Emergence of the Post-truth Situation: Its Sources and Contexts [El surgimiento de la posverdad: sus orígenes y contextos]

We often encounter the term "post-truth situation" in quite different contexts. This paper compares existing approaches to the term, reviewing sources of this notion in different domains (scientific, political, economic, academic) and fundametally identifying its conceptual core. The starting point is the analysis of the recent transformation of the relationship between scientific fact and the political sphere and the change of the role of experts in relationship to society. The next section focuses on the role of digital and especially social media in the emergence of the post-truth society and some important phenomena that are constitutive for the post-truth society in the information arena. Subsequently, we identify other sources of post-truth situations in the economic sphere, which is related to globalization, and also in the field of postmodern philosophy
