It is absurd to imagine that the sort of things issues it deals with can be handled by science at all. To imagine otherwise is to not understand what actual science is about.

The fundamental human aspects and values it wishes to describe and “measure” ere not physical at all–they are fundamentally mental, moral and spiritual. They are best approached though philosophy (ethics and metaphysics), religion and, grasped tangentially and obscurely, the arts.

It is one thing to accurately predict the boiling point of water; it is quite another thing to put form certain beliefs, actions or world views as nominative absolutes. Science is valuable precisely because it limits its metaphysical aims. It does not attmpt to describe the meaning of water boiling in the human realm.
Psychologists are not possessed of this sort of humility (or, evidently, common sense, or breadth of education or culture)

The problem with “Physiological Research” is that it is not really research in any scientific sense at all–it should not be taken seriously at all in its current form. It is more like the sort of “research” a novelist of a screen-play author might make, which is to say it is mostly about shoring up fiction with some superficial reference to the external world and Man’s movement through it..
