The study measured discernment, which was the difference between the average ratings of true and false articles in either condition.

• Discernment was higher (better) in the accuracy condition group.

• CRT scores (measuring tendency to rely on intuition) positively correlated with discernment. This association was stronger in the accuracy-rating condition.

• Scientific knowledge positively correlated with discernment, with the association being stronger in the accuracy condition. Scientific knowledge was negatively correlated with accuracy ratings and sharing tendency for false headlines.

• Distance from COVID hotspots was uncorrelated with belief in either type of headlines, but it was negatively correlated with sharing behaviors for true and false headlines.

• Medical maximizers (high tendency to use medical treatments) rated both true and false headlines as more accurate than medical minimizers.

• Partisanship was uncorrelated with accuracy discernment. Republicans were less likely to share true and false information than democrats. However, republicans were significantly less likely than democrats to share true information.
