The Builder's Dispatch

84% of readers scan, not read. Eye-tracking research shows structure matters more than style. Only 16% read word by word. The rest sweep the top, sweep again, then scan down the left edge looking for hooks. Working memory holds around four chunks at once. Beyond that, comprehension drops fast. That changes how technical documentation should be written: -> front-load the point -> optimize the left edge -> keep lists tight -> use headings as mental bookmarks Good documentation is not about writing more. It is about cognitive efficiency. Write for scanners first. Readers can still read.
