Indeterminate Truth and Credences

We investigate the supervaluational Kripkean account of truth and show how it can apply to finding rational indeterminate credences in undermining scenarios.

Accurate Updating for the Risk-Sensitive

We argue that accuracy-theoretic considerations still tell the risk-sensitive to update by conditionalization.

Strict Propriety is Weak

We note that strict propriety follows from weak propriety, given truth-directedness, thus closing an argumentative gap in the literature.

Avoiding Risk and Avoiding Evidence

This argues that evidence gathering is epistemically irrational for the (Buchak-style) risk-avoidant agent. To do this we consider how accuracy should be measured once risk-awareness is rationally permissible.

Believing Probabilistic Contents

We show that Moss’s model of uncertainty is at least as expressively powerful as every other current imprecise probability framework. And we give a Dutch Book argument for certain failures of consistency.

Limits in the Revision Theory. More Than Just Definite Verdicts

This provides a new proposal for what to do at limit stages of the revision theory of truth: one shouldn’t only consider definite verdicts that are brought about, but more general closed properties. This is important if one wishes to consider a revision theory for probability.

Probability for the Revision Theory of Truth

We investigate how to assign semantic probability values to sentences by tracking how often a sentence is true in transfinite sequences; particularly sequences from Gupta and Belnap’s revision theory of truth.

Self-Referential Probability

This thesis discusses self-referential probabilities in some gory detail. We discuss a number of semantics models and initial work on how rationality considerations should apply in such cases.

Rational Probabilistic Incoherence. A Reply to Michael Caie

In addition to specific responses to Caie’s paper, this presents some bullets that need to be bitten if one adopts a consequentialist view of epistemic utility. Further such bullets are also presented in my thesis (ch.7)

How to Express Self-Referential Probability. A Kripkean Proposal

This presents a Kripke-style construction for a language with self-referential probability as well as an ω-complete axiomatisation. It also follows Stern in arguing that principles like introspection should be formulated using a truth predicate.
