Humans are unlikely to win the animal kingdom’s prize for fastest, strongest or largest, but we are world champions at understanding one another. This interpersonal prowess is fueled, at least in part, by empathy: our tendency to care about and share other people’s emotional experiences. Empathy is a cornerstone of human behavior and has long been considered innate. A forthcoming study, however, challenges this assumption by demonstrating that empathy levels have been declining over the past 30 years.
