How do you think you can improve your instincts?

For the purpose of this discussion, let’s assume we are talking about CORRECT instincts. For example you get a hunch or a feeling something will happen a certain way before it does and you are right. We all have gut feelings, but frequently they are wrong. I get the impression certain people have a more accurate instinctive reflex than others. Great athletes seem like they must have better instincts than the average competitor.

How does this work, and how could one improve their accuracy?
