I have read that Canadian Geographic magazine ( like National Geographic magazine, but colder ) decided to fire their photo-editor.
It's a photo-centric magazine.
So, their quality dropped.
& that had consequences..
Since I only read 1 source for the story, I've no idea if it tests-out, but that is exactly the problem with hard-to-grow expertise: you don't know how much worth it is, until you lose it, & then you can't quickly/easily get it back.
( this story is actually a good example of why people should be tested for roles the're not even close to working-in:
it'd help one calibrate the difficulty-in-replacing particular people, AND it'd identify if you even can replace them, & if not, get training backups or get bringing-in people, until you've got a backup, eh? )
Anyways, until a person has worked-through Betty Edwards' "Drawing on the Right Side of the Brain, the 4th Definitive edition", & experienced the hemisphere-dominance-shift, themselves, it simply isn't understandable how meaningful that shift is.
( also, it validates exactly what Hofstadter wrote "Godel Escher Bach: An Eternal Golden Braid" about: that each kind-of-knowing is incapable of knowing ANY meaning which isn't within-its-kind-of-knowing. )
