People's estimates of uncertain quantities are commonly influenced by irrelevant values. These anchoring effects were originally explained as insufficient adjustment away from an initial anchor value. The existing literature provides little support for the postulated process of adjustment, however, and a consensus that none takes place seems to be emerging. We argue that this conclusion is premature, and we present evidence that insufficient adjustment produces anchoring effects when the…

Are Adjustments Insufficient?

TLDR
Evidence is provided of adjustment-based Anchoring effects similar to the accessibility-based anchoring effects observed in the traditional anchoring paradigm, supporting theories of social judgment that rely on mechanisms of insufficient adjustment.

The Anchoring-and-Adjustment Heuristic

TLDR
The results of two sets of experiments indicate that adjustments from self-generated anchor values tend to be insufficient because they terminate once a plausible value is reached unless one is able and willing to search for a more accurate estimate.

When effortful thinking influences judgmental anchoring: differential effects of forewarning and incentives on self‐generated and externally provided anchors

Two experiments examined the impact of financial incentives and forewarnings on judgmental anchoring effects, or the tendency for judgments of uncertain qualities to be biased in the direction

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

TLDR
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.

Integrating information from multiple sources: A metacognitive account of self-generated and externally provided anchors

Estimates of unknown quantities are influenced by both self-generated anchors (SGAs) and externally provided anchors (EPAs; e.g., the advice of others). It was hypothesised that people use the degree

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

Considering The Impossible: Explaining The Effects of Implausible Anchors

Research on judgmental anchoring - the assimilation of a numeric estimate towards a previously considered standard - has demonstrated that implausible anchors produce large effects. We propose an

The limits of anchoring.

Anchoring and adjustment is a pervasive bias in which decision makers are influenced by random or uninformative numbers or starting points. As a means of understanding this effect, we explore two

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

The illusion of transparency: biased assessments of others' ability to read one's emotional states.

TLDR
Three sets of studies provide evidence for an illusion of transparency, or a tendency for people to overestimate the extent to which others can discern their internal states, and the implications of this illusion for people's reluctance to intervene in emergencies.

The spotlight effect in social judgment: an egocentric bias in estimates of the salience of one's own actions and appearance.

TLDR
Evidence is provided that people overestimate the extent to which their actions and appearance are noted by others, a phenomenon dubbed the spotlight effect, and that people appear to anchor on their own rich phenomenological experience and then adjust to take into account the perspective of others.
