Anchoring Bias
Anchoring bias is the tendency to rely heavily on the first piece of numerical information you encounter when making a decision. In retail, this is usually the "original" or "regular" price shown before a discount. Once you see that number, every price you evaluate afterward is mentally compared to it — even if the anchor itself was inflated or arbitrary.
First documented by psychologists Amos Tversky and Daniel Kahneman in their research on heuristics and judgment under uncertainty, anchoring is one of the most consistently replicated cognitive biases in behavioral economics.

How Anchoring Works in a Shopping Context

When you walk past a jacket tagged at $249 — now $89, something automatic happens in your brain: the $249 becomes the reference point against which you judge the $89. The discount feels dramatic. The deal feels real. But here's the problem — you probably didn't know what that jacket was worth before you saw the tag.

This is anchoring in action. The anchor doesn't need to be accurate to be effective. It just needs to be present and visible before you start forming your own opinion. In retail environments, that anchor is almost always set by the seller — which means it's set with the seller's goals in mind, not yours.

Anchoring doesn't require deception to work. Even honest retailers benefit from showing a higher reference price simply because it frames the sale price as a win. The psychological contrast does the persuasive work automatically.

“The mind is not designed to evaluate things in absolute terms. It evaluates things relative to a reference point, and the reference point can be manipulated.”

— Daniel Kahneman, Nobel Prize-winning psychologist and author of 'Thinking, Fast and Slow'

Where Reference Prices Come From

"Original price," "regular price," "MSRP," "compare at" — these labels all serve a similar function: they establish a number your brain will treat as the baseline. But each label has a different meaning, and some are more meaningful than others.

  • MSRP (Manufacturer's Suggested Retail Price) is a price the manufacturer recommends — but many retailers routinely sell below it, making MSRP a ceiling rather than a real market price.
  • "Was" or "Original" prices are supposed to represent what the item previously sold for. U.S. regulations in most states require these to reflect actual prior transactions, but enforcement is inconsistent.
  • "Compare at" prices often reflect what the item might cost at a different retailer — a comparison that can be selective or outdated.

Understanding these distinctions is part of reading promotional pricing accurately. Our explainer on sale prices vs. markdowns covers how these labels function differently in practice.

Annual U.S. retail sales influenced by promotional pricing

Promotional and sale events account for a substantial share of U.S. retail volume, underscoring how central reference pricing is to the industry's revenue model.

Over 60%

Shoppers who say discounts influence their purchase decisions

Consumer surveys consistently find that a majority of shoppers are more likely to buy when a discount is displayed, independent of the item's absolute price.

Practical Ways to Reduce the Anchoring Effect

You can't completely switch off a cognitive bias, but you can build habits that reduce its influence on your purchasing decisions.

Research the price before you see the tag

The most effective defense against anchoring is having your own reference point before the retailer sets one for you. Look up the item independently — check multiple sellers, use price-history tools where available, and note what similar products cost. When you arrive at a sale display with your own number in mind, the anchor loses much of its power.

Separate the discount from the value

Ask a different question than "how much am I saving?" — ask "is this price worth paying for what I'm getting?" A 60% discount on something you wouldn't have bought at full price isn't a deal. Anchoring works precisely because it shifts your attention from absolute value to relative contrast.

Account for the full cost

The sale price is rarely the complete picture. Accessories, maintenance, subscriptions, or ongoing costs can significantly change whether a price is genuinely attractive. The total cost of ownership framework gives you a more complete basis for comparison than any single sticker.

Check unit pricing for comparable items

In grocery and household categories especially, unit pricing cuts through promotional framing by expressing cost in consistent, comparable terms. Our guide to unit pricing explains how to use these labels to evaluate actual value rather than deal theater.

Set Your Own Anchor Before You Shop

Before entering a store or browsing a sale page, look up what you expect to pay for the item based on independent research. Write the number down if it helps. When you encounter the retailer's reference price, you'll have a benchmark that isn't theirs — which changes the entire framing of the evaluation.

Why This Matters Beyond Individual Purchases

Anchoring shapes more than individual buying decisions. It influences how people evaluate trade-ins, negotiate salaries, estimate project budgets, and assess real estate offers. In each context, whoever sets the first number gains a structural advantage in framing what follows.

For shoppers, recognizing this pattern is less about suspicion and more about reclaiming the evaluation on your terms. The original price on a tag is a piece of information — but it's information the retailer chose to display, in a specific way, for a reason. Treating it as one data point rather than a fixed truth is a straightforward way to make your purchasing decisions on the basis of actual value rather than engineered contrast.

Frequently Asked Questions

It depends on how the reference price is used. Most U.S. states have regulations requiring that a "was" or "original" price reflect a price the item was actually offered at for a meaningful period. However, enforcement varies significantly, and many reference prices operate in gray areas.

Research the item independently before you see the tag. Check third-party price trackers, manufacturer websites, or retailer history tools. If the "original" price only appears alongside the sale price and nowhere else, that's a signal worth noting.

Yes, and often more aggressively. Online retailers can display crossed-out prices, countdown timers, and "limited stock" badges simultaneously — all of which reinforce the anchor and add artificial urgency. The same skepticism applies.

Awareness helps but doesn't eliminate the effect. Research consistently shows that even people who understand anchoring are still influenced by initial numbers. The most reliable defense is having independent price information before you evaluate a deal.

Ask what the item is worth to you, what it sells for elsewhere, and what the total cost will be over time — including accessories, maintenance, or subscriptions.
