This is very perfectionist. Let me install my doors the way it's comfortable or pleasing. Where I see a knob I'll reach. And where I see a "pull" sign I pull, or get contex clues.

There is research for everything, let's say it's more comfortable to push and the knob is on the right side for me. I could spend way more time and effort than thia desrves to apeal to that study, "I have great UX", I'd tell myself. But then I'd show this product on some eastern market where they read in "reverse" and it'll not be comfortable nor "100% natural" for them. Meaning, I'd fail, my UX'd be horrible for half the planet.

This might be worth for universal things, that are already researched and you don't need to spend years and a kidney to figure out. Like maybe how are "next", "cancel" and "back" buttons are next to each other. But I mean.. just copy the most recent you used.
