The Psychology of Manipulation: The Impact of Language Power On Perceived Credibility
Subject area: Arts, Social Sciences and Humanities · Area of research: Psychology

Abstract
This study examined the psychological mechanisms of interpersonal manipulation, specifically focusing on how the "power" of linguistic style influences an individual's perceived credibility. Undergraduate students (N=51) were presented with transcripts of a legal testimony where the independent variable—the "powerfulness" of the speaker's language—was manipulated. One group received a "powerless" version containing hedge words (e.g., "sort of"), intensifiers (e.g., "very"), and fillers (e.g., "you know"), while the other group received a "powerful" version devoid of these markers. We predicted that participants would rate the powerful speaker as significantly more credible than the powerless speaker. Results indicated a strong correlation between linguistic style and perceived authority, consistent with previous findings that social manipulation often operates through subtle, covert cues that bypass strategic reasoning (Franke & van Rooij, 2015). This suggests that credibility is frequently a byproduct of linguistic style rather than factual accuracy.
