication process. Another important axiom is self-explanatory, the idea that people who are more likely to be able to reduce uncertainty than those who have many differences (Wikibooks, 2013). Developed in 1975 by Berger and Calabrese, various clinical axioms and institutional studies of URT have been conducted for corporate, academic, and government purposes. One of these studies is recent and tested a model... middle of paper... interesting but unclear, the researcher's attention was focused exclusively on a communicative style of analysis, which left out the physiological aspect in study. The final results made it clear that types of betrayal played an important role in re-establishing URT and relationship survival. Works Cited Antheunis, Marjolijn L., Patti M.
