Mapping the DSM-5 in Vector Space (And Why Psychiatric AI Is Chasing a Ghost)

As an engineer, I look at the world through the lens of data architecture, relational integrity, database schemas, and decision trees. If a system’s database has circular dependencies, porous boundaries, or redundant records, we call it a bad design and refactor it.

Yet, the most authoritative database of human suffering—the American Psychiatric Association’s DSM-5-TR (Diagnostic and Statistical Manual of Mental Disorders)—violates almost every principle of clean data architecture.
