Discovery of Ambiguity Aversion The concept of ambiguity aversion was first formally identified by economist Daniel Ellsberg in his seminal 1961 paper, famously known as the "Ellsberg Paradox." Through a series of thought experiments, Ellsberg demonstrated that people prefer to bet on outcomes with known probabilities rather than on outcomes where the probabilities are unknown, even when the expected returns are identical. His experiments involved scenarios where participants had to choose between betting on the outcome of draws from urns with known and unknown distributions of coloured balls, revealing a systematic preference for quantifiable risks over ambiguous ones. Definition of Ambiguity Aversion Ambiguity aversion refers to our inclination to shy away from choices with unclear or uncertain outcomes. We tend to favour options where the potential consequences are well-defined and understood. Ambiguity aversion, a concept primarily rooted in behavioural economics and deci
