The post-truth phenomenon rampant in modern society exacerbates misinformation and disinformation by turning impliedly and increasingly to cognitive bias of information seekers with no perceptible allusion to its impacts on their reasoning systems. The legitimate realm of freedom of information as established by international law and specifically shaped and implemented by national law has encountered the post-truth challenge on whose trajectory the fundamental right to access information remains inevitably vulnerable to significant derogation. The discourse on the post-truth challenge gives particular salience to a fact that it can either direct the press to erroneously and aberrantly perform its essential functions as an information provider or disseminator or lead the press to malfunction, frustrate or undermine, to a greater or lesser degree, its functional leverage for political purposes to the detriment of people’s rights to know. The recent international cases represent the post-truth evil taking on the threats to journalism and political persecution of journalists. With this in mind, the paper first articulates the contours of the post-truth challenge which impinges on or distorts the positive and vital role of the press as a watchdog safeguarding and promoting freedom of information and egregiously decries or stigmatizes the press as orienting itself astray. In turn, the paper argues that the insidious but wide-ranging post-truth effects implicates cognitive bias as a main cause of a significant impediment to democratization of information. The paper further provides the trenchant suggestion for prospective initiatives to rectify a growing cognitive bias peril and resuscitate a genuine degree of democratization of information is vigorous recourse to behavioral and structural remedies as effective corrective measures to gratify the demands of the digital times.
