Anchoring Bias: What It Is, and How It Might Impact Your Creative Business

15 min read

Anchoring bias is a common cognitive bias in decision-making. It occurs when individuals heavily rely on an initial piece of information (the “anchor”) to make subsequent judgments and decisions. This psychological phenomenon can significantly influence both personal and business decisions, affecting everything from everyday choices to complex professional judgments. In personal contexts, anchoring bias might sway opinions and financial decisions based on initial impressions or prices, while in business, it can impact negotiations, pricing strategies, and market analyses. Understanding the mechanics and implications of anchoring bias is crucial for making more informed, rational decisions, highlighting the importance of awareness in mitigating its often subtle influence.

Understanding Anchoring Bias

Definition of Anchoring Bias and Its Psychological Underpinnings

Anchoring bias is a cognitive bias that describes the common human tendency to rely too heavily on the first piece of information received (the “anchor”) when making decisions. Originating from the field of behavioral economics and psychological science, it explains how initial information, ideas, or prices set a mental benchmark that heavily influences subsequent judgments and decisions.

The concept of basic anchoring is rooted in the human mind’s tendency to use anchors or reference points for comparative judgment, simplifying the complex task of assessing value or making decisions. Anchoring occurs even when the initial information is arbitrary or irrelevant, showing how our perceptions, decisions, and ability to arrive at a correct final answer can be skewed by initial impressions.

Explanation of How Anchoring Bias Works in the Human Mind

Anchoring bias operates by establishing a reference point in the mind, which then influences how new information is interpreted and valued. Once an anchor is set, there is a natural tendency to interpret other information around this anchor.

This process often occurs subconsciously, leading individuals to give disproportionate weight to the first information they receive. For example, when given an initial price or value, people tend to make adjustments based on this anchor, but these adjustments are typically insufficient, leaving their final decision closer to the initial anchor than it might be otherwise.

This bias is a result of the mental heuristic, or shortcut, that the brain uses to save time and effort in decision-making.

Selective Accessibility and Anchoring Bias

In the context of anchoring bias and decision-making, the concept of “selective accessibility” refers to a cognitive process where individuals selectively access or retrieve information that is consistent with a previously established anchor. This concept is part of the explanation for why and how anchoring bias occurs. Here’s a breakdown of how selective accessibility works.

Initial Anchor Establishment: When an individual is presented with an initial piece of information or value (the anchor), it sets a mental benchmark.

Selective Retrieval of Information: Following the establishment of this anchor, when the individual is making a judgment or decision, they unconsciously access information that is consistent or congruent with the anchor. This selective retrieval happens because the anchor influences which aspects of their knowledge or memory are activated.

Biased Interpretation and Judgment: The information that aligns with the anchor is more readily brought to mind and given undue weight in the decision-making process. As a result, the individual’s subsequent judgment or estimate is biased toward the anchor. This happens even if the anchor is arbitrary or irrelevant to the task at hand.

Confirmation of the Anchor: The process of selectively accessing information that supports the anchor can lead to a form of confirmation bias, where the individual feels more confident in their decision or judgment because it seems to be supported by the information they have accessed.

Selective accessibility is a key mechanism in explaining why anchoring effects occur. It illustrates how our cognitive processing is not always objective or comprehensive but can be skewed by initial inputs, leading to biased outcomes in judgments and decisions.

Examples of the Anchoring Effect in Everyday Situations

Anchoring bias manifests in various everyday situations. In personal finance, an initial price offered for a car or house can set an anchor, affecting how reasonable subsequent prices appear, regardless of the actual market value.

In shopping, the original price on a tag sets an anchor, making the discounted price seem more attractive, irrespective of the product’s true worth. In negotiations, the first offer typically sets the stage for the discussion that follows, often influencing the final agreement more than the objective data should allow.

Even in social situations, early information about a person (like a first impression) can serve as an anchor, influencing how their future behavior is perceived. These anchoring bias examples illustrate how anchoring bias can subtly influence a wide range of everyday decisions and perceptions.

