Title: Standardizing mean differences: A cautionary tale from a rational choice perspective Abstract: In applied areas of science such as education research or medicine, researchers often report the effect sizes of tested interventions to inform people aiming to decide between these interventions. For continuous outcome variables (such as depression or literacy skills), researchers measure an…

Title: Partial Communication (and, if time allows, Arbitrary Partial Communication) Abstract: While the paradigmatic dynamic epistemic logic (DEL) allows us to reason about agents receiving information from an external source (Public Announcement Logic as well as the Action Models framework), communication within groups of agents has lately become interesting for researchers in the area. This talk discusses…

Title: E is the New P Abstract: How much evidence do the data give us about one hypothesis versus another? The standard way to measure evidence is still the p-value,  despite a myriad of problems surrounding it. In this talk I will provide a gentle introduction to the e-value (wikipedia), a  recently popularized notion of  evidence which overcomes some…

Title: The heuristic use of conditionalisation Abstract: This paper argues that Bayesian conditionalisation should not be viewed as a universal norm of updating, but rather as a heuristic principle that is helpful in some circumstances but fails in others. I go on to show that the heuristic use of conditionalisation can be validated by an…

Title: Conditional logics and labelled proof systems (an introduction) Abstract: Conditional logics, as introduced by David Lewis in 1973, enrich the language of classical propositional logic with a two-places modal operator, the conditional, suitable to represent fine-grained notions of conditionality. After introducing conditional logics and their semantics, that I will define in terms of neighborhood…
