I have been reading some essays concerning the epistemic reliability of intuition. I recall once while reading Jung, I came upon a passage of his in which he explained that intuition is actually empirical knowledge that we possess, but leaps forth to the mind in such lightening-like action, that it seems almost "magical". In reading through a PhD dissertation of an I. Simic of the University of Flordia, I found this asserted most strongly: That intuition is epistemically stronger than evidence because it is knowledge.
When I was studying philosophical jurisprudence I was profoundly impressed by Joseph Hutcheson's, "The Judgement Intuitive: The Function of the 'Hunch' in Judicial Decision", which reversed common ideas about cognitive process. Highly complex data and stimuli can be rapidly classified, as in the case of the skilled airplane pilot or surgeon, who often recacts and acts within a context of split-second decisions.
There is a British author, Anthony Peake, who has developed a theory of binary mind, in which the mind is comprised of a dyad of eidolon and daemon. These correlate, respectively, to the conscious and unconscious mind, with an interesting twist: through the use of cognitive science and quantum physics, the daemon is linked to the eternal, in terms of eternal recurrence and Many Worlds theory. If his theory is true, it would add a dimension to intuiton, becuase this knowledge would be recalled from previous runs of existence.
Gnosticteachings.org has a wonderful forum (http://www.gnosticteachings.org/) in which intuition is discussed in terms of "The Revolution of the Dialectic"........
