One of the biggest mistakes in UX? Designing based on assumptions rather than real user behaviour.
It’s easy to think, “This makes sense to me, so it must make sense to everyone.” But here’s the thing, you are not your user.
🚨 Common traps designers fall into:
❌ Using jargon because you understand it
❌ Assuming users take the “ideal” journey through an interface
❌ Prioritising aesthetics over functionality
❌ Being too close to a product (you know what happens next)
💡 Actionable tip
Test with real users early and often, run sessions where you can watch how they interact.
Watch where they struggle (without leading them)
Ask open-ended questions like “What do you expect this button to do?”
Be ready to scrap your brilliant idea if it doesn’t serve the user.
Look for the non-verbal indicators, long hovers over a section, pressing on something that has no action, etc.
Understand that the buyer isn’t necessarily the user. What works for marketing, doesn’t always work for your users.
If you don’t have access to real users, test with people who don’t know the product or use heatmaps – https://clarity.microsoft.com is free and pretty easy to use.
Great UX isn’t about what you think works—it’s about what actually works for the people using it.
Designed for Humans is here to make your UX resonate and work for real humans.

There's something quietly radical about standing in a gallery full of Lowry originals whilst wearing a shirt covered in the very same matchstick figures staring back at you from the walls. Art, conversation, impeccable shirts, and a few things about Lowry himself that most people never know.
TEDx Manchester 2026 at the Bridgewater Hall — seven hours, ten speakers, one very large stage. Here are the five talks that landed hardest, and what they mean for how we work, think, and pay attention.
We talked about big things. Some of us gestured a lot. And apparently I said something about glitter and turds that made it into the official Natter write-up, which feels like a personal milestone. Here's what actually came out of it.
As the year wraps up, we wanted to say a big, genuine thank you for all your support. Whether you have worked with us, cheered us on, challenged our thinking or simply believed in what we are building, thank you for being part of our story so far.
Gemini 3 can speed up UX and UI design without losing quality. This practical guide shows five ways to use it: wireframing, design system tokens and variables, UI to code, consistent visuals, and quick accessibility audits. Copy the prompts, ship useful artefacts, and stay inclusive.
Power up Figma Make with prompts that read like a brief, frames that act like systems, and tight constraints. Use the 10 minute Make loop, Prompt DNA and a token bridge to keep prototypes fast, accessible and on brand. Less rework, sharper demos, more time for human craft.
Most “intuitive” interfaces are just clear. This article shows how to remove cognitive load with precise language, predictable structure, and visible feedback. Use the clarity trifecta and the 3–30 ladder, run the five-second test, and fix mobile-first friction that costs sign-ups and sales.
Tailwind and Shadcn help designers and engineers move from ideas to accessible, consistent interfaces at speed, especially in an AI workflow.
