What is it really that psychology studies and how is it even possible to study that “matter”? What is “agency of sentient cognition” and how is it even possible that “agents of sentient cognition” may meaningfully interact with each other even when belonging to quite different species?
Brain research addresses the various scientific aspects of the workings of the brain including electrical reactions, yet how is it possible that brains are able to mutually interact with each other even without speech? Communication has generally been anthropocentrically taken for granted without any demands for proving that communication actually is possible. We know that it is possible, yet we need also endeavor to understand what communication is in terms of natural science and indeed how it is even possible. Once we know “how it is done” will we be able to devise advanced technologies that will enhance interpersonal communication even further including ethico-politically importantly so with agents of sentient cognition of non-human species.
Since we know that communication within the brain takes place by means electrical reactions should we assume that something similar takes place in communication between agents of sentient cognition. From an epistemological perspective is thus psychology generally all parapsychology as far as interpersonal communication is concerned. Many human problems are derived from deficient communication and so in order to enhance the quality of interpersonal communication need we first rigorously discover how it actually takes place.
Communication IRL is rich and multidimensional and odors (i.e. chemical and hormonal factors) make up a large proportion of communication between sentient agents of cognition IRL. Communication is furthermore sentient, meaning neurological and so there is every reason to assume that there is inter-neurological interaction between agents of sentient cognition even when not in physical contact. What is after all the state of falling in love but neurological contact? Another question relates to how this is even possible across great distances. How is it e.g. even possible for a person in New Zealand to neurologically fall in love with a person in Canada despite the great geographical distance between the two? In fact, falling in love with an already dead or non-existent, fictional person is completely unheard of. No one ever fell in love with Donald Duck. Physicists recognize that they know almost nothing about the realm of physics and so it is no wonder that academia is fully unaware as to how emotional (i.e. neurological) contact is possible across great distances.
While psychology is almost an exact science needs psychology be given solid foundation in genetics and physics alike. Psychology at present is epistemologically speaking essentially unproven tautology which is not to imply that psychology lacks foundation but rather that psychology needs become a proper strict science in being grounded in detailed understanding of the natural science underlying the existence of agency of sentient cognition.
The question of subconscious communication offers a perfect case indeed for the study by physics of how communication between sentient agents of cognition actually is performed. Introjection/projection is how subconscious communication is usually described, yet these terms however valid and well-founded nevertheless lack foundation in natural science and so what is needed is rapprochement and collaboration between physicists and psychologists in understanding the natural science of subconscious communication and in particular so in terms of physics. Indeed, this is not much different from other aspects of psychology which typically also lack solid foundation in natural science.
The field of psychology thus very much needs become reinvented as an exact natural science in connecting psychology with other exact sciences indeed.
