Exactly. When it comes to depression the chemical imbalance theory comes from Zoloft. It is a drug that accidentally had the side effect of reducing depression in some patients. Curious scientists wanted to figure out why, so they examined it. Turns out Zoloft boosts serotonin in the brain. This created the chemical imbalance theory, but since then study after study for decades has disproved this, yet for some sort of reason the theory stays in the mainstream. Ibuprofen can cause an ulcer. Imagine some primitive ape sees this blood loss and assumes the blood loss is what reduces inflammation. The Zoloft serotonin study follows the same faulty logic.
