Abstract or Description

Similarity and preference theories face similar effects but their methodologies vary enormously. In this paper, we present an explanation of decoy effects using semantic (nonnumerical) stimuli. People had to choose from a set of news the closest to a reference one. We discuss the consequences of the assumptions made by the JDM and similarity communities in explaining context effects.
