On Trivalent Logics, Compound Conditionals, and Probabilistic Deduction Theorems
Angelo Gilio, David E. Over, Niki Pfeifer +1
In this paper we recall some results for conditional events, compound conditionals, conditional random quantities, p-consistency, and p-entailment. Then, we show the equivalence be…
Interpreting connexive principles in coherence-based probability logic
Niki Pfeifer, Giuseppe Sanfilippo
We present probabilistic approaches to check the validity of selected connexive principles within the setting of coherence. Connexive logics emerged from the intuition that conditi…
Probability propagation rules for Aristotelian syllogisms
Niki Pfeifer, Giuseppe Sanfilippo
We present a coherence-based probability semantics and probability propagation rules for (categorical) Aristotelian syllogisms. For framing the Aristotelian syllogisms as probabili…
Probabilities of conditionals and previsions of iterated conditionals
Giuseppe Sanfilippo, Angelo Gilio, David Over +1
We analyze selected iterated conditionals in the framework of conditional random quantities. We point out that it is instructive to examine Lewis's triviality result, which shows t…
Probability Logic
Niki Pfeifer
This chapter presents probability logic as a rationality framework for human reasoning under uncertainty. Selected formal-normative aspects of probability logic are discussed in th…
Probabilistic entailment and iterated conditionals
Angelo Gilio, Niki Pfeifer, Giuseppe Sanfilippo
In this paper we exploit the notions of conjoined and iterated conditionals, which are defined in the setting of coherence by means of suitable conditional random quantities with v…
A Generalized Probabilistic Version of Modus Ponens
Giuseppe Sanfilippo, Niki Pfeifer, Angelo Gilio
Modus ponens (\emph{from and "if then " infer }, short: MP) is one of the most basic inference rules. The probabilistic MP allows for managing uncertainty by transmit…
Abductive, Causal, and Counterfactual Conditionals Under Incomplete Probabilistic Knowledge
Niki Pfeifer, Leena Tulkki
We study abductive, causal, and non-causal conditionals in indicative and counterfactual formulations using probabilistic truth table tasks under incomplete probabilistic knowledge…
Counterfactuals, indicative conditionals, and negation under uncertainty: Are there cross-cultural differences?
Niki Pfeifer, Hiroshi Yama
In this paper we study selected argument forms involving counterfactuals and indicative conditionals under uncertainty. We selected argument forms to explore whether people with an…
Modeling the Ellsberg Paradox by Argument Strength
Niki Pfeifer, Hanna Pankka
We present a formal measure of argument strength, which combines the ideas that conclusions of strong arguments are (i) highly probable and (ii) their uncertainty is relatively pre…
Probabilistic squares and hexagons of opposition under coherence
Niki Pfeifer, Giuseppe Sanfilippo
Various semantics for studying the square of opposition and the hexagon of opposition have been proposed recently. We interpret sentences by imprecise (set-valued) probability asse…
Probabilistic inferences from conjoined to iterated conditionals
Giuseppe Sanfilippo, Niki Pfeifer, David E. Over +1
There is wide support in logic, philosophy, and psychology for the hypothesis that the probability of the indicative conditional of natural language, $P(\textit{if } A \textit{ the…
Transitive reasoning with imprecise probabilities
Angelo Gilio, Niki Pfeifer, Giuseppe Sanfilippo
We study probabilistically informative (weak) versions of transitivity, by using suitable definitions of defaults and negated defaults, in the setting of coherence and imprecise pr…
