Quick question on female (well, human psychology) in general. I've heard this reluctance to say no being thrown around a couple times and have had periods in my life where I personally felt intimidated by saying no.

It's very prevalent in Asian culture (I can't say no because it's not polite) in feminist culture (I can't say no because I feel threatened by disagreeing, you can't either because I feel threatened by being disagreed with) in beta mentality (I can't say no to this chick cuz she won't like me if I say no) and by abuse victims (I can't say no because I've developed a trauma center when every time I said no I'd be abused for denying my abuser's wants).

What are the differing evolutionary/historical basis behind human beings being so emotionally averse to being told 'no', or telling others 'no'? Does anyone have any articles or insights that can illustrate more trains of reasoning behind the 'bad feeling' that tells you not to say no?

I'm well aware that some people use it explicitly for manipulation purposes (ie. feminists) but I'm trying to understand the base cause for the phenomenon (which honestly has become increasingly cancerous in recent years thanks to feminists taking advantage of it) in the first place. Evo-psych anyone?
