Fly-Eye Effect

At a busy airport, someone etched a small image of a fly into the men's urinals. Spillage dropped by most of its former self. No signs, no rules, no fines — just a tiny target, and attention did the rest.

The principle: attention goes where it is given something to aim at. A small, vivid detail focuses behaviour more reliably than a large, earnest instruction. People do not follow priorities; they follow targets.

Every designer of anything — forms, shops, meetings, kitchens — wields this whether they know it or not. The thing placed at eye level is chosen; the first item on the agenda is discussed longest; the number shown first anchors the negotiation.

So paint your flies deliberately. Want to read more? The open book on the pillow, not the resolution in the journal. Want the meeting to decide? Put the decision on the first line. Small visible targets beat large invisible intentions, every single time.