Differences Between Anchoring Bias and the Anchoring and Adjustment Heuristic

These concepts are related but slightly different. The Anchoring and Adjustment Heuristic is a cognitive strategy or mental shortcut that people often use when making judgments or decisions. It involves starting with an initial “anchor” or reference point and then adjusting one’s judgment or decision from there.

The adjustment from the initial value may not be sufficient, leading to biased or inaccurate conclusions. For example, if you’re asked whether the population of a city is more or less than 1 million, and you anchor on 1 million, your subsequent estimate is likely to be influenced by that anchor.

Anchoring Bias is a specific cognitive bias that occurs when individuals rely too heavily on the initial anchor or reference point when making judgments or decisions. It leads people to insufficiently adjust from the anchor, resulting in systematic errors. The anchoring bias is a cognitive phenomenon that illustrates the limitations and biases in human decision-making.

The Adjustment and Anchoring Heuristic is the mental process people use, while the Anchoring Bias is the specific cognitive bias that can result from using this heuristic. The bias occurs when the adjustment from the anchor is insufficient, leading to errors in judgment or decision-making. Both concepts are important in understanding human behavior and decision-making processes.

Internal vs External Anchors

In the context of decision-making and the anchoring bias, anchors can be categorized as either internal or external. The distinction between them lies in the source of the initial information or value that influences subsequent judgments and decisions.

Internal Anchors

Internal anchors originate from an individual’s existing knowledge, beliefs, or experiences. They are based on personal perceptions or past information that the individual brings to a decision-making situation.

Example: If you are estimating the value of a house, an internal anchor might be the price you paid for your own home. Your estimate would be influenced by this personal experience, regardless of the current market trends or the specific features of the house in question.

Internal anchors are subjective and can vary greatly from one person to another, depending on their unique experiences and knowledge base. They are often less visible to others as they are formed by personal cognition.

External Anchors

External anchors are provided by the external environment or other people. They are not based on the individual’s prior knowledge or experiences but are introduced during the decision-making process.

Example: If a real estate agent suggests that a house is worth $500,000, this figure becomes an external anchor. Your subsequent valuation of the house might gravitate towards this suggested price, even if other data suggests a different value.

External anchors are often more uniform among different individuals in the same situation since they are influenced by the same external information. They are visible and measurable, such as a listed price or a recommendation.

Understanding the distinction between internal and external anchors is crucial as it helps to identify the sources of potential biases in decision-making. While external anchors are more straightforward to identify and potentially counteract, internal anchors require self-awareness and reflection to recognize and mitigate. Both types of anchors can significantly impact judgments and decisions, and an awareness of their presence is key to making more informed and objective choices.

How Does Expertise or Emotional State Influence the Intensity of the Anchoring Effect?

The intensity of the anchoring effect can be influenced by various factors. Both emotional state and expertise influence judgmental anchoring effects. Put simply, while expertise in a relevant field can reduce the influence of the anchoring effect, it does not confer complete immunity, especially when experts are dealing with uncertainty or information outside their domain.

Similarly, emotional states significantly impact the anchoring effect, with positive emotions potentially reducing its influence and negative emotions possibly enhancing it. Understanding these influences is crucial for mitigating the impact of anchoring bias in decision-making.

Let’s explore in further detail how each of these factors plays a role.

Expertise and the Anchoring Effect

Experts in a specific field are often less susceptible to the anchoring effect in their area of expertise. This is because they possess more knowledge and experience, enabling them to rely less on external anchors and more on their own understanding and data analysis.

However, the reduction in susceptibility is context-specific. Experts can still be influenced by anchoring in areas outside their domain of expertise. Even within their field, under conditions of uncertainty or complexity, experts might still fall back on anchors as cognitive shortcuts.

There is also a risk of overconfidence among experts, where they might overlook the anchoring bias, assuming that their expertise makes them immune to it. This overconfidence can lead to an inadvertent reliance on anchoring, especially in fast-paced or high-pressure situations.

Emotional State and the Anchoring Effect

An individual’s mood or emotional state can significantly influence the intensity of the anchoring effect. Research suggests that positive emotions can enhance creativity and cognitive flexibility, potentially reducing susceptibility to anchoring by allowing for more comprehensive evaluation of information.

