We only act on what we notice.
The rest? Ignored. Forgotten. Gone.
A cue can whisper or shout.
Too quiet, and behaviour never starts.
Too loud, and it’s seen as noise. It's skipped, swiped, or shut down.
Think:


What to do
What you’ll notice
- Users say “Oh, I didn’t see that.”
- Key features sit untouched
- Uptake spikes only after you point the cue out in person
Why it happens
Low-salience prompts blend into the scroll noise, so our brains auto-filter them out.
Select a strategy to reveal tactics:
What you’ll notice
- Users dismiss or close the prompt instantly
- “Feels spammy” feedback
- Important content buried under visual noise
Why it happens
Over-powerful cues annoy users and crowd out the task they came to do.

Why it matters
All behaviour starts with a trigger.
The gun at the start of the race.
A ping on your phone.
That sudden “I’m starving” moment.
All make you pause, perk up, and say:
“Oh, time to move.”
That’s why cues matter. They start the behaviour.
But, it's hard to get them right:
- Attention is scarce. Your cue competes with 1,000 others every minute.
- Signals guide action. If the call-to-act hides in plain sight, behaviour never gets on the runway.
- But volume cuts both ways. Over-loud cues feel spammy, trigger skip-behaviour, or worse, user irritation.
- People get used to things. What once stood out fades into background noise.
Cue Visibility isn’t just about colour or size.
It’s timing, placement, contrast, and relevance.
The science bit
Fogg Behaviour Model (B = MAP)
Behaviour only happens when motivation, ability, and a prompt meet at the same moment. If the cue’s not seen (or comes too early/late), nothing happens.
→ Prompts need timing and clarity to work.
MINDSPACE: Salience Principle
We act on what stands out. Novel, vivid, personally relevant cues get noticed. Bland ones fade into the noise.
→ Visibility isn't just design, it's psychology.
Banner Blindness
When cues look like ads, people skip them... even if they’re useful. Loud doesn’t mean seen.
→ If it screams, we ignore it.
Inattentional Blindness (The Invisible Gorilla)
If someone’s focused elsewhere, they’ll miss even the obvious. It’s not about eyesight, it’s about attention.
→ Cues fail when they fight attention, not grab it.
