=== Durability of anchoring === Anchoring effects are also shown to remain adequately present given the accessibility of knowledge pertaining to the target. This, in turn, suggests that despite a delay in judgement towards a target, the extent of anchoring effects have seen to remain unmitigated within a given time period. A series of three experiments were conducted to test the longevity of anchoring effects. It was observed that despite a delay of one week being introduced for half the sample population of each experiment, similar results of immediate judgement and delayed judgement of the target were achieved. The experiments concluded that external information experienced within the delayed judgement period shows little influence relative to self-generated anchors even with commonly encountered targets (temperature) used in one of the experiments, showing that anchoring effects may precede priming in duration especially when the anchoring effects were formed during the task. Further research to conclude an effect that is effectively retained over a substantial period of time has proven inconsistent.
=== Pervasiveness across contexts === One notable characteristic of the anchoring effect is its pervasiveness across diverse judgment scenarios. Furnham and Boo (2011) highlight that anchoring occurs not only in abstract estimation tasks (like guessing the height of Mount Everest) but also in real-world contexts such as legal sentencing, consumer purchasing, salary negotiations, and forecasting. Anchoring persists even when the anchor is implausible or clearly irrelevant (e.g., spinning a random wheel), demonstrating that anchoring can operate automatically, outside of conscious awareness or logical evaluation.
=== Anchoring bias in groups === It is often presumed that groups come to a more unbiased decision relative to individuals. However, this assumption is supported with varied findings that could not come to a general consensus. Nevertheless, while some groups are able to perform better than an individual member, they are found to be just as biased or even more biased relative to their individual counterparts. A possible cause would be the discriminatory fashion in which information is communicated, processed and aggregated based on each individual's anchored knowledge and belief. This results in a diminished quality in the decision-making process and consequently, amplifies the pre-existing anchored biases. The cause of group anchoring remains unsure. Group anchors may have been established at the group level or may simply be the culmination of several individual's personal anchors. Prior studies have shown that when given an anchor before the experiment, individual members consolidated the respective anchors to attain a decision in the direction of the anchor placed. However, a distinction between individual and group-based anchor biases does exist, with groups tending to ignore or disregard external information due to the confidence in the joint decision-making process. The presence of pre-anchor preferences also impeded the extent to which external anchors affected the group decision, as groups tend to allocate more weight to self-generated anchors, according to the 'competing anchor hypothesis'. Recently, it has been suggested that the group member who speaks first often has an unproportionally high impact on the final decision. A series of experiments were conducted to investigate anchoring bias in groups and possible solutions to avoid or mitigate anchoring. The first experiment established that groups are indeed influenced by anchors while the other two experiments highlighted methods to overcome group anchoring bias. Methods that were utilized include the use of process accountability and motivation through competition instead of cooperation to reduce the influence of anchors within groups.
=== Susceptibility in automated systems === Even advanced technologies cannot prevent users from being influenced by anchoring. A peer-reviewed study sought to investigate the effect of business intelligence (BI) systems on the anchoring effect. Business intelligence denotes an array of software and services used by businesses to gather valuable insights into an organisation's performance. The extent to which cognitive bias is mitigated by using such systems was the overarching question in this study. While the independent variable was the use of the BI system, the dependent variable was the outcome of the decision-making process. The subjects were presented with a 'plausible' anchor and a 'spurious' anchor in a forecasting decision. It was found that, while the BI system mitigated the negative effects of the spurious anchor, it had no influence on the effects of the plausible anchor. This is important in a business context, because it shows that humans are still susceptible to cognitive biases, even when using sophisticated technological systems. One of the subsequent recommendations from the experimenters was to implement a forewarning into BI systems as to the anchoring effect.
== Causes == The present literature does not reach a consensus as to the cause of anchoring. However, scholars agree that anchoring is a phenomenon that can be easily demonstrated but is hard to explain. Some scholars suggest that anchoring is, in fact, caused by a combination of factors.
