What Huber, Payne and Puto found
In the early 1980s, Huber, Payne and Puto showed something that surprised economists. When people chose between two options, adding a third that was clearly worse than one of them, an asymmetrically dominated decoy, increased the share choosing the option it was inferior to.
Nobody picks the decoy. It works by making the comparison easy. Instead of weighing two different trade-offs, the buyer sees one option that is simply better than another, and that clear win feels safe. That is why the effect shows up in layouts with exactly three packages, and why web design that sets them in clean, even columns matters.
How a three-package layout works
Say an Abbotsford HVAC company offers furnace care. A basic visit covers a filter and a safety check. A standard visit adds a full cleaning and a written report. A premium visit adds priority booking and a mid-season check. On an online store the same logic applies to product bundles. Most households see the middle one as the sensible pick, and some choose the top for the peace of mind.
The middle package is not a decoy here, since it is the one the company wants and also suits most homes. The basic package gives people a cheap way in and a point of comparison. The premium one has its own buyers. Each tier answers a real need, which keeps the layout honest.
Setting out the packages on the page
Layout carries a lot of weight. Put the three packages side by side with the same rows in the same order, so the differences are easy to scan. Mark the one you suggest with a plain label like most booked, which is a quiet form of social proof, only if that is true. Use the same plain wording for every tier.
Anchoring can matter too, since a high first number pulls later judgements towards it, but that is a topic of its own and is covered in our guide to pricing psychology. Here the focus is the structure: three tiers, clear rows, and one call to action per tier. Avoid a wall of fine print under the buttons.
When a decoy is honest and when it is a trick
A decoy is a trick when no sensible buyer would ever choose it. Imagine a package that costs almost as much as the next tier but includes half as much, put there only to push people up. That is a nudge built on confusion, and customers who notice will remember it.
A fair test is simple. Could you comfortably explain to a customer why each package exists and who it suits? If a tier exists only to make another look good, remove it or improve it until it has a real buyer. A label that claims popularity it does not have drifts into false urgency or worse. Honest layouts last, and they keep your reputation intact when word travels in a small valley town.
Testing a layout without fooling yourself
The original studies were controlled experiments, and your website is not. Seasons, ads and word of mouth change who arrives. Run a test long enough to see a pattern, change only the packages, and compare the share choosing each tier. The conversion rate calculator on this site helps you judge what a shift in sales would be worth.
Look beyond clicks. If more people choose the middle package but cancellations or complaints rise, the layout is promising something the service does not deliver. A good package page sets expectations clearly, so the work that follows feels like what was offered. The growth check can also show whether pricing is where you lose people or whether the leak is elsewhere.
- Write who each package is for in one plain sentence
- Line up the rows so every tier is compared on the same points
- Label a recommended tier only if it really is the most chosen
- Remove any tier that no sensible buyer would pick
- Review sales by tier each quarter and adjust
Keep packages simple as you plan for 2027
As online stores add more options and automated quotes, it will be tempting to add tiers. Resist that. Three clear packages are easier to understand, easier to explain on the phone and easier to test. Treat 2027 as a time to prune, not to add, and keep every tier tied to a real customer type.
- 01Review each package against the customers who actually buy it
- 02Merge or drop tiers that overlap
- 03Keep your phone and web descriptions of each package identical
Questions & answers
It is the finding that adding an option clearly worse than one existing choice makes more people pick that existing choice. The weaker option gives the buyer an easy comparison, so the better one feels like a clear win.
A layout with real packages is ordinary pricing design. A tier built to mislead, or a claim like most popular that is not true, can breach Canada's Competition Act, which prohibits false or misleading representations. Keep every tier honest and every label true.
Three is a common and workable number because it is easy to compare. Offer fewer if your service is simple. More choices can make people hesitate, so only add a tier when a real customer group needs it.
No. The studies were controlled experiments, and real shoppers vary. The effect depends on how easy the comparison is and on how clear the differences look. Test your own layout and watch outcomes beyond the first click.
