Interesting article, though I doubt a statistical approach to the issue is particularly valuable. Sample sizes are just too small, the cultural environment changes too much, etc. Using Schiele's death, for example, is rather pointless - the Spanish flu took lives very quickly, so it wouldn't have had much of an impact on the evolution of his practice (other than to just kill it along with him). On the other hand there is already a significant body of research work with respect to artists in their old age; while Dormandy's Old Masters
was this book was moderately well received in the popular literature 15 years ago or so.
As for other life events among us peons, well it seems just about every other artist these days is writing about how this or that effected their art. It does get a little tiresome!
BTW, your link to the "Artnome community" at the bottom of the article is somewhat broken, the Slack page says "This invite link is no longer active./ Please check with the person who shared it with you to see if there's a new link available."
Re. the 538 article; well some people like to create conceptual boxes for everything, and then try and force things into fitting them. One of the real pleasures of art is in breaking those boxes and setting things free. So enjoy your hobby!
C&C of all sorts always welcome! (I don't mind rude or harsh criticism.)
I suppose I have to do this too
