Some like to think of intuition as a magical power. In reality what is at the heart of intuition is miniscule data. A person known to be particularly "intuitive" is someone who has learned to get in touch with such data. Perhaps they are good at detecting lies. Whether they realize it or not, they have picked up on certain cues provided by people throughout their lives who they know have lied. Maybe it is a tone of voice, an eye movement, facial tic... The possibilities are truly endless.
From my study of human temperament, it's clear that women are generally more intuitive than men. What this means is that about two thirds of women are more intuitive than they are concrete. But it's also true that one third of them are less intuitive and more concrete, and roughly one third of men are more intuitive. So it's certainly not across the board.
I've known and paid close attention to highly intuitive people--men and women--for years. They certainly have some advantages--but I'm convinced it can also cause them problems. The problem with many highly intuitive people? They are right just enough of the time so that they get to thinking they're ALWAYS right. And they're not. No one is. Example...
HE: Well it was nice to get together with Bill and Sue tonight.
SHE: Did you see the dirty look Sue gave me?
HE: Dirty look? Uh, no...
SHE: Oh yes, she very definitely gave me a dirty look.
HE: Are you sure? Look Sue was happy to see you; remember how she gave you a big hug?
SHE: And I know why she gave me that dirty look too...
HE: Do tell.
SHE: She's mad at me because I didn't go to the movies with her that time.
HE: The movies? That was like eight months ago!
SHE: I know--can you believe how she just can't let it go?
Now sometimes she's right, but sometimes she's not. And the problem with many highly intuitive people is they remember all the times they were right in their intuition--but often forget or dismiss all the times they were wrong.
