There’s a University of Cork study showing that putting the lid down aerosolises more material so spreads bacteria etc. over the whole room, whereas having the lid open produces a smaller number of larger droplets that nearly all just fall straight back into the toilet. The lid is not sealing the toilet and preventing the need to clean the bathroom.
My comment was explicitly pointing out that closing the lid can have the opposite of the intuitive effect and make things worse even though you’d expect it to make them better. It seems that I misrepresented the study’s findings, though, as while closing the lid does make particles remain airborne for much longer, so my overall point is sound, closing the lid does reduce the number of particles that initially become airborne.
I can’t get the full text, but https://www.microbiologyresearch.org/content/journal/acmi/10.1099/acmi.fis2019.po0192 has the abstract. It looks like I misremembered its findings (or remembered an article that oversimplified them), though - having the lid down does something to the released particles to make more of them stay airborne for much longer, but it does reduce the number that escape, like you’d expect.
Put the seat and the lid down before flushing.

I think I did not understand your comment. Isn’t it the other way around?

Can you link that study please?

I just put the lid down but I still leave the seat up when flushing.
That’s a weird loo. :)
