With his essay Flying Saucers: A Modern Myth of Things Seen in the Skies (1958), Carl Gustav Jung can be seen as one of the founding fathers of the Psychosocial hypothesis.
In ufology, the psychosocial hypothesis, abbreviated PSH, argues that at least some UFO reports are best explained by psychological or social means.
It is often contrasted with the extraterrestrial hypothesis (ETH).
Some also say that because of his use of the concept of synchronicity in this book, he is also one of the founding fathers of paranormal explanations of the UFO phenomena. ETH advocates sometimes say that while Jung approached UFOs psychologically because he was a psychologist, he was also on record as stating that some might be true physical objects under intelligent control, citing in particular radar corroboration. They say Jung truly seriously considered the Extraterrestrial Hypothesis. The Associated Press quoted him in 1958 saying, “a purely psychological explanation is ruled out.” The flying saucers were real and “show signs of intelligent guidance and quasi-human pilots. I can only say for certain that these things are not a mere rumor, something has been seen. …If the extraterrestrial origin of these phenomena should be confirmed, this would prove the existence of an intelligent interplanetary relationship. … That the construction of these machines proves a scientific technique immensely superior to ours cannot be disputed.” Disciples of Jung have offered thoughtful rebuttals.
“I was quoted as a saucer believer. I issued a statement to the United Press and gave a true version of my opinion, but this time the wire went dead: nobody, so far as I know, took any notice of it, except one German newspaper… one must draw the conclusion that news affirming the existence of Ufos is welcome, but that skepticism seems to be undesirable. To believe that Ufos are real suits the general opinion, whereas disbelief is to be discouraged… This remarkable fact in itself surely merits the psychologist’s interest.”
