From escapism and joy to catharsis and cerebral engagement, its myriad forms are uniquely versatile and capable of crossing media in a way that seems limitless. The most familiar entertainment motifs, whether social backstabbing, murders or video game strategies, resonate because they touch on fundamental points that the brain was shaped to respond to deeply in order to function in society.