Conversely, negative emotional states might increase reliance on anchors. For instance, anxiety or stress can lead to a greater dependence on cognitive shortcuts like anchoring effects, as these states narrow the focus of attention and reduce the capacity for complex decision-making.

The ability to regulate emotions effectively can play a role in mitigating the anchoring effect. Emotionally intelligent individuals, who can manage their emotions and remain calm and clear-headed, are likely to be less influenced by irrelevant anchors.

Positive Effects of Anchoring Bias

Anchoring affects people both positively and negatively. While often considered a cognitive flaw, anchoring bias can, under certain circumstances, streamline decision-making processes, leading to efficient and pragmatic conclusions. In situations where rapid decisions are necessary, and exhaustive analysis is impractical, relying on an initial anchor can be a useful heuristic.

For instance, in emergency decision-making scenarios, the first piece of information can act as a crucial anchor, helping to quickly form a response strategy. In these cases, the ability to make swift judgments based on the original anchoring point can be more beneficial than a delayed decision due to over-analysis. Anchoring simplifies the complex cognitive process of assessing and comparing vast amounts of information, thereby helping one arrive at the correct answer more quickly.

Beneficial Aspects of Anchoring Bias in Specific Situations


In negotiations, the use of anchoring can be a powerful tactic. A party that makes the first offer effectively sets an anchor that can strongly influence the negotiation’s direction. This can be particularly advantageous when the initial offer is based on reasonable and well-researched data, as it can set a realistic framework for the ensuing negotiation.

First Impressions

First impressions, while a form of anchoring, can sometimes work favorably, especially in social or professional networking. A strong and positive first impression can set an anchor that influences subsequent interactions, leading to beneficial relationships or collaborations. For instance, a positive initial meeting with a client can anchor their overall perception of a professional relationship.

Consumer Behavior

In retail, anchoring can benefit consumers by simplifying choices in a market flooded with options. Retailers often use price anchoring to guide consumers toward making a purchase decision that feels like a good deal. For consumers, this simplifies shopping by creating a perceived value against which they can judge their purchase.

In these contexts, anchoring bias, when recognized and managed appropriately, can be a useful tool in guiding decision-making towards desirable outcomes.

Negative Effects of Anchoring Bias

Drawbacks in Personal and Professional Decisions

Anchoring bias can lead to several drawbacks in both personal and professional decision-making scenarios. In personal decisions, such as buying a house or car, anchoring to the initial price can hinder one’s ability to negotiate effectively or recognize a fair market price, potentially leading to overpayment or missed opportunities.

In professional settings, anchoring bias can result in flawed business decisions. For instance, anchoring to an initial sales target or a past performance metric without considering current market dynamics can lead to unrealistic goals or strategies. This bias limits the ability to adapt to new information or changing circumstances, as initial anchors can overshadow subsequent, potentially more relevant data.

Impact on Critical Thinking and Rational Decision-Making Processes

Anchoring bias significantly affects critical thinking and rational decision-making. It can lead to a narrow focus, where individuals or teams become fixated on the initial information and fail to fully consider additional data or perspectives. This tunnel vision can impede a comprehensive analysis of situations, leading to decisions that are not optimally informed or balanced.

In complex decision-making scenarios, where multiple factors and variables must be weighed, anchoring bias can oversimplify the process, reducing the quality and depth of analysis. This can result in decisions that are based more on initial perceptions or assumptions rather than a rational evaluation of all available information.

Examples of Negative Outcomes Due to Anchoring Bias

In financial investments, investors might anchor on the initial purchase price of a stock, which can lead to holding onto a losing investment for too long or selling a profitable one too soon.

When anchoring bias occurs in the legal field, it can affect the decision-making process by the judge or jury. In such cases, the first piece of evidence or an initial argument might unduly influence the final judgment.

In healthcare, a doctor may anchor on a specific diagnosis based on initial symptoms, potentially overlooking other medical explanations or necessary tests, leading to misdiagnosis.

