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…
