Daniel Gilbert is a Professor of Psychology at Harvard University whose research has fundamentally changed how we understand human happiness and decision-making. His groundbreaking work explores the surprising science of happiness, revealing why our predictions about what will make us happy are often wrong and how our brains systematically deceive us about our future emotional states. Gilbert's research delves into the psychology of our future selves, examining why we make bad decisions and how our perception of time affects our choices.

His work demonstrates how people consistently overestimate the intensity and duration of future emotions, both positive and negative. Through his studies on psychological immune systems and affective forecasting, he has shown that humans are remarkably poor at predicting their own happiness levels. His findings challenge conventional wisdom about decision-making and reveal the cognitive biases that lead us astray when trying to maximize our well-being.

Gilbert's presentations at major conferences have made complex psychological research accessible to broad audiences, helping people understand the mechanisms behind their choices and the illusions that govern their perception of free will.
