Have you ever walked into a store, seen a price tag that says “$200 → now $120!”, and instantly thought, “That’s a great deal” — without really stopping to ask whether the item is actually worth $120? That reaction isn’t random. It’s just your brain doing exactly what it’s wired to do.
The first number you see, which is $200, quietly becomes your reference point. Economists and psychologists call this number an anchor. Once the anchor is set, every other price you see feels expensive or cheap relative to it, not relative to the item’s real value. This mental shortcut is known as the anchoring effect, and it shapes how we shop, negotiate, invest, and even vote. And we often do not realize that at all.
Actually, the anchoring effect exists because humans are not perfectly rational decision-makers. Instead of carefully calculating an item’s true value every time, we rely on heuristics (fast mental shortcuts that save time and effort). Anchoring is one of these shortcuts. When the brain sees an initial number, it treats it as a starting point and makes only small adjustments away from it, even if that number is arbitrary or misleading. As a result, judgments stay biased toward the anchor.
Psychologically, anchoring works because the brain prefers relative thinking over absolute thinking. Evaluating whether $120 is “cheap” or “expensive” on its own requires effort and background knowledge. Comparing $120 to $200 is much easier, so the anchor gives the brain a sense of certainty, even when that certainty is false. Research shows that this effect persists even when people are warned about it, meaning that knowing the anchor is irrelevant and does not fully remove its influence.
This behavior directly contradicts classical economic theory, which assumes that individuals are rational actors who evaluate prices based on objective value, full information, and stable preferences. In a classical model, the initial price should not matter; only the product’s real worth should. The anchoring effect proves that this assumption is unrealistic. People do not discover value independently; instead, value is often constructed in the moment, shaped by context and first impressions.
Behavioral economics replaces the idea of the perfectly rational consumer with a more realistic one: humans are predictable, biased, and influenced by framing. Anchoring shows that markets are driven not only by fundamentals, but also by psychology.
If a simple number shown for a few seconds can change how we perceive value, then anchoring is not just a psychological curiosity; it is a powerful economic tool. Businesses quickly realized that, and by controlling the first price customers see, they can influence how all future prices are judged. This is why anchoring has become a core strategy in marketing.
One of the most common ways companies use is through discount framing. When a store shows “$200 → now $120,” the original price is not shown by accident. The $200 becomes the anchor, signaling to the consumer what the product is supposed to be worth. As a result, $120 feels like a gain rather than a loss, even though the customer is still spending money. In many cases, the original price was never a realistic market price to begin with, but once it appears on the tag, it reshapes perception. Consumers are no longer asking, “Is this worth $120?” but instead, “Am I saving $80?” This shift in thinking dramatically increases the likelihood of purchase. (Even if the item’s worth was actually $70)
Another application appears in pricing tiers, often called the “three options” or “decoy” strategy. Imagine a subscription offered in three versions: Basic for $15, Plus for $40, and Premium for $45. While it may seem that all three options exist to give customers a choice, the highest-priced option often serves a different purpose. Once customers see $45, their brain accepts it as the upper boundary of reasonable pricing. Against that anchor, the Plus option suddenly looks like a smart, balanced choice: only $5 cheaper than Premium, yet almost as feature-rich. As a result, many consumers choose Plus not because it is objectively optimal, but because the anchor makes it feel optimal. The Premium option is less about being sold and more about shaping how the other prices are judged.
Restaurants also rely heavily on anchoring when designing menus. A common strategy is to place the most expensive item, such as a $67 steak, at the top of the menu. This item sets a high anchor, immediately defining the restaurant as “expensive.” When customers then see a $28 pasta dish listed below, it feels relatively affordable and reasonable, even if it would seem expensive in a different context. And again, the restaurant does not expect most customers to order the steak.
Governments often present policies using carefully chosen numerical anchors to shape public approval. For example, instead of emphasizing the total cost of a policy, officials might say, “This policy costs only 1% of GDP” or “The average family pays just $5 more per month.” In financial markets, this effect is especially visible in crypto and stock pricing, where statements like “Bitcoin used to be $69,000” act as powerful anchors that influence investor sentiment and price targets. So, now, you can also see that anchoring is not limited to markets and businesses. It plays a major role in public policy and political communication as well.
And do you know what is more interesting? You still fall for the anchoring trap even though you notice it, even though you know that those numbers are manipulative:)
