Your experiences are uniquely yours—but how do we truly measure them? In philosophy, "qualia" describe the subjective nature of experience, like how one person feels pain from a jalapeño while another feels pleasure. Research shows that social interactions play a huge role in life satisfaction, yet self-reported data on happiness is flawed. Neuroscience offers a better way—one that reveals how the brain values experiences and what that means for building a more fulfilling life.
