Urban dwellers must code strangers accurately using only visual information.

Evidence

Human beings, if they are to act at all, must define. And if they are to avoid hurts to their fragile selves, they must define with a relatively high degree of accuracy. Yet all the city dweller had to go on, to know anything at all about these other people, was the information he could glean by looking at them. — Lyn H. Lofland, World of Strangers_ Order and Action in…, 131

• XREF: Directly adjacent to the reader’s framing: city dwellers code strangers visually without interpersonal trust — the cost of accurate-but-impersonal perception is the blasé detachment Cole describes.
• DEEPTHINKING: The paradox at the book’s core, stated in embryo: accurate self-protection demands high-accuracy definition, yet the urban coder is reduced to appearances — accuracy grounded in the thinnest possible evidence.
