The Impact of Women's Tears on Men's Aggression: A Groundbreaking Study

A groundbreaking study published in PLOS Biology reveals that human tears have the ability to reduce aggression in men and alter brain activity. The research challenges the belief that tears are solely for eye protection and suggests that they play a significant role in human social interaction. The study found that exposure to tears led to a 43.7% reduction in aggression among male participants compared to saline. The experiments also showed that certain olfactory receptors in the human nose can detect tear signals, even though tears themselves lack a noticeable smell. The findings highlight the potential importance of tears in social signaling and provide insights into the connection between smell and aggression.
