Stan Gooch (born in Lewisham, London, 1932) is a British psychologist and paranormal researcher who is probably best known as the proponent of the hybrid-origin theory.
Gooch's first book Total Man was an attempt to examine all fields of interest relevant to man today. On the back cover of the American print of Total Man Stan Gooch states:"Essentially, the view I have taken of other 'theories of personality', such as those of Marx, Christianity, Freud, Pavlov, Nietzsche and many others, is not that all, or all but one, are wrong, but on the contrary that all are correct. I was, and am still, unable to escape the implications of the fact that each of the theorists in question was, after all, concerned with one and the same human being. Instead of rejecting all such views, I found myself essentially rejecting none. This shift of emphasis is, I believe, crucial. The task is changed from one of selection to one of assembly."
In various chapters of Total Man Gooch outlined what would become the basis of his theories when he showed that phenomena can be divided into two columns, which he titled System A and System B. These could be roughly equated to Freud's Ego and Id, and in some ways Carl Jung's Male and Female principles.
It is in Total Man that Stan Gooch first gave an outline of what become known as the Hybrid-Origin theory, as well as speculations on the structure and development of the nervous system, the nature of consciousness and Psychology, all of which are expanded upon in the next two books of his trilogy, Personality and Evolution and The Neanderthal Question. In his book Right Hand, Left Hand: The Origins of Asymmetry in Brains, Bodies, Atoms and Cultures Chris McManus, a psychologist at University College London, has described Stan Gooch's ideas about the origins of left-handedness as "myths" and stated that they lack any supporting evidence, although this conclusion was based on one paragraph of Gooch's work. Colin Wilson has said Gooch's work forms "one of the most impressive and exciting intellectual structures of the second half of the twentieth century."
