Qualitative Reasoning and Construction of Value in Sequential Judgments

Value judgments often involve numeric estimates. For example, evaluating the nutritional value of a meal involves estimating its calorie content, and bidding in online auctions involves estimating the monetary value of the target items. This research examines value estimates that are derived in a sequential manner, focusing on the susceptibility of these evaluations to anchoring biases. In this context, I identify scenarios in which sequential numeric value judgments are likely to produce an assimilation effect in which subsequent estimates are perceived to be closer to the initially derived one(s). More important, I identify scenarios in which sequential numeric value judgments are likely to result in a contrast effect in which subsequent estimates are perceived to be further away from the initially derived one(s). I attribute these different processes to the implicit classification of the evaluated options into the same or opposite qualitative categories (e.g., virtues vs. vices). I further advance a general theory of assimilation and contrast effects in sequential judgments that builds on the view of information processing as a dual-level process that incorporates both quantitative and qualitative reasoning.
