The Development of Subjective Bayesianism

نویسنده

  • James M. Joyce
چکیده

The Bayesian approach to inductive reasoning originated in two brilliant insights. In 1654 Blaise Pascal, while in the course of a correspondence with Fermat [1769], recognized that states of uncertainty can be quantified using probabilities and expectations. In the early 1760s Thomas Bayes [1763] first understood that learning can be represented probabilistically using what is now called Bayes’s Theorem. These ideas serve as the basis for all Bayesian thought.

Bayesianism and Information

Bayesianism is a theory of inductive inference that makes use of the mathematical theory of probability. Bayesians usually hold that the relevant probabilities should be interpreted in terms of rational degrees of belief. This still leaves much scope for disagreement, since there is no consensus about what norms govern rational degrees of belief. In this chapter, we first provide an introductio...

Sprenger The Renegade Subjectivist : José Bernardo ’ s Reference Bayesianism

This article motivates and discusses José Bernardo’s attempt to reconcile the subjective Bayesian framework with a need for objective scientific inference, leading to a special kind of objective Bayesianism, namely reference Bayesianism. We elucidate principal ideas and foundational implications of Bernardo’s approach, with particular attention to the classical problem of testing a precise null...

How Probabilities Reflect Evidence

Many philosophers think of Bayesianism as a theory of practical rationality. This is not at all surprising given that the view’s most striking successes have come in decision theory. Ramsey (1931), Savage (1972), and De Finetti (1964) showed how to interpret subjective degrees of belief in terms of betting behavior, and how to derive the central probabilistic requirement of coherence from refle...

How uncertain do we need to be ? ?

Expert probability forecasts can be useful for decision making (§1). But levels of uncertainty escalate: however the forecaster expresses the uncertainty that attaches to a forecast, there are good reasons for her to express a further level of uncertainty, in the shape of either imprecision or higher order uncertainty (§2). Bayesian epistemology provides the means to halt this escalator, by tyi...

Subjectivism, Objectivism and Objectivity in Bruno De Finetti’s Bayesianism

The paper will focus on Bruno de Finetti’s position, which combines Bayesianism with a strictly subjective interpretation of probability. For de Finetti, probability is always subjective and expresses the degree of belief of the evaluating subject. His perspective does not accommodate a notion of “objective chance” in the way other subjectivists, including Frank Ramsey, do. To de Finetti’s eyes...
