archaic in jung's interpretation meant "existing at deeper levels of psyche" or in other words "original" which doesn't translate to it being "less developed" but shows that he viewed his intuition as constitutional. i looked it up on ref.
lexicon of jungian terms and what struck me as odd is that his own interpretation of this word had blatant parallels with his own description of introverted intuition:
"Archaism attaches primarily to the fantasies of the unconscious, i.e., to the products of unconscious fantasy activity which reach consciousness. An image has an archaic quality when it possesses unmistakable mythological parallels. Archaic, too, are the associations-by-analogy of unconscious fantasy, and so is their symbolism."
calling his intuition as "archaic" jung means an intuition that functions by "associations-by-analogy of unconscious fantasy" and "possesses unmistakable mythological parallels". isn't this how Ni is conceptualized in socionics? this is all too far-fetched and contradictory as an account of Ne.
