NCT ID NCT05030883
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether showing who wrote a news article and adding a warning message helps people judge if the news is true or false. Over 300 Dutch Facebook users saw different versions of news posts and answered questions about how accurate they thought the news was. The goal was to learn better ways to fight misinformation online.
