# Mapping — cultural (convention and signaling)

Cultural mapping carries meaning through shared convention. The user knows the gear means "settings" because they've seen it a thousand times before. They know red means stop, green means go, yellow means slow. They know the trash can means delete and the magnifying glass means search. None of these mappings is innate — they all had to be learned somewhere — but within a culture that recognizes them, they're effectively free.

Cultural mapping is the workhorse of icon-driven interfaces, because the spatial form of mapping is rarely available for software UI. You can't physically place a "settings" control next to "the settings"; settings are abstract. So you reach for a metaphor — a gear, a wrench, a sliders icon — and rely on the user's prior exposure to interpret it.

## When cultural mapping works

A cultural mapping works when three conditions are met.

**The convention is genuinely universal in your audience.** A red stop sign is universal in driving cultures. A floppy disk for "save" is recognizable to most adults in industrialized cultures, though weakening as a generation that never used floppies grows up. A mortarboard hat for "education" is universal in cultures with that academic tradition.

**The convention is the dominant convention, not one of several.** A magnifying glass for "search" is dominant. A gear for "settings" is dominant. But a globe icon could mean "internet," "international," "translation," or "external link" — none of those is the dominant interpretation, so the icon needs a label. When two conventions compete, you need disambiguation.
