In his book Post-Truth (2018), Lee McIntyre demonstrates the intellectual origins of the notion of post-truth by giving examples from diverse areas such as marketing, broadcasting, and the studies of behavioural psychology in the 20th century. McIntyre claims that post-truth is solely an epistemological problem. In this essay, firstly, the similarities between the post-truth and the coherence theory of truth will be elaborated and their common problems will be briefly discussed. After this discussion, Lee McIntyre’s approach will be problematized by establishing parallelism between the personalization technologies with their unintended outcomes such as echo chambers, filter bubbles & cyber-balkanization, and Louis Althusser’s ideological apparatus of the state. Moreover, it will be suggested that since the personalization technologies transform each individual into a prosumer, the notion of post-truth is deeply related to the fields of both theoretical and practical philosophy and it is, in fact, nothing more than a neologism replacing the term, ideology.
