I’m not sure if this is quite what you’re looking for, but one thing I do is store things I need for work and travel in consistent bags.
For example, my work laptop and my badge live in specific parts of a work-specific backpack, and I never the leave the badge anywhere except in the specific pocket of the backpack or attached to my belt.
For travel, I keep a couple things that are annoying to forget in my carry-on bag (travel-sized soap, conditioner, toothpaste, an un-opened toothbrush, a multi-country power-adapter and a spare swim suit). A battery and anti-nausea meds live in a specific backpack.
There’s trade-offs with some of these (it costs money to have an extra swim suit and backpack—if you don’t already have them), but some are basically free: the anti-nausea meds and badge need to live somewhere, so why not in the backpack I’ll always have on me in the situation where I need them?
This is what I came to ask about. Randomizing based on health and then finding that the healthier group makes more despite other factors seems like it doesn’t really prove the thing the paper is claiming.
Although the fact that wages matched between the groups beforehand is pretty interesting.
