The anchoring-and-adjustment heuristic has been used to account for a wide variety of numerical judgments. Five studies show that adjustment away from a numerical anchor is smaller if the anchor is precise than if it is rounded. Evidence suggests that precise anchors, compared with rounded anchors, are represented on a subjective scale with a finer resolution. If adjustment consists of a series of iterative mental movements along a subjective scale, then an adjustment from a precise anchor…

How Multiple Anchors Affect Judgment: Evidence from the Lab and eBay

The vast majority of anchoring research has found that judgments assimilate toward single anchors, but no papers have directly compared the impact of one anchor with that of multiple anchors. We

The Effect of Accuracy Motivation on Anchoring and Adjustment: Do People Adjust from Provided Anchors?

It is shown that although accuracy motivation fails to increase the gap between anchors and final estimates when people are uncertain about the direction of adjustment, accuracy motivation does increase anchor-estimate gaps whenPeople are certain about thedirection of adjustment.

Anchoring on the "here" and "now" in time and distance judgments.

Time and distance estimates were elicited with either unit-based (e.g., "How many days until...") or end-based questions and reliance on larger units yielded higher estimates and warning about insufficient adjustment reduced the effect.

Anchoring Effects: Types, Influential Factors and Intervention Measures

Anchoring effects refers to a phenomenon that an irrelative anchor biases a subsequent numerical judgment under uncertain circumstances. The influencing factors and intervention measures vary

“€14,875?!”: Precision Boosts the Anchoring Potency of First Offers

In negotiations, higher first offers from sellers drive up sale prices—reversely, buyers benefit from lower first offers. Whereas abundant research has replicated this robust anchoring effect of

The Precision Effect in Numbers: How Processing Fluency of Numbers Influence Response Confidence

Previous research has shown that precise numbers (e.g., 365,564) are judged to be smaller than round numbers of comparable magnitude (e.g., 365,000). In this research, we suggest that this precision

The too-much precision effect: When and why precise anchors backfire with experts

Past research has suggested a fundamental principle of price precision: The more precise an opening price, the more it anchors counteroffers. The present research challenges this principle by

The Too-Much-Precision Effect

This research disentangles competing theoretical accounts (attribution of competence vs. scale granularity) and qualifies two putative truisms: that anchors affect experts and amateurs equally, and that more precise prices are linearly more potent anchors.

Anchoring in Payment: Evaluating a Judgmental Heuristic in Field Experimental Settings

Anchoring, the biasing of estimates toward a previously considered value, is a long-standing and oft-studied phenomenon in consumer research. However, most anchoring work has been in the lab, and the

Putting Adjustment Back in the Anchoring and Adjustment Heuristic: Differential Processing of Self-Generated and Experimenter-Provided Anchors

Evidence is presented that insufficient adjustment produces anchoring effects when the anchors are self-generated, and it is suggested it is time to reintroduce anchoring and adjustment as an explanation for some judgments under uncertainty.

Results of four studies support the notion that anchoring effects are mediated by mechanisms of hypothesis-consistent testing and semantic priming. According to the suggested Selective Accessibility

Flexible correction processes in social judgment: the role of naive theories in corrections for perceived bias.

The flexible correction model posits that corrections occur when judges are motivated and able to adjust assessments of targets according to their naive theories of how the context affects judgments of the target(s).

Three heuristics that are employed in making judgements under uncertainty are described: representativeness, availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development.

Abstract : Ambiguity results from having limited knowledge of the process that generates outcomes. It is argued that many real-world processes are perceived to be ambiguous; moreover, as Ellsberg
