A seller’s opening bid or an investor’s purchase price skews later offers and holding decisions.Imagine walking into a clothing store and seeing a jacket marked down from ₹8,000 to ₹4,500. You may immediately feel that ₹4,500 is a good price. Now imagine seeing the same jacket priced at ₹4,500 without any discount. Suddenly, it may not feel quite as attractive. The product has not changed, but the number you saw first has changed how you judge the second number.
This is where Anchoring Bias comes into play. It describes our tendency to rely heavily on the first piece of information we receive when making a decision. That initial figure becomes a reference point, or “anchor”, against which later information is evaluated. In pricing, this can influence what customers consider expensive, affordable, reasonable or even a bargain.
How Anchoring Bias Shapes the Way We See Prices
The idea of anchoring has its roots in the work of psychologists Amos Tversky and Daniel Kahneman. In their well-known 1974 experiment, participants were shown a wheel that landed on either 10 or 65. They were then asked to estimate the percentage of African countries in the United Nations. Although the wheel’s number had nothing to do with the question, participants who saw 65 generally gave higher estimates than those who saw 10. The first number had influenced their judgment.
The same principle appears in everyday shopping. A customer sees a premium product priced at ₹20,000 before seeing a similar product at ₹12,000. The second product may suddenly seem reasonably priced. If the order is reversed, ₹12,000 may feel expensive. The product has not changed; the reference point has.
Retailers and marketers often use this effect when presenting discounts. Showing an original price alongside a reduced price gives customers a clear comparison. A product marked “₹5,000, now ₹3,000” can feel more valuable than a product simply listed at ₹3,000 because the ₹5,000 figure provides context for the lower price. Research and marketing guidance on anchoring commonly point to this role of reference prices in shaping perceptions of value.

Anchoring also matters during negotiations. If a seller quotes ₹10 lakh for a car before the buyer makes an offer, subsequent bargaining is likely to happen around that figure. The buyer may negotiate down to ₹8 lakh or ₹8.5 lakh rather than starting from an entirely independent assessment of the car’s value. Similarly, in business negotiations, the first credible figure can influence the range within which later offers are discussed.
This does not mean that the first number always determines the final decision. People can consider additional information and adjust their judgment. However, those adjustments may still remain influenced by the original reference point. The effect is particularly relevant when people are uncertain, have limited information or need to make a decision quickly.
Anchoring can also work against consumers. In investing, for example, someone may become attached to the price they originally paid for a stock. If the investment later falls, they may continue holding it because they are waiting for it to return to that earlier price, even when current business fundamentals suggest that the investment should be assessed differently.
For businesses, the lesson is not simply to put an inflated number in front of customers. An anchor that feels unrealistic can damage trust rather than strengthen perceived value. Ethical pricing requires the reference point to be genuine and defensible. A premium option, a legitimate previous price or a clearly explained value comparison can provide useful context. A misleading “original price” can do the opposite.
Ultimately, Anchoring Bias reminds us that price is rarely judged in isolation. Customers do not always ask, “What is this objectively worth?” They often ask, consciously or otherwise, “How does this compare with the number I saw first?” That first number can change the way every number that follows feels, making the order in which prices are presented almost as important as the prices themselves.
