Bruno de Finetti

Bruno de Finetti was an Italian Statistician and Probability theorist known for his revolutionary ideas on subjective probability. He argued that probabilities are not objective truths but personal degrees of belief based on available information. This perspective shifted the focus from classical, frequency-based interpretations of probability to a more individual-centered approach. De Finetti's work laid the foundation for modern Bayesian statistics, where probability is used to quantify uncertainty and update beliefs as new evidence emerges, emphasizing the importance of context and perspective in understanding uncertainty in decision-making and predictions.
