Glenn Shafer

Glenn Shafer is a philosopher and statistician known for developing the theory of belief functions, called Dempster-Shafer theory. This framework offers an alternative way to handle uncertainty and evidence, allowing for expressing both specific probabilities and degrees of belief without requiring precise probabilities. Shafer's work helps improve decision-making in situations where information is incomplete or ambiguous, making it valuable in fields like artificial intelligence, forensic science, and risk assessment. His contributions provide a rigorous mathematical foundation for managing uncertain and conflicting evidence, broadening traditional probability methods.
