Abstract
This essay argues that the success of «post-truth» is partially connected to the characteristics of the new «hybrid» communication scenario. The author maintains that the current context differs substantially from the _democracy of parties_, which has characterised a part of the 20 th century, as well as from the _democracy of the public_, a notion formulated by Bernard Manin in the mid-1990s. As a matter of fact, the diffusion of the new media has triggered the fragmentation of _the public_ into a plurality of self-referential segments and «bubbles» which are (potentially) not rooted in an intersubjective sphere of communication. Considering the impact of these transformations, the essay proposes the image of a _bubble democracy_ as an alternative to the mainstream interpretations both of the _democracy of parties _and of the _democracy of the public_ and it argues that its main features are the widespread mistrust towards institutions, audience fragmentation and polarisation.
