Content overview: “Raised Brows and Slow Blinks Make Speakers Look More Confident, Study Finds”. New research published in the Journal of Nonverbal Behavior reveals that subtle facial movements can significantly influence how confident a speaker appears. Elena Martinez at the University of Barcelona, analyzed over 1,200 video clips of people answering questions. Researchers found that two specific actions—raising the eyebrows slightly and blinking slowly—were consistently associated with higher perceived confidence ratings from observers.
In contrast, rapid blinking and a fixed, unexpressive face made speakers seem less sure of themselves. The team used motion-capture technology to isolate these micro-expressions, which often last less than a second. These findings matter because they could help professionals improve public speaking and media training, and they suggest that confidence is not just about words or tone, but also about how the face moves.
