Four UX Heuristics That Cover Most of What Product Builders Get Wrong
Watch on TikTok
If you only carry four UX rules into a build, make them these: show users where they are, make the interface look good, never depend on user memory, and copy patterns that already work. In this 48-second talking-head video, the creator behind Zen UX Design delivers a compressed checklist for anyone designing or building a digital product. The advice sounds simple, but each point maps to established usability research, and each one is a common failure point in apps built by engineers moving fast without a designer in the room.
Show People Where They Are
The first heuristic is visibility of system status. The creator frames it in two parts: always show the user where they are in the grand scheme of things, and make sure they can always get back to where they were. This is the first of Jakob Nielsen's ten usability heuristics, and it covers everything from breadcrumbs and progress indicators to loading states and confirmation messages. The failure mode is an app where users tap into a flow, lose track of their position, and cannot find a safe way back. Orientation and reversibility are the baseline for user trust.
Looks Are Not Cosmetic
Second is the aesthetic-usability effect. As the on-screen captions put it, the better looking something is, the more people will perceive it to work well. The creator calls this "a given" and his advice is blunt: make it look really good and make it match your brand, and you will have good results. The research behind this goes back to a 1995 study by Masaaki Kurosu and Kaori Kashimura, who found users rated attractive ATM interfaces as more usable even when the underlying functionality was identical. Polish buys you forgiveness. Users tolerate minor friction in a product that looks credible and abandon the same friction in one that looks rough.
Never Rely on the User's Memory
The third heuristic is the most practical: do not rely on the user's memory. Always surface information that may be relevant to them, because, as the creator says, people's memory is actually pretty bad. This is Nielsen's recognition-over-recall principle. Concretely, it means showing previously entered data instead of asking for it again, keeping context visible across steps in a flow, and putting options on screen rather than expecting users to remember commands or codes. Every time a design asks a user to hold something in their head between screens, some percentage of them will fail.
Steal From Products That Already Did the Research
The last point is permission to borrow. Do not be afraid to emulate the best experiences out there, because those teams have already put in a ton of research and already know what people need and what they like. Large products have run thousands of usability tests and iterations on patterns like onboarding, checkout, and navigation. Deviating from those conventions means paying the research cost yourself. Familiar patterns also compound with the memory principle: users arrive already knowing how they work.
The Format Matches the Message
The delivery is worth noting. The entire video is a single selfie shot of the creator in a black t-shirt at his desk, with one persistent caption card reading "Basic UX Principles to know!" and live subtitles tracking his speech. No screen recordings, no slides, no product examples. The video practices its own second heuristic in miniature: clean framing, high-contrast captions, and a single visual anchor make a plain list feel authoritative. It is a checklist, not a lecture, and it is built to be replayed.
Key Takeaways
- Always show users where they are in the app and give them a clear path back to where they were.
- Attractive interfaces are perceived as more usable, so invest in visual polish and brand consistency.
- Design for recognition, not recall. Surface relevant information instead of expecting users to remember it.
- Emulate proven patterns from best-in-class products rather than reinventing flows they have already researched.
- These four points condense well-documented usability research into a checklist you can apply on any build.
