Every specimen here is a real, published chart — from a newsroom, a government agency, or a landmark book on statistics, not invented for the lesson. Sources are cited at the bottom of each plate so you can check the checking.
Field Guides No. 1 and No. 2 covered how claims get framed, spread, and misinterpreted. This edition zooms in on the picture itself — the axis, the scale, the icon — since a chart can distort a true number without a single fact being wrong.
This guide covers four specimens; Field Guide No. 1 covers twelve patterns in how false claims get framed and spread, and No. 2 covers eight more in how accurate data gets misread. The Incognati Atlas catalogs thousands more — biases, fallacies, distortions, and manipulation patterns, each one documented the same way: real case, real source, real tell.
