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.
Once you see the term “fecal plume”, you’ll see the need to close the lid.
That assumes that it is worth avoiding a “fecal plume”. I would think that useful research would tell us whether such a thing is actually bad for us, beyond sounding gross.
