This seems like something that should be true, but I think I remember seeing a Mythbusters episode where they decided it didn’t make a difference. That show was more about entertainment than science, so I wondered if there was a more rigorous study done? I’ve definitely seen splashes of water(?) come out from flushes so that alone seems to argue for closing lids.
It makes sense in some regards because with the lid closed you don’t have air flow so therefore you would have microdroplets suspended in the air in the bowl. I’d rather a longer loiter time in the bowl than dispersion into the greater area.
I just re-read your link it to see if it mentions where the sensors are; I’d assumed the sensors were outside the bowl since that’s what people are interested in but it doesn’t say.
The paper is available, but as a layman the “read full text” path just takes me in a circle.
