You have a trick looking for a page. Len P. van der HofPublished 17 September 20263 min read Same object. Different experience. The number is not the whole event. Direct answer Pricing psychology is the study and design of how a buyer experiences a price, not the price as a naked number. On this site the named system is PRICE: Perceive, Reference, Irrational, Context, Endow. Perception is what the number is seen against. Reference is the comparison the buyer actually uses. Irrational names the systematic biases you refuse to pretend are noise. Context is the frame around the offer. Endow is anticipated ownership: how it feels to have it versus not. It is not a playbook for hiding fees or nudging a tired checkout. A conversion system that stays honest is the neighbouring operating note. The Pricing Mind owns the expansion and is in production, not for sale. This page is the meaning, including the Dutch query prijspsychologie. ## Key takeaways - A price is experienced. The naked number is not the whole event. - PRICE = Perceive, Reference, Irrational, Context, Endow. Five names, not a trick list. - Honesty is a constraint, not a vibe. Hidden fees are not psychology. - This page is the meaning. The book is in production. The honest-conversion article stays next door. People search “pricing psychology” after a deck promised that a different number would “feel cheaper.” Sometimes the number should change. Often the room is arguing about a trick. **What is pricing psychology?** How a buyer experiences a price. Not the price as a naked number. The comparison, the frame, the bias you refuse to pretend is noise, and how it feels to have the thing versus not. On this site the named system is PRICE: Perceive, Reference, Irrational, Context, Endow. [The Pricing Mind](https://lenvanderhof.com/books/the-pricing-mind/) owns the expansion. The book is in production and not for sale. This page is the meaning. ## Five names, not a trick list **Perceive.** The number is seen against something: a previous plan, a competitor, last year’s invoice, a round number on a menu. If you do not know what it is seen against, you are decorating. **Reference.** The comparison the buyer actually uses is often not the one on your slide. Write the real reference down, or you will “win” a comparison nobody runs. **Irrational.** Systematic biases are part of the event. Naming them is not a licence to farm them. If the design only works when the buyer is tired, it is not psychology you should ship. **Context.** What sits around the offer: timing, bundling, who is in the room, what happens if they wait. Context is a decision, not wallpaper. **Endow.** Ownership and anticipated ownership. Instant endowment for a held object is a mixed finding, not a SaaS law. A genuinely used trial may create something the buyer would feel they lose. A default, a countdown, or a card on file does not manufacture endowment. Loss-framed copy is a separate mechanism. If you cannot point at which of the five you are changing, you are not doing pricing psychology. You are moving a digit. ## Collision control **Not a dark pattern.** Hidden fees, a countdown that is not a countdown, a pre-ticked add-on. That is a conversion system that failed the honesty test. [A conversion system that stays honest](https://lenvanderhof.com/en/blog/conversion-systems-that-stay-honest/) is that operating note. **Not “charge more.”** A higher price needs a value and commercial case. Psychology can explain how buyers interpret the change. It does not justify the number. **Not a literature review.** Kahneman and Cialdini are not this page. Naming a bias is not the same as designing the moment a buyer meets a number. ## What this page is not It is not a PRICE audit worksheet. It is not a checkout redesign. It is not a promise that five letters will raise conversion. Write which of the five you are changing, and what the buyer will see. If the only honest sentence is “we hope they do not look,” stop calling it psychology. ## Sources 1. [The Pricing Mind](https://lenvanderhof.com/books/the-pricing-mind/) 2.
