They established this in one of the most disturbing MythBusters episodes years ago.

edit: actually, I’ve realized in that episode that the toilet didn’t have a lid, so while the experiment wasn’t the same, you can probably draw the same conclusion when control toothbrushes outside the bathroom were also affected

Mythbusters busted this myth long before studies. Turns out that air pressure is enough to push the particles flying from the bowl despite the lid, because the toilet lid isn't a good air tight seal, and the air is pushed out due to water volume increase.

So basically closing the lid doesn't help.

You need to buy disinfectant, says company that sells disinfectant

half of yall be eating ass but also worried about a little shit mist. you definitely don't want to know about farts.

I mean, fair; the lid isn't a total seal so I expect it to be able to kinda come out around the edges of the lid; but wouldn't it still keep all the stuff at least in a smaller area? It's not blasting straight up in the air with the lid blocking it, is it? The floors and baseboards get cleaned pretty frequently; the ceiling not so much.

Still gonna do it.

Every single thing in the world is covered in a thin film of bacteria

Not only that but the bacteria are constantly pooping on you

Also there are mites having sex on your face and burrowing into your hair follicles to hang out down there with their back ends sticking up into the air

They look like this

To be honest, the "study" reads like a Lysol Power Toilet Bowl Cleaner advertisement.

What previous studies? Wasn't there a mythbuster episode where they tested that like 15 years ago?

For all the people wondering if it's better to close the lid or leave it open. The point of the study and numerous others before is that it doesn't matter lmfao.

If you feel better with the lid closed and want to look down on others who keep it up, no amount of studies are going to change your mind. That's why you're in here asking for more while choosing to ignore this one, and the last ones, and mythbusters...

And because there's some weird overlap between ya'll... Yes, squirt is pee. There's no magical 4th dimension bladder ovaries that allows you to piss all over someone and call it female jizz.

Surely it's still somewhat better than leaving the lid up though? Obviously not perfect but still.

So the solution is to never flush.

Well shit

Hmm time to replace all toilets with friggin' autoclaves.

So, uh... design better lids?
