This is what I was thinking as well as I followed this thread. What we call "intuition" is often a conclusion from our subconscious mind based on cues and observations of which we may not be explicitly aware.

In other words, our mind is constantly watching and learning, and then matching that data to patterns we've observed in the past; not all of this information reaches the front of our consciousness.

Of course, if it's subconscious, it is easy to get misled, or match patterns inaccurately since there is no rigorous examination involved about the underlying assumptions.
