Design is not about teaching. It's about feeling at home
Users arrive with mental models already formed — built from years of dustbins, shopping carts, and landline phones. The designer's job isn't to teach them something new. It's to meet them where they already are.
Design for users, not for yourself
This heuristic is about designing products that speak the user's language — visually, interactively, and in words. It's about aligning design with real-world behaviour, not internal team logic or technical conventions.
Our first responsibility is to understand who our users actually are. Not who we assume them to be.
"What is their tech comfort level? How do they interact with digital products? What do they expect based on their real-world experience? Assuming users will figure it out is never a good UX strategy."
— The core question this heuristic forces you to ask
Even senior professionals in decision-making roles might not be as comfortable with digital interfaces as we think. Clarity over cleverness — always. When we answer these questions honestly, choosing the right icons, words, and patterns becomes natural.
The recycle bin needed zero explanation
Let's take the simplest example: the Recycle Bin on a computer desktop. We've all seen it. We all instantly know what it means. But nobody taught us. No manual explained it. We just knew.
Because in the real world, we've used dustbins all our lives.
The digital system borrowed a mental model that already existed in the physical world.
The behaviour mapped perfectly — throw away what's not needed, retrieve it if you change your mind, lose it forever once the bin is emptied. The digital system borrowed a mental model that already existed.
Users didn't need a tutorial. They felt at home instantly — because the design respected what they already knew.
Intentional choices, not random icons
The recycle bin isn't an isolated example. Everywhere in digital design, real-world objects have been borrowed to make digital actions instantly understood.
These metaphors are not random. They are intentional choices that connect digital actions to real-world understanding — letting users recognise what to do instantly, without a tutorial.
It's not just icons — it's words too
This heuristic extends beyond visual metaphors. The language we use in a product matters just as much. When words on a screen match how users actually think and speak, everything feels natural. When they don't, users hesitate — even if the function itself is simple.
Clear language is inclusive language. It lowers the barrier for every user who isn't a developer, designer, or power user.
| Don't say | Say instead | Why it matters |
|---|---|---|
| Deploy | Publish | Most users understand "publish" from everyday life. "Deploy" is an engineering term that creates distance. |
| ETA | Expected by / Arrives in | Acronyms assume familiarity. A plain phrase removes the assumption entirely. |
| CX / NPS / CSAT | Customer experience / Satisfaction score | Internal business terms mean nothing to most users. Use words they'd actually use themselves. |
| Invalidate cache | Refresh / Clear saved data | Technical actions need plain-language descriptions. Users care about what happens, not how it works under the hood. |
Jargon in the first sentence tells the user: "This wasn't made for you."
All of this comes from one thing: empathy
Ultimately, this heuristic is about one thing — knowing your users well enough to design in their language, not yours. The better we understand their habits, mental models, and level of tech comfort, the easier it becomes to meet them where they already are.
"This heuristic is not just about making things familiar — it's about building trust through understanding. When a product speaks your language, it feels like it was made for you."
— The real goal of H2
Ask these before every design decision: How do users normally interact with products like this? What references do they already understand? What words do they use for this task? The answers should shape every label, icon, and interaction in your product.
Let them feel at home
When systems speak in a language users already understand, the product feels natural — like it was made just for them.
The recycle bin didn't need a manual. The shopping cart didn't need a tutorial. The phone icon didn't need an explanation. They all borrowed from a world users already knew — and that's exactly what made them work.
Design is not about teaching people something new. It's about letting them feel at home.
Apply this to your next design
Go through every label, icon, and CTA in your product. Ask: would a user who has never seen this before understand it immediately? If not — what real-world reference could you borrow to make it click?
