I have something to admit: I’m a bit of a food snob. Not in the sense that I like eating in fancy restaurants, but I do have a weakness for beautiful packaging. Last week, I bought a bottle of olive oil that cost three times what I would normally spend. I told myself it was because the quality was better. And maybe it was. But the honest truth? The bottle is just really, really nice. And that’s what drew me in.
But here’s what I didn’t realise at the time: the price didn’t just justify the purchase, it actually changed how much I enjoyed it. Because if that same beautiful bottle had cost the same as the one next to it on the shelf, I probably wouldn’t have valued it in the same way. Even if the oil inside had been identical.
This is one of the most robust findings in behavioural economics: Price doesn’t just reflect value. It amplifies it.
Researchers at Stanford and Caltech ran a study in which participants tasted the same wine but were told it cost either five dollars or forty-five dollars a bottle. Not only did people report enjoying the expensive wine more, brain imaging showed that their reward centres were more active when they thought they were drinking the pricier bottle. The experience itself changed. The price tag was not a label. It was an ingredient.
Psychologist Richard Thaler, whose work on mental accounting won him the Nobel Prize, has spent decades documenting how people do not evaluate prices in absolute terms but in relation to reference points. What something costs is always interpreted against what we expected it to cost, what we paid for something similar before, and what alternatives are available. A fifteen euro glass of wine at an airport feels reasonable. The same glass in your local neighbourhood bar feels like an insult. Same wine, same price, completely different experience.
This is why pricing is one of the most powerful and most underestimated design decisions a business can make. Most organisations treat pricing as a financial exercise: calculate costs, add margin, arrive at a number. But the number you arrive at does not just determine your revenue. It shapes what customers believe your product is worth, how they feel while using it, and whether they come back.
The implications run in both directions. Pricing too low does not just reduce margin. It actively undermines perceived quality. Customers who pay less are, counterintuitively, often less satisfied, because the price has already told them not to expect much. Luxury brands have understood this for decades. IKEA understands the inverse of it just as well. The pricing strategy is inseparable from the brand strategy because price is the most immediate signal of what something is.
What I find most interesting behaviourally is how this plays out in services rather than products. When a consultant raises their day rate, clients often become more attentive, more prepared, more engaged. The higher price has changed the context of the relationship. The same advice, delivered at a higher price, lands differently. Not because the advice changed. Because the price changed what the client brought to the room.
How to use this insight:
Before setting or changing a price, ask what signal that price sends before a single interaction has taken place.
If you are pricing too low out of fear of rejection, consider what that price is communicating about the quality of what you offer. A low price is not a neutral choice. It is an active claim about value, and it shapes how customers experience what they buy.
If you are reviewing your pricing and considering a raise, think about the full effect. Higher prices often attract more committed customers, generate fewer complaints, and produce better outcomes because clients invest more attention and effort when they have paid more. The price changes the behaviour on both sides of the transaction.
For product designers and marketers: the way a price is presented matters as much as the price itself. A price shown as a daily cost rather than an annual sum feels smaller. A price anchored next to a higher alternative feels reasonable. A price with a clear explanation of what it includes feels fairer than the same price offered without context. None of this is manipulation. It is an acknowledgement that price perception is a psychological experience, not a mathematical one.
The bottle of olive oil was probably worth the extra cost. But even if it had not been, the price would have made it taste like it was. And did I mention the bottle is really nice? That has to count for something too, right?
Behavioural Design Fundamentals Course: 25 & 26 June, Amsterdam
Pricing is choice architecture. So is product design, service design, internal communication, and almost every decision you make about how you ask people to do anything.
The Fundamentals Course is two days of the SUE Influence Framework applied to your own case. By the end, you have a structured way of reading what is actually driving behaviour, identifying the leverage points, and designing interventions that work because they fit how decisions actually get made.
Maximum 16 participants. Live with a SUE trainer.

Why free things feel less valuable
Behavioural economist Dan Ariely ran an experiment in which he offered people a choice between a Lindt truffle for fifteen cents and a Hershey Kiss for one cent. Most people chose the truffle. When he dropped both prices by one cent, making the Kiss free, the majority switched to the Kiss, even though the relative difference between the two was identical.
The finding reveals something important about how zero affects decision making. Free does not feel like a very low price. It feels like a different category entirely. The risk of disappointment disappears. But so does the signal of value.
This matters for anyone offering free trials, freemium products, or complimentary services. What you give away for free will often be used less carefully, appreciated less, and cancelled more easily than something people have paid for, even a small amount. The act of paying creates commitment and attention that free never generates.
The implication is not that you should never offer things for free. It is that you should be deliberate about what free communicates. Sometimes a small price is not a barrier to adoption. It is the thing that makes adoption meaningful.
Here's to the stubborn optimists, who unlock the power of Behavioural Design for optimising work, life, and everything in between.
Until next week,
