“…A modified version of the DeGroot model, the Friedkin-Johnsen model [28], takes into account susceptibility to persuasion and the degree of individuals' stubbornness. Also, an alternative polar model [29,30] suggests that the susceptibility to persuasion of each individual is based on his/her current opinion. In addition to cooperative relationships, there may also be antagonistic relationships among individuals in a balanced structure, leading to a bipartite consensus in limit [13,14], which could explain the shaping of a divided population.…”

Models of opinion dynamics play a major role in various disciplines, including economics, political science, psychology, and social science, as they provide a framework for analysis and intervention. In spite of the numerous mathematical models of social learning proposed in the literature, only a few models have focused on or allow for the possibility of popular extreme beliefs' formation in a population. This paper closes this gap by introducing the Partisan Confidence (PC) model inspired by the foundations of the well-established socio-psychological theory of groupthink. The model hints at the existence of a tipping point, passing which the opinions of the individuals within a so-called "social bubble" are exaggerated towards an extreme position, no matter how the general population is united or divided. The results are also justified through numerical experiments, which provide new insights into the evolution of opinions and the groupthink phenomenon.
