Lots of people know from experience that they're staring in their wardrobe every day for tens of minutes to decide what to wear and hate it.
That doesn't change for them if some experts can't replicate the original findings of some "decision fatigue" paper. The burden of choosing every day is enough, even without fatigue.
But it was fashionable to cite these studies for a while and to consciously adopt strategies based on them. That's a bit different—more like reorganizing your diet based on studies that perhaps eventually get overturned.
I don't think that would be relevant. They still have to make 2000 other decisions and micro-decisions throughout the day anyway...
Simple solution: Wear what is at the top of the clothes stack in your wardrobe and add clothes that come from laundry to the bottom of the stacks in your wardrobe (for computer scientists: Make the clothing stacks in your wardrobe a FIFO queue).
I own 3 pairs of dark blue jeans (of the same style), half a dozen tshirts (dark blue, dark grey), 4 shirts (all vertically striped).
I just wear whatever is clean, I don't think I've spent more than an hour on clothing choices in the last year (and most of that hour would have been picking a suit out).
I do make sure everything is clean and ironed though, I like to look neat if not smart.
