Abstract

Fake news is a concept which recently appeared in the political speech. In this paper, we try to mathematize what it could be. We achieve this through trying to catch the notion of what information, in a human context, is. This brings us to a model which seems to work pretty well. As a consequence of this approach, we draw the conclusion that fake news broadcasting does not imply lying. We also take into account the cultural context and prove that some true information, in a given cultural context, can be felt as fake news. Finally, we also tackle permanent information channels and discuss their possibility to manipulate the information while we tackle in some way the contrary through looking at fake news in the context of historical research.
