Understanding Anchoring Bias

Have you ever made a decision based on the first piece of information you received? That’s a classic example of anchoring bias. This psychological phenomenon occurs when we rely too heavily on the first piece of information we encounter, which then influences our subsequent judgments and decisions.

What is Anchoring Bias?

Anchoring bias is a type of cognitive bias where individuals depend too much on the initial information they receive (the “anchor”). This can be a number, a fact, or even a suggestion. Once the anchor is set, it can skew our perception and decision-making processes.

Real-Life Examples of Anchoring Bias

• Shopping: Imagine you walk into a store and see a jacket priced at $200. Right next to it, there’s a similar jacket marked down to $100. The $200 price tag serves as an anchor, making the $100 jacket seem like a great deal, even if it’s still overpriced compared to other stores.
• Negotiations: In a salary negotiation, if the employer starts with an initial offer of $50,000, even if the candidate was expecting $60,000, they might end up accepting an offer closer to the anchor due to its influence.
• Medical Decisions: A doctor might present a treatment option with a cost of $1,000 as an anchor. If a patient later hears of a different treatment costing $800, they might perceive it as a bargain, even if both treatments have similar efficacy.

Types of Anchoring Bias

1. Numerical Anchoring: This occurs when specific numbers influence decisions. For example, if you read that a study found that a certain investment has an average return of 10%, you might anchor your expectations around that figure, even if the market conditions change.
2. Relevant Anchoring: This type involves information that is directly related to the decision at hand. For example, if you’re considering buying a used car and the dealer mentions that a similar model sold for $15,000, you may anchor your expectations around that price.
3. Irrelevant Anchoring: Sometimes, even unrelated information can serve as an anchor. For instance, if you’re asked to estimate the number of countries in Africa and first see the number 30, your estimate might skew lower than if you had seen a higher number.

Steps to Overcome Anchoring Bias

• Awareness: The first step is recognizing that anchoring bias exists. Being aware that initial information can unduly influence your judgment is crucial.
• Seek Multiple Sources: Don’t rely on a single piece of information. Try to gather multiple data points or opinions before making a decision. This can help dilute the effect of any one anchor.
• Challenge Your Initial Thoughts: After identifying an anchor, ask yourself how your decision might change if you had received different information. This helps you evaluate the relevance of the anchor.
• Delay Decision-Making: If possible, take a break or give yourself time before making a decision. This can help reduce the emotional impact of the initial anchor.
• Use Objective Criteria: Establish clear criteria for your decisions to minimize the influence of anchors. For example, in negotiations, determine your minimum acceptable offer ahead of time, independent of the anchor presented.

By understanding and recognizing anchoring bias, you can improve your decision-making skills and avoid being misled by misleading first impressions. Whether in shopping, negotiations, or everyday choices, being mindful of this bias can lead to better outcomes.