These examples underscore the potentially detrimental impact of anchoring bias across various domains, highlighting the importance of awareness and strategies to mitigate its influence in decision-making processes.

Studies on the Anchoring Effect

The following studies provide a comprehensive overview of the anchoring effect, illustrating its impact in various contexts, from legal judgments to subjective assessments and decision-making processes.

“Anchoring Effects in the Assessment of Papers” (Bornmann L, Ganser C, & Tekles A, 2021)

This study empirically investigated the assessment of cited papers within the framework of the anchoring-and-adjustment heuristic. It explored whether the assessment of a paper could be influenced by numerical information acting as an anchor, such as citation impact​​. Learn more about the study’s findings here.

“Influence of Anchoring on Court Sentences by Experienced Judges” (Englich, Mussweiler, & Strack, 2005)

This study examined how experienced judges, despite their expertise, were still susceptible to the anchoring effect. The research found that even legal experts could be influenced by irrelevant numerical anchors when making sentencing decisions. Learn more about the study’s findings here.

“Adjusting Inadequately” (Epley & Gilovich, 2006)

This study focused on how people often fail to adjust sufficiently from an anchor, leading to biased judgments and decisions. It explored the cognitive mechanisms behind why people stick close to the anchor even when it’s irrelevant or arbitrary.

“Anchoring in the Assessment of Subjective Probability Distributions” (Tversky & Kahneman, 1974)

This classic study by Amos Tversky and Daniel Kahneman is one of the foundational works in the field. It demonstrated how people’s estimates of probability distributions are influenced by initial values (anchors), impacting their judgment and decision-making.

Anchoring Bias in Individual Decision-Making

Anchoring bias significantly impacts individual decision-making by influencing how people assess and interpret information. When an individual encounters an initial piece of information, such as a price, statistic, or opinion, this information often becomes an anchor that disproportionately influences their subsequent thoughts and decisions.

For example, if a person hears a salary figure before negotiating their pay, that number can strongly impact their expectations and negotiation strategy, regardless of their qualifications or the job’s market value. Similarly, in everyday judgments, such as estimating the time needed for a task or assessing the probability of an event, the first piece of information encountered tends to skew perception and can lead to inaccuracies.

Impact on Personal Finance, Purchasing Decisions, and Lifestyle Choices

In personal finance, anchoring bias can lead to suboptimal financial decisions. For instance, investors might anchor on the initial purchase price of a stock and make selling or holding decisions based on this anchor rather than current market analysis.

In purchasing decisions, retail prices often serve as anchors, influencing consumers’ perceptions of value and leading them to overspend or miss better deals. Lifestyle choices, such as choosing a health insurance plan or a retirement savings goal, can also be swayed by anchoring bias, where initial suggestions or historical choices unduly influence current decisions.

Avoiding the Enigmatic Anchoring Effect in Your Personal Life

The first step in avoiding anchoring bias is awareness. Recognize that initial information can unconsciously influence judgments and actively question its relevance and validity.

Before making a decision, gather information from various sources. This helps in diluting the effect of any single anchor. If possible, take time before making important decisions to minimize the influence of an initial anchor. Discussing decisions with people who are not exposed to the same anchors can provide more objective insights.

Analyzing past decisions for evidence of anchoring bias can help in identifying personal tendencies and adjusting future decision-making processes. By understanding and actively managing the influence of anchoring bias, individuals can make more balanced and rational choices in their personal and financial lives.

Anchoring Bias in Business Contexts

Anchoring bias plays a significant role in business decision-making and negotiations. Business leaders and negotiators often rely on the first piece of information received as a reference point, which can heavily influence the final decision or agreement. For instance, in salary negotiations, the initial offer sets an anchor that impacts the entire negotiation process.

The anchoring effect can also influence strategic business decisions, such as mergers and acquisitions, where the initial valuation or proposal can unduly influence final agreements, potentially leading to overvaluation or undervaluation. Recognizing and managing this bias is crucial to ensure that business decisions are based on comprehensive analysis and not just influenced by initial figures or opinions.

