I think a lot more people could become polymathic given the right personality traits and life oppertunities.
They have to cope in a society where they have to wage, they have less ability to engage into polymathy.
Polymath to me is being profiecent at 3 seperate fields atleast one sciences and one arts.
Lets say we have 1000 people.
They spend 10 years as NEET's.
All of them are supposed to work towards polymathy.
How likely are they to become polymaths?
What would the results be?
