This work ships as an interactive instrument, not a text — it has no README to mirror. Use it live in the lab (link above); its data and metadata live in the original repository.
The Digit Mirror
Four datasets enter the last-digit uniformity test; three exit as suspects for entirely different reasons — clinical rounding, cultural age heaping, and genuine fabrication. Panels B and C are mirror images: one peaks at 0 and 5 (human rounding preference), the other dips at 0 and 5 (human fraud avoidance). The test cannot tell the difference.
