Why a woman has to play dumb to man [though she is not]?

Question

Is it that she is more occupied with her body than mind. Who will help her?

Answer 1

I found that I get a great response from a man when I act dumb.

Besides, it's known that men like to care for women too, we build up your macho when we do that..so why not?

Answer 2

She may think that the man would lose interest in her if he knew that she was smart, possibly smarter than him.
