But memory often suffers from the disturbing interference of unconscious contents.
Archetypes of the Collective Unconscious
Unfortunately, the facts show the exact opposite: consciousness succumbs all too easily to unconscious influences, and these are often truer and wiser than our conscious thinking.
Also, it frequently happens that unconscious motives overrule our conscious decisions, especially in matters of vital importance. Indeed, the fate of the individual is largely dependent on unconscious factors.
Careful investigation shows how very much our conscious decisions depend on the undisturbed functioning of memory.
But memory often suffers from the disturbing interference of unconscious contents.
Moreover, it functions as a rule automatically.
Ordinarily it uses the bridges of association, but often in such an extraordinary way that another thorough investigation of the whole process of memory-reproduction is needed in order to find out how certain memories managed to reach consciousness at all.
And sometimes these bridges cannot be found. In such cases it is impossible to dismiss the hypothesis of the spontaneous activity of the unconscious.
Another example is intuition, which is chiefly dependent on unconscious processes of a very complex nature.
Because of this peculiarity, I have defined intuition as “perception via the unconscious.” ~Carl Jung, CW 9i, Para 504
