Abstract

“Post-truth” is a misleading label: there is no new concept of truth, nor is there a change in what is true. However, there is something new, and bad, happening in our dealings with truth: the lack of trust in institutions dedicated to produce knowledge. In this chapter, I try to explain why this happens. I also address the effects of this lack of trust in the election of a far-right president in Brazil. The changes in our epistemic landscape result from deep-rooted features in human culture, the conflict between epistemic values, as embodied in our cooperative efforts to produce knowledge, and coordination values, that make the identitary function of beliefs very salient. Moreover, in the unstructured information landscape of the Internet, it is very difficult to read cues for reliable sources. There is another structural factor that plays an important role, the increasing inequalities, creating an environment in which status and identitary anxieties also increase, making identitary claims very powerful. These anxieties are exploited by the far-right, against our moral and epistemic common ground. The equilibrium between the coordination game and the epistemic game is fragile. The victim is our epistemic common ground.
