Anchoring and adjustment is a psychological heuristic where individuals rely heavily on an initial piece of information (the “anchor”) when making decisions. This initial value significantly influences subsequent judgments and estimates, even if the anchor is arbitrary or irrelevant.
Definition
Anchoring and adjustment is a cognitive bias wherein an individual’s decisions are influenced by specific reference points or ‘anchors.’ Throughout the decision-making process, the initial information sets a benchmark, and adjustments are made from this starting point to reach a final decision. This adjustment, however, often remains insufficient, causing a bias towards the initial anchor.
Mathematical Representation
In finance, this can be represented mathematically where an initial estimation \(E_0\) is adjusted by a factor \(a\) to derive a new estimate \(E_1\):
Applications in Business and Finance
Pricing Strategies
In marketing, companies often utilize anchoring by setting high initial prices (reference points) for products during sales periods. Even after discounting, the sale price appears more attractive because consumers compare it to the original anchor price.
Investment Decisions
In finance, anchoring can affect stock market investments. An investor might anchor on the historical high of a stock’s price, influencing their judgment about its current and future value despite market changes.
Historical Context
The concept was popularized by Amos Tversky and Daniel Kahneman, pioneers of the field of behavioral economics. Their research revealed how even arbitrary numbers could influence people’s decisions, leading to systematic deviations from rationality.

FAQs
How does anchoring affect negotiations?
Anchoring can heavily influence negotiations. The initial offer sets a psychological benchmark, impacting the final agreed price or terms. Effective negotiators often use higher or lower anchors to sway agreements in their favor.
Is anchoring always negative?
While anchoring can lead to biased decisions, it isn’t always negative. In some scenarios, it can simplify decision-making and save cognitive resources, especially under uncertainty.

Summary
Anchoring and adjustment is a pervasive cognitive bias affecting decisions across various fields, particularly in business and finance. Recognizing its influence can lead to more informed and rational decision-making processes. Understanding this heuristic’s mechanisms and implications helps mitigate its potential adverse impacts and capitalize on its practical applications.
