[Kinetic exchange models of opinion formation: Some realistic applications]

How people form opinions on public issues has been a subject of intense research in recent 
times. Several agent-based models have been proposed to understand this process, involving 
different types of interactions between agents. In the kinetic exchange models of opinion 
formation, individuals' opinions evolve following an "exchange" of their opinions. We 
present a brief overview of such models before focusing on the so-called BChS model. This 
model can be applied to several realistic social phenomena and, in particular, can explain 
certain features of the US presidential election results and Brexit.
