All psychiatric drugging is a hypothetical experiment because psychiatric diagnoses are based on subjective social observations rather than biological pathology[1]. However the psychiatric/pharmaceutical establishment still assumes biological causes even though they have no real proof. The mind is a metaphysical concept which no one understands, and yet many stand to profit on this fact by making popular but unsubstantiated assumptions.
Mixing multiple psychiatric drugs further compounds the issue, because when the companies selling these drugs are conducting their trials, they don't do so in conjunction with the myriad of other drugs that are usually prescribed to those with mental illnesses.
