What exactly is "Information Metabolism"?
"Information Metabolism" is a theory that Socionics apparently incorporates, and people throw this around as a vague and nebulous "scientific-y" thing, but what exactly is it?
It doesn't appear to have much if any scientific ground:
Is the theory of Information Metabolism a reasonable scientific theory?
Short answer: No.
A literature search of Google Scholar and Web of Science for "information metabolism" finds no empirical evidence to support the theory. Furthermore, it appears that the theory of information metabolism is virtually only embraced directly by the author, Kępiński, himself.
However: It is based on scientifically sound principles of dissipative systems, thermodynamics and negentropy, as proposed by Nobel prize-winning physicist Ilya Prigogene. In some sense, though, it is based on science in the same sense a movie may be based on a true story. It's not a triviallywrong theory, but there does not appear to be any concrete support.
CREATES and theories resembling information metabolism theory
CREATES does not appear to have any scientific basis or relation to information metabolism theory whatsoever. However, the link you provided cites Carnot’s principle as a basis for the theory of information metabolism:
“the organism is an open system and its negentropy rises or falls as results of processes described by the laws of life conservation and species conservation, respectively”
This is very similar to the principles of more modern embodied dynamical systems approaches to explaining behavior, such as the ecological psychology of Mace, Turvey and Shaw. Both ecological and information metabolic approaches appear to be epistemologically dynamicist, and therefore share an epistemological stance. They appear to differ strongly on the content theory of the cause of behavior (i.e., on what constitutes a meaningful scale for behavioral analysis): information metabolism theory draws more heavily on Freud and Jung, while ecological psychology draws on the work of James J. Gibson.
Concluding remarks
Information metabolism theory is not a reasonable scientific theory in 2015, but neither was it scientifically stillborn in 1970. It appears to have been a theory invented before its time; in this, it is also like Gibson, who similarly lacked both the theoretical and mathematical tools to specify and formalize ideas. The popularization of those tools in behavioral science would eventually lead to the development of ecological psychology as a full fledged school of thought in the decades after Gibson's death.
In the case of information metabolism theory, however, it appears that either the theory was entirely subsumed into socionics and therefore no longer exists as an independent theory, or simply that no one took up the mantle as the scientific star of psychoanalytic approaches rapidly waned around the same time.
Edit: There seems to have been some limited attempts to update the theory for modern dynamical systems tools around the turn of the millenium (Kokoszka, 1999; Kokoszka, Bielecki and Holas, 2001), but still nothing empirical to validate it.
