I'd like to start giving people the option of commenting on shorter Cold Takes pieces (which I don't cross-post here or provide audio for). I'm going to use this post for that: I will generally leave a comment for each piece, and people can leave their comments as replies to that.
This seems implausible to me, unless I'm misunderstanding something.
Are all such geniuses pre-1900 assumed to come from the aristocratic classes? Why?
If no, are there many counterexamples of geniuses in the lower classes being discovered in that time by existing talent spotting mechanisms?
If yes, why would this not be the case any more post-1900, or is the claim that it is still the case?
