Anchoring
Anchoring cognitive bias refers to the human tendency to rely heavily on the first piece of information encountered (the 'anchor') when making decisions. This bias impacts judgment and decision-making processes by disproportionately influencing subsequent thoughts and choices based on the initial anchor point.
How it works
Anchoring occurs when individuals use an initial piece of information to make subsequent evaluations, often subconsciously adjusting perceptions and decisions around this 'anchor.' Even irrelevant or arbitrary anchors can significantly affect one's estimates and decisions, as the initial anchor serves as a mental shortcut in processing complex information.
Examples
- In negotiations, the first price offered can serve as an anchor, strongly influencing the final agreed-upon price.
- When estimating the height of the Eiffel Tower after being primed with a number, individuals often base their guesses around that number, even if it's unrelated.
- Real estate agents may be influenced by the listing price of a property, affecting their assessment of its market value.
Consequences
Anchoring can lead to skewed decision-making and judgment errors. It can make negotiations less flexible, impact financial decisions, and contribute to over- or underestimations of value or risk. Anchoring can distort purchasing decisions and create biases in planning and forecasting activities.
Counteracting
To counteract anchoring, individuals should consciously recognize the potential influence of anchors and deliberately consider multiple perspectives or information sources. Techniques like seeking outside opinions, employing statistical analysis, and developing critical thinking skills can also mitigate the anchoring effect.
Critiques
Some critiques of anchoring suggest that it may not always result from cognitive biases but rather from individuals using reasonable heuristics in complex situations. Additionally, the strength and impact of anchoring can vary significantly based on context, the nature of the task, and individual differences among decision-makers.

Real-world examples showing how Anchoring manifests in practice
Context
A mid-sized retail chain planned to modernize its inventory system and allocated a preliminary budget based on a single vendor’s pitch. The procurement team had limited time and pressure from executives to move quickly so stores could use the new system before peak season.
Situation
The procurement lead received an initial proposal from a well-known software vendor quoting $1.2 million for licensing, implementation, and first-year support. Rather than running a broad RFP, the team invited two additional vendors but continually compared offers back to the $1.2M figure.
The Bias in Action
The procurement team treated the $1.2M proposal as the implicit market price and evaluated later proposals relative to that anchor instead of on absolute value or modular cost components. When a second vendor proposed $980,000, the team framed it as a significant saving and cut deeper into requirements to justify acceptance. A third vendor presented a modular option at $820,000, but discussions kept comparing missing features against the anchored $1.2M package instead of assessing cost per needed capability. Anchoring also influenced the negotiation reserve: negotiators aimed for offers 5–10% below the anchor rather than benchmarking to independent cost estimates.
Outcome
The chain selected the $980,000 vendor after trimming desired customizations, believing they had captured good value relative to the anchor. Six months after rollout, hidden integration costs and several required custom modules raised total spend to $1.06M, only ~12% under the original anchor but ~30% above an independently benchmarked solution that would have met most needs. The rushed, anchor-driven decision delayed full functionality by three months and required a supplementary contract to fix data synchronization issues.
