Intuition, as I understand it, is unconscious calculation,, which often looks like pattern recognition. For example, when one is brainstorming ideas, all these generated ideas are intuitive because they are brought to the conscious from the unconscious. The analysis of the ideas is usually nit intuitive, but the ideas themselves are unless they are analyzed derivatives of some other given thing. Intuition also can look like "This guy seems shady, but that's just my intuition." There are some unconscious calculations going in there. Perhaps it is the facial structure or tone of voice. We aren't aware of any of these things, and this is intuition. I suppose you can only "learn" intuition by experiencing more things or gaining more knowledge. This build-up of experiences will increase your pattern recognition ability. But there is no simple way to garner an unconscious ability by that very nature. I do think it's likely that people have various abilities and skill levels with intuition which are largely genetic as it is a difficult skill to grow. At least, I don't know how to develop it strictly speaking.
