Abstract
-
This study explores the influence of digital media literacy (DML) and political ideology
on the perceived credibility of fact-checking messages. A 2 2 2 factorial online
experiment was conducted in South Korea and the U.S. to examine the effects of factchecking source (AI vs. human), DML (high vs. low), and political ideology (conservative vs. liberal). While AI-sourced fact-checking messages exhibited a stronger influence among individuals with high DML, human-sourced messages demonstrated
greater efficacy among those with low DML. Contrary to expectations, politically liberal individuals with high DML assigned lower credibility ratings to news articles when
the fact-checking source was AI, compared to human experts. Furthermore, the interaction between fact-checking source and DML was mediated by source likeability.
These findings contribute to our understanding of how individual differences influence responses to fact-checked content and inform targeted fact-checking strategies.
