Build a Cognitive-Load Checkout Checklist
Objective: Build a reusable one-page checklist of the friction points most likely to wake System 2 during checkout, so any future redesign can be screened against it in minutes.
You're a CRO analyst at HelloFresh, the meal-kit subscription company, and the design team keeps proposing checkout changes with no shared standard for what counts as friction. You're building the checklist that becomes the standard.
Turn the lesson's cognitive-ease principle into a concrete, reusable checklist a designer could run through in under 5 minutes on any checkout page.
Before you start
What you'll need
Free path (everything below is enough to finish)
Free tier supports checkboxes and is easy to share with a design team
No access? Google Sheets works equally well if Notion access isn't available
The process
1 step
Step 01 of 01
The lesson names cognitive ease as the discipline of removing friction at the moment of action, every extra form field, unexpected fee, or jargon word wakes System 2 and gives it a reason to walk away.
What are the 8 most common friction points on a checkout flow that give System 2 a reason to stop and think, and how would you phrase each as a yes/no checklist item?
Procedure
- List every moment in a typical checkout where a customer might pause: form fields, price reveals, account creation, shipping cost, confirmation
- For each, write one yes/no checklist question a designer can answer just by looking at the page
- Group the 8 items under 3 headers: Before Checkout, During Checkout, At Confirmation
- Add a one-line 'why this matters' note under each item, referencing System 1/System 2
COGNITIVE-LOAD CHECKOUT CHECKLIST
BEFORE CHECKOUT
[ ] Is the total price (including shipping/tax) visible before the final screen?
Why: a surprise price at the end is the #1 System 2 trigger, per Baymard's 2024 abandonment research
[ ] Can the customer check out as a guest, without creating an account first?
Why: forced signup adds a decision point that has nothing to do with the purchase
DURING CHECKOUT
[ ] Are there 5 or fewer form fields on the payment step?
[ ] Is there any jargon (SKU, promo code terms, shipping tier names) left unexplained?
[ ] Does autofill work on every field?
AT CONFIRMATION
[ ] Does the confirmation screen restate exactly what was charged, with no new numbers?
[ ] Is the cancel/refund policy one click away, not buried in a footer link?
[ ] Is there a single, unambiguous next action (not 3 competing CTAs)?Healthy
The checklist has exactly one clear yes/no question per friction point, and a designer could run through all 8 items on a real page in under 5 minutes.
Unhealthy
Checklist items are vague opinions ('does it feel easy?') instead of yes/no, checkable facts about the page.
What this means
A checklist item that requires judgment instead of observation will get answered inconsistently by different people, the whole point of building the asset is to remove that inconsistency.
So what do I do about it?
| Symptom | Action | Effort |
|---|---|---|
| A checklist item can't be answered with a clear yes or no | Rewrite it as a specific, observable fact about the page | 5 min |
Final deliverable
A reusable 8-item cognitive-load checklist, grouped into 3 checkout stages, ready to run against any future checkout redesign.

Chewy checkout cognitive-load review, applied to the Autoship signup flow BEFORE CHECKOUT [x] Total price visible before final screen [x] Guest checkout available DURING CHECKOUT [ ] 5 or fewer form fields, FAIL: 8 fields on payment step, address autofill missing 2 fields [x] No unexplained jargon AT CONFIRMATION [x] Confirmation restates charge with no new numbers [ ] Cancel policy one click away, FAIL: buried in footer Result: 6/8, two flagged for the next sprint
Success criteria
You're done when you can:
- Produces exactly 8 checklist items, each phrased as a yes/no observable question
- Each item includes a one-line System 1/System 2 rationale
