Trust & evidence

Evidence before authority. CultureTechLens publishes its methods, its limits, and its corrections alongside its findings. Claims carry grades — VERIFIED, SUPPORTED, PROVISIONAL, DISPUTED, UNRESOLVED — and unknowns are never reported as zero.

Every claim graded. Every source named. Every correction public — none to date.
