Researchers found that exposure to sexist comments significantly alters how women interact emotionally during teamwork, increasing a key ingredient of successful collaboration: emotional synchrony. Emotional synchrony—shared, temporally aligned facial expressions among team members—has long been known to enhance trust, coordination, and performance.
