Intuition is information that comes to your for your sub-conscious or unconsious mind. It is only as good as the lifetime information you have put into it. If you've put in garbage, you will get out garbage. That is why so many people's intuition is wrong. There's nothing magical about it. It's very simple. It's your brain working superfast to give you the answer you need from all your accumulated knowledge (most of which you have long forgotten).
