Prototype Quality Matters (Often Ignored)
Do not test experiences users cannot realistically perform — you'll only manufacture false confidence.
Testing with click-through prototypes, unrealistic interactions, or non-functional inputs invalidates results, masks real friction, and creates false confidence. Guiding or helping confused participants destroys research integrity just as surely.
A usability test is only as honest as its prototype. Test something users cannot realistically perform and you get results that look like validation but measure nothing.
- Click-through prototypes that skip real interaction
- Unrealistic interactions that don't match the shipped product
- Non-functional inputs that hide entry friction
- Guiding participants through tasks
- Helping confused users mid-test
Each of these masks real friction and manufactures false confidence. The rule: do not test experiences users cannot realistically perform, and never rescue a struggling participant — their struggle is the data.
Apply this
Reading about prototype quality matters (often ignored) is one thing. Seeing where it applies in your journey is the useful part.
