Deepfake vids degrade political reputations even when viewers know they're fake (www.psypost.org)

A recent study published in Communication Research reveals that deepfake videos can harm politicians' reputations, even when viewers suspect the footage is fake. Conducted by researchers from the University of Amsterdam, the study explored how manipulated videos influenced public perception during election cycles. It found that disinformation, often facilitated by AI technology to convincingly alter video content, succeeded in diminishing support for targeted candidates like Representative Nancy Pelosi and Dutch politician Sybrand Buma, regardless of viewers' awareness of the deception. The significance of this research lies in its implication that deepfakes can exploit the psychological concept of processing fluency, where visually compelling content is more readily accepted without critical scrutiny. Although fact-checking interventions failed to reverse the reputational damage caused by the videos, viewers tended to still recognize the falsity of the claims upon reflection. This inconsistency highlights a concerning disconnect where negative emotions toward a politician were triggered despite an awareness of manipulated media. The study underscores the urgent need for effective defenses against AI-generated disinformation, especially in politically polarized environments, as well as a deeper understanding of how such content can shape perceptions and influence democratic processes.
