Citizen engagement in the “post-truth era”

The purpose of this study is to analyze citizen engagement and to explain the underlying mechanism that makes well-intended people to act as disinformation amplifiers in the online space. The study offers new insights to be used by knowledge management for improving society’s potential to downsize the impact of disinformation that puts both knowledge system and social trust (ST) under high pressure.,The study proposes an integrative research model to explain how ST and conspiracy mentality (CM) are influencing citizen engagement in public life through different forms of action that is specific to offline or online spaces. The research model and its nine hypotheses are tested based on a survey for data collection and partial least squares method for data analysis.,The study finds that both online and offline actions are mediating the positive effect of ST on citizen engagement. Yet, CM has a high impact on online actions, and it exerts a significant indirect influence on citizen engagement in this manner.,Revealing the mediator role of online actions in the relationship between CM and civic engagement, the paper brings novel insights on disinformation spreading. The study explains how citizen engagement can sometimes be turned against social well-being because those prone to belief in conspiracies are the perfect targets of deceivers seeking for disinformation amplifiers in the online environment.
