Preference reversal: Analysis using construal level theory that incorporates discounting

According to the behavioral decision theory, time discounting is often used to explain preference reversals. However, the discounting theory fails to explain some types of preference reversals. Furthermore, preference reversals are limited to those along the time axis (i.e., temporal distance). To extend our knowledge of preference reversals in various choice contexts, this study constructs an analytical framework that combines the time discounting notion of behavioral decision theory and construal level theory developed in social psychology. We put forward three propositions for discounting: magnitude effect (the higher the construal level, the smaller the discounting rate), sign effect (the discounting rate is smaller for losses than for gains), and generalization of distance (discounting applies not only to temporal distance but also to psychological distances such as social distance). These propositions were validated in two studies. In Study 1, we conducted a series of three experiments on a lottery choice task using two samples of respondents (i.e., students and a web panel). In Study 2, we estimated the discounting rates of the higher and lower construal levels by employing multiple intertemporal choice tasks. While many choices involve trade-offs among attributes, the effects of changes in psychological distances are not clear. However, by identifying whether these attributes evoke high or low construal levels and whether the aspects are related to gains or losses, our approach greatly facilitates the analysis of how evaluation and preference are affected by psychological distance, and consequently, that of preference reversal behavior.
