I'd propose as an amendment that you're on to something that its cultural, but probably much less controversial in that its merely a simple sorting system.
Does it never expire? Looseleaf tea, sugar, honey, spices, salt ... that goes in cabinet.
Does it expire/rot eventually no matter if its hours or months? Simple, all that stuff goes in fridge.
No need to ponder or remember or search two places. If its eternal its stored over there, if its not eternal, it is not.
This has obvious cultural side effect with my people have large fridge and only really use maybe two kitchen cabinets unlike recent trends in American kitchen remodeling where the average kitchen has a relatively modest (stainless steel, of course) fridge with about thirty kitchen cabinets presumably full of butter and eggs and milk or something.
There are even more cultural issues... I've met people who claim to hate the taste of walnut oil because they've been conditioned to believe the only walnut oil that exists is rancid bitter and gross so people like that who none the less for some weird reason like bitter rancid oil will naturally store their oil on the shelf to maximized its awfulness, although I store mine in the fridge and its delicious even though I have to warm it each time I cook with it (ditto butter). Perhaps there are people acclimated to rotten eggs such that they would actively dislike fresh eggs. Kinda like how beer gets skunky after a couple days exposure to sunlight in a closed bottle, there are probably people who actively like skunky beer.
