Trust experiment: does a story shift your view of your doctor?
NCT ID NCT06526663
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether reading short stories (vignettes) can change how much people trust their primary care doctors. Over 1,100 adults completed a survey measuring trust levels. The goal was to see if trust can be influenced, which may help understand why some people get unnecessary medical care.
