Psychological Dimensions of Political Deception: A Case Study of Donald J. Trump’s Political Discourse

Abstract

Deception in political discourse is tantamount to psychology, and existing research definitely lacks a precise psychological framework analyzing how strategic lies can be extremely effective in political messaging of the highest order. The research problem includes treating deception as merely a line, as confirmed by traditional political analysis, rather than as a complex psychological process. Scholars depict a major political figure, but they lack a clear model of how specific linguistic cues manipulate the electorate's perceptions, thereby maintaining political loyalty in the wake of factual inaccuracies. The research object and data corpus include the political discourse of the 45th and 47th presidents of the United States of America, Donald J. Trump, and his public statements as a case study. The data corpus includes press conference remarks, rally transcripts, and a curated selection of public speeches from verified social media communications, obtained from major presidential debates and campaign releases. The psychological framework includes cognitive dissonance theory, terror management theory, and social identity theory, which together provide a lens on charismatic authority dynamics. This framework focuses on reinforcing psychological safety Nets for followers, depending on how speakers exploit in-group and out-group biases. The analytical methods include psychological text interpretation through qualitative discourse analysis, combined with an evaluation of defensive framing, systematic inversion of factual consensus, emotional appeals, and, most importantly, linguistic patterns. In this regard, the “Bottomless Pinocchio” project of the Washington Post, which exclusively analyzes Donald Trump's behavior, has been employed to fact-check our discourse. The key findings present in this article include a subjective truth tied to group identity rather than factual accuracy, which is the common notion employed by Trump's discourse; image reframes object defaults through this methodology. This functional deception strengthens in-group solidarity as a cohesive social tool, framing outsiders as attacks on the group itself. At the same time, anyone who tries to correct it is placed in that category. The theoretical contribution includes identity-protective deception in populist rhetoric, an advanced, unified model employed by President Trump to make his politics glow. Thus, it demonstrates that modern populism is not a breakdown of communication but a political line as an active psychological mechanism achieved through identity-based alignment.
