Relevance and Reason Relations


Skovgaard-Olsen, Niels; Singmann, Henrik; Klauer, Karl Christoph (2016). Relevance and Reason Relations. Cognitive Science, 41:1202-1215.

Abstract

This paper examines precursors and consequents of perceived relevance of a proposition A for a proposition C. In Experiment 1, we test Spohn's (2012) assumption that ∆P = P(C|A) − P(C|~A) is a good predictor of ratings of perceived relevance and reason relations, and we examine whether it is a better predictor than the difference measure (P(C|A) − P(C)). In Experiment 2, we examine the effects of relevance on probabilistic coherence in Cruz, Baratgin, Oaksford, and Over's (2015) uncertain “and-to-if” inferences. The results suggest that ∆P predicts perceived relevance and reason relations better than the difference measure and that participants are either less probabilistically coherent in “and-to-if” inferences than initially assumed or that they do not follow P(if A, then C) = P(C|A) (“the Equation”). Results are discussed in light of recent results suggesting that the Equation may not hold under conditions of irrelevance or negative relevance.
