If intuition is 100% accurate as a couple of people here have stated, then, if something believed to be intuition is incorrect, and it was not, then it is not, by this definition, intuition. But we can only know this after the fact, when the knowledge is proved true or false. Until proven a person may continue to falsely think it is intuition.
So we need to assume that, using standard definitions of intuition, "knowledge or belief obtained neither by reason nor by perception" and "the power or faculty of attaining to direct knowledge or cognition without evident rational thought and inference" is always 100% accurate.
If such knowledge is proved incorrect, it is what? Ego? And it must be something other than knowledge obtained neither by reason nor by perception. By process of elimination, the ego must operate by reason or perception. Or is there some other thing that looks like intuition but is not really? If so, what is it called? There must be a name for this process other than ego (since ego is an aspect of self an not a cognitive process), but what is it commonly called?
It all technically comes from ego. But if we choose (for arguments sake) to not call it ego, I'd call it thoughts and personal desires (self-delusion). Desires often lead to self-delusion and get in the way of intuition. Look at the people the audition for singing shows-- and tell the camera they will be the next Crowned King! Meanwhile they can't carry a tune. Delusional? Or "Sarah" might tell her best friend, "Amy", who is having a hard time conceiving "I think you're definitely going to be able to get pregnant. I promise you! I feel it!" Yet Amy it is confirmed that Amy can't have children. Was that Sarah's ego? Was she delusional? Well, her personal desire, was so strong for her friend to be happy, that she couldn't see or feel it any other way. She was too close to the situation.
Intuition is to me, is quite simply, "lucid insight." Knowing information I have no intellectual reason to know. If I didn't see, nor read about it, nor did I hear it and it has nothing to with information I received on a mental level... then how do I know this information that has proven to be accurate? Intuition or even empathic accuracy.
