Most science outside of physics is politically motivated statistical manipulation and physics is not 100% immune either. Physics is the king of the sciences and math is the Queen-- Psychiatry is clown world. Aristotle's natural philosophy turned into physics but Plato's philosophy of the mind is not tangible --the wall of the mind is intangible and metaphysical. Since, physics is the king of the sciences all sciences must obey its laws but to say psychiatric nosology obeys the laws of physics is nonsensical and obviously not true. If a 'disease" in the DSM were found to exist it would move to neurology.

Why Most Published Research Findings are False :

"In the paper, Ioannidis argued that a large number, if not the majority, of published medical research papers contain results that cannot be replicated. In simple terms, the essay states that scientists use hypothesis testing to determine whether scientific discoveries are significant. "Significance" is formalized in terms of probability, and one formalized calculation ("P value") is reported in the scientific literature as a screening mechanism. Ioannidis posited assumptions about the way people perform and report these tests; then he constructed a statistical model which indicates that most published findings are false positive results."

It is impossible for true science to exist under Capitalism.

Karl Marx's theory of historical materialism states that the source of human progress and historical change is not to be found in “legal relations” or “political forms,” but rather “in the material conditions of life”. By this Marx means that the economic relations of human beings determine all other relations in that society. Material survival rather than the development of rationality and spiritual thinking forms the fundamental basis of human endeavour in each historical epoch. Since, the development of rationality is sorely lacking in Capitalist society real science does not exist or is in the minority and contained largely to physics.

Psychiatry is an ISA ( Ideological State Apparatus) in Capitalist society. It masquerades as a branch of medicine and a science so that its propositions seem like neutral and objective discourse that is detached from elite control by that is far from the truth
