> Other nations who didn't participate in WWII were largely further behind the industrialization curve
Sweden, Switzerland and Denmark (only fought for 9 hours, so it effectively didn't fight) are further behind in the industrialization curve? France, too, could be counted in this category, as their wartime contribution was largely paused from 1941 to 1945 besides partisan activity and French forces outside of mainland Europe.
The gender equality paradox is widely understood. What is motivating the instinctive dismissal of such a widely studied and known phenomenon?
For the second time, that's not what the data in your link shows. It shows a single data graph of the modern day state. It is an interesting conundrum - but I don't understand how it supports what you are saying about the historical state.
Other nations who didn't participate in WWII were largely further behind the industrialization curve. Not sure what that means for interpreting STEM data other than there wasn't as much STEM in those nations then.
