Most designers call familiar things "intuitive" and stop there. The actual goal is harder: design interactions that mirror the real world so well that nothing needs to be learned at all.
"Intuitive" is a misused word in UX.
Nothing is intuitive — except when it actually is. And the difference between those two cases tells you everything about how to design well.
The real world already trained them. The interface just didn't break the rule. That's when intuition is actually real — when a micro-interaction maps to physical reality so cleanly that the hand knows what to do before the brain catches up.
A volume slider is different. Nobody explains it. You move it left, sound drops — because it mirrors a physical dial you've turned your whole life. Same with scroll: you push content up with your finger because that's exactly what you'd do with a piece of paper on a desk.
Kids today have never held a floppy disk. But they know that icon means "save." That's not intuition — that's learned behavior. Familiar, not intuitive.
One question before you ship any trigger:
Is this serving what the user is trying to do — or what the product is trying to get them to do?
Most teams have never asked. Start there — and cut every trigger that can't answer honestly.
Notifications are the biggest UX failure of the last decade.
We didn't design for communication. We designed for interruption — then called it engagement.
