  We investigate whether adding specific explanations from fact checking
websites enhances trust in these flags. We experimented with 348 American
participants, exposing them to a randomised order of true and false news
headlines related to COVID 19, with and without warning flags and explanation
text. Our findings suggest that warning flags, whether alone or accompanied by
explanatory text, effectively reduce the perceived accuracy of fake news and
the intent to share such headlines. Interestingly, our study also suggests that
incorporating explanatory text in misinformation warning systems could
significantly enhance their trustworthiness, emphasising the importance of
transparency and user comprehension in combating fake news on social media.
