No, I don't agree. I believe a planet needs to be in aspect to the Sun or Moon or perhaps Mercury for psychological traits of that nature. A planet in a house relates to life emphasis more than psychology. "Topics" as the ancient astrologers would say.
You're unusual, in this zeitgeist, thinking takes us back to James's question as to whether one can or should delineate ?blind faith' as a Neptunium aspect to a planet, or one of these 3, or a house position, or a sign position or does one need or rely on confirmation or clues from all of these components plus others. What is generating your own belief in Edgar?s imagined abilities for example. Ordinarily for someone with these persuasions I?d have my eye out for Sun, Moon, Asc or all 3 in Sagittarius, one or both of the luminaries in the 9th, Neptune in the 9th etc. How do you explain it?
Casting an eye over Deb H?s book on houses it seems the 'old fellows? House 9 topics tended to include religion, travel, foreigners and philosophy. If you can find something important in an astrological chart that is not psychological I think you might be up there paradigm shift wise with the likes of Darwin and Copernicus.

Edgar Cayce on Neptune
I didn?t recall Edgar coming up in any books but I checked and found this in Greene?s Neptune ?Cayce who had the Sun Mercury, Venus and Saturn in Pisces and Neptune conjunct the Moon in the 9th house (!!,) provides us with a good astrological example of a Neptunium individual pursuing Neptunian work??.
Cayce did not ?regurgitate? Blavatsky or anyone else. His sources were spiritual, and his only concern was either helping to cure his clients of physical illnesses or advising them on ways to live a life more attuned to spiritual principles.

Not odd at all. All you need to do is study the charts of those who have devoted their lives either to the study or practice of psychology.
Which has been done many a time, but here?s a quick fairly non contentious list of 10 of the top twenty re influence to peruse.
Asch, Dewey, Eysenck, Freud, James, Jung, Pavlov, Piaget, Skinner, Watson.
It?s no accident that Neptune?s trident is the Psi symbol.
Seems it?s a symbol for a lot of things

Pharmacology might be a tighter fit time line wise and its link to drugs and ?altered? states of mind.
The Psychological Neptune resonates with Transpersonal Psychology, therefore Cayce?s interest in Faith Healing / Trance. Scofield in his Circuitry book links Neptune to Robert Anton Wilson's 5th Neurosomatic Circuit idea.
Neptunian behaviours such as dissolution, masochism, narcissism, salvation, renunciation, atrophy, fusion, addiction, deception, illusion, ecstasy, etc ,are of interest to Psychologists, particularly of the Depth variety. They are somewhat removed from the main thrust of Psychology which is concerned with language, learning, thinking, perception, conformity, motivation, gender, intelligence and so forth.
Cayce also attributed the influence of Neptune to inspiration in music and the arts, and frequently advises those with a Neptunian influence to live near large bodies of water.
Which is more normal, at least the link to Music, Neptune is somewhat pre or post verbal so a writer with a strong Neptune could end up psycho babbling like Rudhyar or Tyl (before and after language).
