So have you studied implicit learning, tacit knowledge, and/or expert intuition? All of those scientific disciplines have broadened the definition of intuition to include reason. So perhaps we're just having semantic difficulties here? But I think that as the science progresses, we're seeing that more and more of what's traditionally been called "intuition" is more aptly named "expert intuition". Again "expert intuition" assumes reasoning.
You label implicit learning, tacit knowledge and expert intuition as "scientific disciplines" which tells me that you are far more impressed with these ideas than I am. However, I'd like to focus on the remarkable phenomenon of moral intuition (conscience).
Imagine a soldier willing to kill the aggressor-enemy in a just cause who is given an order to kill civilians. His conscience immediately feels the wrongness. If he obeys the order his conscience will nag him with guilt for the rest of his life when he remembers his immoral act.
Now consider that:
1) Human acts happen in an almost infinite variety and yet the soldier's conscience was able to immediately judge this specific act immoral.
2) There is no conceivable way that one could become an expert in this kind of decision.
3. The IQ of the soldier is not a factor. In human experience, we have never even suspected a correlation between intelligence and moral character but there is certainly a correlation between IQ and the ability to reason.
4. As Jon Haidt's (2000) research found, any reason the soldier might give for judging the act immoral would be after the judgment was made and would quite likely make no sense.
5. Learning and experience would be involved in "expert intuition." The Moral Sense Test, online now since 2003, tracks responses to a series of hypothetical moral dilemmas. These responses have proven to be remarkably consistent, regardless of age, gender, religion, or cultural background. Isn't it obvious that their moral intuition didn't develop from reasoning?
