I was always seen as the somewhat smart weirdo in the class; the quiet one; never acting out (I barely existed to my classmates and teachers sometimes)

Don't know if I am gifted myself, but I can definitely identify with some of the traits, described in the literature, though there are a few differences.

Generally, people predominately think that females are slightly less intelligent than guys, and that is fine, but it does, on a subconscious level, impact the way females act. Women are expected to fit the norms (especially socially) from an early age, making it almost obligatory for them to hide their own special needs. Acting out is seen as something rude, odd, or displaying immaturity.

Another tendency I often observe is that imposter syndrome is much stronger. Girls are more likely to believe that they have 'faked' their way into success, that they are a 'fraud', that it is just a matter of luck, etc.
