In a Massachusetts lab in 2008, Dan Ariely strapped subjects to a device that delivered controlled electric shocks. Then he gave them pain relief. The pills were placebos, identical sugar pills wearing different price tags. Subjects who took the cheap pill, labelled at 10 cents, reported a 61% reduction in pain. Subjects who took the expensive pill, labelled at $2.50, reported 85%. Same pill. The price changed the body, not just the bill.

Of the four Ps in the marketing mix, pricing is the most powerful and the most ignored.

The forgotten P

Product, price, place, promotion. Three of those generate cost. One of them generates revenue. Yet pricing consistently gets the least attention. Most marketing departments pour their time into brand campaigns, channel strategy, and product development. Price gets handed to finance, or set once and never revisited.

A few reasons it gets overlooked. It feels like someone else’s job. Talking about money feels transactional. Pricing is the fastest lever a brand has, and somehow that speed makes it feel less strategic, when it is one of the most strategic decisions a brand will make.

There is also a paradox in how pricing is handled. Of the four Ps, it is by some distance the most flexible. A price can change in minutes: no agency brief, no production timeline, no media buy. Yet most businesses treat it as the most fixed element of all. Distribution channels take years to build. Product development cycles are long. Promotional campaigns need planning. The price could move tomorrow. The fact that most businesses never move it suggests how uncomfortable the conversation is.

Price changes what the customer feels

The Ariely study is not an isolated curiosity. The same year, a team at Caltech and Stanford ran a similar experiment with wine. Twenty subjects tasted five Cabernet Sauvignons inside an fMRI scanner. They were told the prices: $5, $10, $35, $45, and $90. What they were not told is that two of the five were repeats. The “$5” wine and the “$45” wine were the same. The “$10” wine and the “$90” wine were the same.

Subjects rated the higher-priced versions as tasting noticeably better. The brain confirmed it. Activity in the medial orbitofrontal cortex, the part of the brain that registers experienced pleasantness, was reliably higher when subjects thought the wine was more expensive. The brain itself was generating more pleasure, not just the mouth reporting it.

The implication is uncomfortable for any business that defaults to discounting when sales soften. A lower price tells the customer’s brain to expect less, and the brain delivers. Before cutting price, ask whether you are also willing to cut the perceived experience.

Anchoring works on everyone

The first number in the room sets the tone for the conversation.

A fence builder we called for a quote on a section of fence began by pricing the whole property, before being asked to. From that moment on, every smaller number felt reasonable by comparison. The tradie probably could not name the bias, but the technique was textbook.

Blair Enns, the man who teaches anchoring to creative firms around the world, tells the story of walking into a suit shop, being shown a $6,500 suit first, and walking out having spent more than he had planned to. Even knowing the technique did not protect him from it.

In a 1989 mock-jury study, John Malouff and Nicola Schutte found that jurors who were told the plaintiff demanded $100,000 awarded an average of $90,333. Jurors told the demand was $700,000 awarded $421,538. Same case, same evidence. The line tracks the number being asked for, not the facts.

Lawyers used to believe in a “boomerang effect”: ask for too much and the jury punishes you. In 1996, Gretchen Chapman and Brian Bornstein went looking for it. They ran an ovarian cancer case past mock jurors with four demand levels, including a deliberately absurd $1 billion. The boomerang did not show up. The $1 billion demand still produced a higher average award than the $5 million one. The title of their paper says it all: The More You Ask For, the More You Get.

Anchoring is automatic. Knowing the trick does not switch it off.

Choose your competitor

Customers do not evaluate prices in isolation. They compare. The question is: compared to what?

Nespresso pods cost roughly 35 pence each. By the kilo, that is five times the price of supermarket coffee. By the cup, it is a fifth of the price of a cafe latte. Nespresso made the strategic choice to be sold by the cup. Same product, completely different story.

Aesop sells a 500ml bottle of hand wash for $40 to $50. Palmolive sells one for $4. Aesop wins because it refuses to compete on the supermarket shelf. It places itself next to fragrance and skincare, in dimly lit boutique stores, with packaging that looks more like a cosmetic than a soap. The comparison set is small luxury, not other hand soap.

Most brands never make this call. They let the market decide who they sit next to, which usually means losing on price.

The fairness floor

Pricing power is real, but customers enforce a ceiling on it. In a long-running study, Daniel Kahneman, Jack Knetsch, and Richard Thaler asked members of the public to judge the fairness of various pricing decisions. A hardware store raising the price of snow shovels the morning after a snowstorm: 82% said unfair. A football team auctioning the last available tickets to a big game: 74% unfair. A grocer raising the price of a scarce variety of apple by 25%: 63% unfair.

The pattern is clear. Customers tolerate price rises that appear to be a fair response to costs, demand, or context. They turn on brands the moment a price rise looks like a profit at their expense. The principle Kahneman and his colleagues distilled was simple: don’t increase your profit at my expense.

For a brand, this means anchoring, comparison-set strategies, and decoy pricing all need to land on the right side of the fairness line. Get it right and you build pricing power that lasts. Get it wrong and you train customers to stop trusting you.

Pricing is a brand decision

Anchoring, comparison sets, framing, and perception are all controlled by environment, language, and ritual. The menu’s look, the photo on the proposal, and the shop where the product is sold. These are the things a brand exists to manage.

Treating pricing as a finance decision hands the most powerful brand lever to the wrong department. The number itself is the easy bit. The rest, the staging, the comparison, the language around it, is brand work.

Brand-led pricing decisions look different from finance-led ones. They start with the question of how the customer should feel about the number, not how the number was calculated. They consider what the customer will compare it against, and whether that comparison can be moved. They build the staging that makes the price feel inevitable: the right shop, the right photography, the right language, the right adjacent products. Almost none of that costs anything beyond attention.

Pricing is the most powerful number a brand will set. It is also the one most brands set last.