Impact on Pricing Strategies, Marketing, and Consumer Behavior

In marketing and pricing strategies, anchoring bias significantly affects consumer perception and behavior. Retailers often use initial price anchors to make subsequent prices seem more attractive, influencing consumers’ perceptions of value and bargain.

For example, showing the original price slashed next to a sale price can create a strong anchor, making the sale price seem like a significant deal regardless of its actual market value. This strategy is prevalent in e-commerce and traditional retail settings. In marketing, promotional campaigns often use anchoring to shape consumer expectations and perceptions of a product or service.

Demonstrating the Influence of Anchoring Bias on Business Outcomes

A study in real estate showed how listing prices serve as anchors that affect both the seller’s and buyer’s perception of property value, often leading to price rigidity or unrealistic market expectations.

In stock markets, the initial offering price of an IPO can act as an anchor for investors, influencing their valuation of the stock independent of its fundamental value. This anchoring can lead to over- or under-pricing of the stock in its early trading days.

A well-known electronics company introduced a high-end product at a significantly high price, establishing an anchor. Subsequently, slightly lower-priced versions seemed more reasonably priced to consumers, increasing their sales, despite being higher than the average market price for similar features.

These examples underscore the pervasive influence of anchoring bias in various business contexts. Understanding and mitigating this bias is essential for accurate decision-making, effective negotiation, strategic pricing, and marketing within the business environment.

Mitigating the Effects of Anchoring Bias

Mitigating the impact of anchoring bias requires a conscious effort to recognize and adjust for its influence in decision-making processes, both at an individual and organizational level.

Critical Evaluation of Anchors: Actively question the relevance and source of any initial information or anchor. Assess whether it is based on empirical data or arbitrary.

Gathering Comprehensive Information: Before making decisions, especially significant ones, gather a wide range of data and opinions. This broader perspective can dilute the influence of any single anchor.

Seeking External Opinions: Consulting with unbiased third parties can provide fresh perspectives free from the initial anchors that may influence internal decision-makers.

Use of Structured Decision-Making Processes: Implementing structured processes that require thorough analysis can help in identifying and mitigating the effects of anchoring bias. These processes encourage a more balanced evaluation of all available information.

Workshops and Training Sessions: Regular training programs for individuals and teams on cognitive biases, including anchoring bias, can raise awareness and provide tools to manage its impact.

Role-Playing and Scenario Analysis: Engaging in role-playing exercises or analyzing past decisions where anchoring bias was at play can be effective in demonstrating its effects and teaching ways to counteract it.

Incorporating Bias Training in Onboarding: Integrating cognitive bias awareness into employee onboarding processes ensures that new team members are equipped to recognize and deal with these biases from the start.

Checklists and Standard Operating Procedures: Developing checklists and standard procedures for decision-making can ensure that multiple aspects and perspectives are considered, reducing reliance on any single piece of information.

Decision Support Systems: Utilizing software or decision support systems that analyze data using algorithms can help minimize the subjective influence of human biases, including random anchors that might skew data and produce significant consequences for your organization.

Regular Review and Feedback Mechanisms: Establishing a culture where decisions are regularly reviewed and feedback is encouraged can help in identifying instances of anchoring bias and refining decision-making processes over time.

By employing these techniques, training, and tools, both individuals and organizations can significantly reduce the impact of anchoring bias, leading to more rational and objective decision-making.

Final Thoughts on Anchoring Bias

Anchoring bias is a pervasive cognitive phenomenon that significantly influences decision-making in both personal and professional contexts. Characterized by the tendency to rely too heavily on an initial piece of information, anchoring bias can skew judgments and lead to suboptimal outcomes.

While it can sometimes facilitate efficient decision-making, more often, it poses challenges by impacting critical thinking and rational analysis, especially in complex scenarios like business negotiations, pricing strategies, and personal finance. Awareness and active management of this bias through techniques such as critical evaluation of information, structured decision-making processes, and comprehensive training programs are essential for mitigating its effects.

Understanding and addressing anchoring bias is not only crucial for making more informed and objective decisions but also for fostering a culture of balanced and nuanced thinking in various aspects of life and business.
