Drug action retrofitted into disease theory
The logic ran backward from treatment to cause. The resulting 'chemical imbalance' story was then amplified by pharmaceutical marketing well beyond what the evidence supported.

Recurring cycles of biological overpromise
American psychiatry has repeatedly swung toward biology: first nineteenth-century brain anatomy, then late-twentieth-century neurochemistry and genomics. Each time it promised imminent discovery of the organic roots of mental illness, and each time it underdelivered. The failures of each biological wave created the opening for rival paradigms such as psychoanalysis and social psychiatry. Reading the field as cycles of hype, disappointment and paradigm replacement explains its lurches better than a story of steady scientific progress.
The 1980 DSM-III coup against psychoanalysis
It replaced psychoanalytic, cause-based categories with symptom checklists, promising reliable diagnosis and remaining officially agnostic about etiology. This reshaped psychiatry around categorical disorders suited to drug trials and insurance billing. It also sidelined Freudian psychiatry, though biological causes for the new categories never materialized.
Deinstitutionalization failed through politics, not only drugs
The promised community care was never adequately funded. Many severely ill patients ended up homeless or in jails, showing how a new treatment can serve as cover for policy decisions made on other grounds.
