Psychology

The Psychology of Two Equal-Priced Options

Decision paralysis: two items, identical prices, different perceived value.

Three Subconscious Questions

1

Am I a value-maximizer
or health-conscious?

2

Is this a good deal?

3

What will people behind me
in line think?

"

Adding one button introduced measurable cognitive burden that did not exist before.

Key Insight

Before: 0 decisions · After: 1 decision + identity evaluation

What Works

Three things the kiosk UI gets right.

Large Touch Targets

Accessible for users across multiple generations — from seniors to digital natives.

Accessibility
WCAG

Frictionless Payment

Credit card tap, no loyalty numbers, no tip screen — zero unnecessary steps.

NFC Tap
No Friction

Fitts' Law Optimized

Frequently used items placed near payment buttons — minimizing travel distance.

What Needs Fixing

Three UX failures introduced by the change.

No Value Explanation

Buttons don't explain the trade-off: soda = larger + refills, water = bottled + portable.

No Visual Hierarchy

Both options appear as equals with no guidance toward the higher-value choice.

Membership Friction

New card-scan requirement adds a screen between the hungry user and their food.

Choose Item
⚠ Scan Card
Pay
Get Food

The pattern: Every fix adds context, hierarchy, or removes steps from the critical path.

Principles

Four UI/UX Principles to Steal

Universal lessons from a $1.50 hot dog.

01

Every Option Has a Cognitive Cost

Before adding a feature, ask if the freedom is worth the mental load.

02

Identical Pricing Creates Value Confusion

Label items explicitly — "Best Value," "Most Popular."

03

The Default Is the Design

Pre-select what 80% of your users want; let the minority opt out.

04

Nostalgia Is a UX Force Multiplier

Before redesigning anything stable, understand its emotional role in users' lives.

Quick Audit

The 3-Column Quick-Audit

Run this checklist on any product with option complexity.

Element What to Look For The Fix
Equal-priced options Different value for same cost Add "Best Value" badge or microcopy
No default selected User must actively choose Pre-select the majority option
Missing context User guessing what each option includes One line of supporting text
Login gate in flow Verification step before checkout Place before customization, not after
Feature creep (tap count) Total taps increased in last year Quarterly walkthrough audit

Big Picture

The Bigger Costco Picture

Early 2026 Changes

Pepsi → Coca-Cola Switch

Reversing the 2013 decision. Kiosks updated across all locations.

Caramel Churro Sundae

New seasonal item with mixed reviews — added to kiosk menu.

Membership Verification

Cards now required for food court purchases — new kiosk step.

All changes connect through digital kiosks

The primary touchpoint for millions of weekly customer interactions.

Final Word
The 25-Cent Question

The cost difference that changes everything about how users perceive value.

The Flicker

That split-second pause between two nearly identical options —
that is where UI/UX design lives.

"

Designer's Mandate

Am I adding a button that helps, or one that makes users choose between being smart and being healthy?

Answer that, and you are already ahead.
