I don't know where you did STEM related education, but in my environment a women in a group project would get extra points relative to the rest. So I saw the exact opposite of what you describe.
And at work, women seems to rise to management levels easier than men. But hey, this is EU, not US.
Edit: you're pointing me to something that happened in 1890? WTF???
You claim that STEM discriminates women today because of something that happened in 1890.
I would like to see some evidence of that related to today, not something from 1890. And not your empty statement of "what was once a pattern still persists to a lesser degree".
Doing well in classes doesn't award recognition and opportunity for men either, though. STEM only values experience.
This is the problem: It is believed that, at least historically, STEM only pushed itself on boys. They were given lego, electronic kits, etc. while girls were given dolls, kitchen sets, etc. Once one was ready to enter the working world, men had that experience to lean on. Women not so much.
I'm not sure how applicable that is anymore, though. It's quite okay, even encouraged, for girls to play with 'boys' toys these days.
> Doing well in classes doesn't award recognition and opportunity for men either, though.
Read bio's of everybody who got "Senior Wrangler" from (say) 1850 onwards, it's a great read and a number of them founded majar US seats of learning.
Now read the bio of the women who out thought all of them.
> STEM only values experience.
All of them started out as new born babies and progressed through school having no world experience until they got some on the back of offered opportunities or private wealth.
STEM today is built upon people with no initial experience who gain it along the way.
