Numeric Competencies and Anchoring Biases
نویسندگان
چکیده
Two experiments were conducted to examine the role of three facets of numeracy (objective (ONS), subjective (SNS), and symbolic number mapping (SMap)) in three anchoring tasks (experimenter-given, self-generate, and valuation). We found that the three numeric competencies were associated with different anchoring tasks. SMap was associated with none of the three anchor tasks, while ONS consistently predicted stronger susceptibility to self-generated anchoring. The role of ONS and SNS in experimenter-given and valuation tasks were inconsistent. In Experiment 1, where the direction of adjustment from an anchor is specified, ONS and SNS were positively associated with anchor susceptibility in a valuation task, while they were not in an experimenter-given anchor task. On the other hand, in Experiment 2 where the direction of adjustment from an anchor is uncertain, ONS and SNS were positively associated with anchor susceptibility in an experimenter-given anchor task, while they were not in a valuation task.

Exploring the relationship between knowledge and anchoring effects: is the type of knowledge important?. 1 ABSTRACT Numeric estimates are influenced by a variety of factors including a person's knowledge and the presence of numeric anchors. In general, greater knowledge leads to more accurate estimates and the presence of anchors decreases accuracy. This dissertation is focused on the relations...
متن کاملOrganizational Behavior and Human Decision Processes
Previous research has demonstrated that judgmental anchoring effects—the assimilation of a numeric estimate to a previously considered standard—are semantic in nature. They result because the semantic knowledge about the target object that is activated during the comparison with the anchor influences the absolute judgment. In addition to this semantic influence, the numeric anchor value itself ...
متن کاملMultiple numeric competencies: When a number is not just a number.
A growing body of evidence demonstrates the practical and theoretical importance of numeracy in evaluations and choices involving numeric information, an importance that goes beyond simple accuracy in performing mathematical computations. Numeric competency, however, may be multiply determined, but little research has examined potentially separable influences in evaluations and choice. In the p...
متن کاملAnchoring Revisited: The Role of the Comparative Question
When people estimate a numeric value after judging whether it is larger or smaller than a high or low anchor value (comparative question), estimates are biased in the direction of the anchor. One explanation for this anchoring effect is that people selectively access knowledge consistent with the anchor value as part of a positive test strategy. Two studies (total N = 184) supported the alterna...
متن کاملDe-Biasing User Preference Ratings in Recommender Systems
Prior research has shown that online recommendations have significant influence on users’ preference ratings and economic behavior. Specifically, the self-reported preference rating (for a specific consumed item) that is submitted by a user to a recommender system can be affected (i.e., distorted) by the previously observed system’s recommendation. As a result, anchoring (or anchoring-like) bia...
