I am originally a Physicist (worked 5 years as a researcher in academia for my PhD and postdoc in end 90s, beg 00s). I couldn't agree more with what you are writing. imho, Intuition is actually triggered by the unconscious brain synthetising various experiences and providing a deduction. This deduction, the unexplained reason why that way to go seems interesting, is what is called intuition. It is also a very close cousin to creativity.

I do believe thus, that intuition and creativity are fundamental ingredients to the generation of new ideas and research directions. So, to have a valuable intuition, one needs to experience, leading back to your article and your field. Egyptologist shoudl definitely impregnate themselves with Egypt and stay there for extended periods of time!
