# Slightly More Realistic Personal Probability

@article{Hacking1967SlightlyMR, title={Slightly More Realistic Personal Probability}, author={Ian Hacking}, journal={Philosophy of Science}, year={1967}, volume={34}, pages={311 - 325} }

A person required to risk money on a remote digit of π would, in order to comply fully with the theory [of personal probability] have to compute that digit, though this would really be wasteful if the cost of computation were more than the prize involved. For the postulates of the theory imply that you should behave in accordance with the logical implications of all that you know. Is it possible to improve the theory in this respect, making allowance within it for the cost of thinking, or would…

### What Kind of Uncertainty is That? Using Personal Probability for Expressing One's Thinking About Logical and Mathematical Propositions

- Philosophy
- 2012

What is essential for the future development of probability considerations, as for the development of science in general, is that trained minds play upon its problems freely and that those engaged in…

### Logic with numbers

- Philosophy, EconomicsSynthese
- 2006

An alternative, in which the probability axioms are consistency constraints on distributions of fair betting quotients, is proposed, which is a free-standing logic which does not pretend to be a theory of rationality and is therefore immune to, among other charges, that of “logical omniscience”.

### Knowledge of Our Own Beliefs

- Philosophy
- 2015

It is argued that even gross failure to know one's own beliefs need not expose one to sure loss, and does not if the authors follow a generalization of the standard bridge principle between first-order and second-order beliefs.

### Coherent Frequentism: A Decision Theory Based on Confidence Sets

- Mathematics
- 2012

By representing fair betting odds according to one or more pairs of confidence set estimators, dual parameter distributions called confidence posteriors secure the coherence of actions without any…

### The Development of Logical Probability

I shall in the course of this paper investigate some notable attempts to provide a theory of a weak consequence relation ostensibly subsisting between pairs of arbitrarily chosen sentences. At…

### Desirability foundations of robust rational decision making

- Philosophy, EconomicsSynthese
- 2018

This paper provides the theory of desirability with a sound interpretation and with basic notions, and results, for the separation of beliefs and values, and for the case of complete preferences, and discusses the role of conglomerability for the presented theory.

### HAIM GAIFMAN REASONING WITH LIMITED RESOURCES AND ASSIGNING PROBABILITIES TO ARITHMETICAL

There are three sections in this paper. The first is a philosophical discussion of the general problem of reasoning under limited deductive capacity. The second sketches a rigorous way of assigning…

### Real and ideal rationality

- PhilosophyPhilosophical Studies
- 2021

It is argued that there is no way to spell out this contextual account that can make sense of the authors' everyday judgments about rationality, and those who defend probabilistic coherence requirements will need an alternative account of the relationship between real and ideal rationality.
