Hand-Drawn Videos Reduce Confirmation Bias in Data Interpretation
Watching a chart being drawn by hand helps override prior beliefs and improves accuracy.
Deep Dive
Researchers found that showing hand-drawn construction of bar charts reduces confirmation bias. In a study comparing static charts vs. hand-drawing videos, participants who saw the drawing process interpreted data more accurately even when it conflicted with their prior beliefs. The technique reduced belief-consistent errors and increased belief-overriding responses. Accepted to IEEE VIS 2026.
