It is the same as instinct, at least to some degree, I believe. I always trust my gut, and anytime a situation has come up where it is described as “woman’s intuition” it was really just a gut feeling. Instinct is just a hunch, or a feeling, a gut reaction… and we don’t discredit that. I’m not sure that it is necessarily something that only women have, I just think it is used to describe the reaction to circumstances that affect women more often than men.
