Anecdotal but it may have to do with both. Men have to be successful financially to get a partner so they are inclined towards entrepreneurship to get success, fame and women. Women aren't expected to do such things and they don't need to be successful in their career to get a partner. Men are expected to be funny while looking good to attract a mate so they develop their sense of humour. Women are expected to be motherly and don't need to be logical so they see little gains from going into the sciences. It is socially structured as a result of biology and nature itself suggests so.

A study showed that women have IQ's close to a 100 with little deviation towards the high and low end while men's IQ is spread across the spectrum. This is why most business people and astrophysicists are men while most people in mental asylums are men as well. It makes sense, men are throwaway by nature as 1 man can impregnate many women for the growth of the populace but every woman is needed to give birth to children so nature is experimental with men.

Yeah, you lost me here. What study are you talking about? Even if that's the case, there are still extreme flaws with measuring by one's IQ. Women don't need to be logical? In fact, it's the exact opposite, women need to be logical because would you want an illogical person raising a child?

Your rant breaks down to white+straight+male is the default, and you need a specific story-driven reason to deviate from that.

Call me crazy, but even as a white straight male, I have enough empathetic capability to be able to play as, say, a black lesbian female and not freak out about it.

Which is literally what I said in the post you quoted a few posts ago.  

Both culture and biology impact these types of things.  

Women need to be logical but don't require the reasoning abilities needed in stuff like stem fields. Everyone needs practical intelligence, that goes without saying. This is my interpretation based on what I've experienced in school, college, events, gatherings and talking to people from all walks of life.

I'm not saying IQ is everything but there is a reason it is used as a metric in so many areas.

The first software developer was Ada Lovelace -> a woman.

My boss is a structural engineer woman. I had good bosses guys and good bosses women and bad bosses women and bad bosses man.

There are guys I know that would not work for a woman. I don't give a shit. They are equal for me in terms of jobs capabilities and accountability.

 lI could not care less of a crap if women are all around in media.

Is different at minimum. Difference stimulates creativity.

Move on with your life.

Don't be afraid and complaining of losing you masculine identity all the time and crying about women taking on the media movies game whatever you play on your ass seated down.

That is not manly. That is childish.

I haven't seen anything you've shared that compared biology and culture.  

The monkey study doesn't talk about culture at all.  There's nothing substantial in the firedfortruth article comparing the two either either.  

Just because people aren't doing something, doesn't mean they don't want to.  I'm not currently doing the job I want to.  

There are certain jobs I would like to do, but probably won't.  

I have personal experience of women not being sure they wanted to go into Computer Science, because it's a male-dominated field. So yes, these things do happen.  Even if there are biological factors that would drive women into different fields, I have personal experience that shows there are also cultural factors. 

Literally no one has said this is some kind of conspiracy.

What is being said, is that women have a perception of certain fields being more for men.  And having female role models in those positions makes it more likely for women to consider those positions.  

Except the government isn't doing anything.  The people who are doing the most to get people involved in certain fields are private companies, and universities.  Companies like Google, Intel and Facebook, they're the ones that are working on hiring more.  It's not the US government that is doing anything to get women into fields.
