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 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 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.
