Daniel Kahneman

Daniel Kahneman bridged the gap between psychology and economics, fundamentally changing how we understand human decision-making. His development of Prospect Theory demonstrated that individuals do not always act rationally, but are instead influenced by cognitive biases and loss aversion. This work earned him a Nobel Prize and birthed the field of behavioral economics. In 2025, his insights are applied everywhere from financial market analysis to public policy design, helping governments and businesses create better outcomes by accounting for the predictable irrationality of human behavior.
