They did test it years ago lol and confirmed that closing the lid did not have a benefit.

People usually see the initial drop of visible particles to mean closing the lid is better but it just causes the mist to aerosol more into nano particles when the lid is closed. I don't have the study itself handy at the moment, let me dig a bit more but I did find this article which was referencing similar findings. Let me try and find the paper itself though, but in the meantime here is a small except about the study from a site that was promoting the conference where it was presented at:
How does flushing water create air pressure? Are you using a steam toilet? Are you acoustic?
Did you just try to call me dumb when you don't understand physics?
Here's a little science experiment and explanation for you:
Water in a toilet bowl first rises as the flush begins before it over comes the pressure in the drain trap. Close the lid, more air is squeezed out the sides of the toilet for a moment as that happens, leave the lid up and you have a larger volume for the air to be offset in. Don't believe me, flush the toilet with the lid down, wet a finger with water slightly and put it near the opening between the lid and the bowl, you will feel it cool down from the air escaping. Do the same now with the lid open and you will notice this effect less. Obviously do this with a clean toilet and wash your hands afterwards but you will notice the pressure difference in the beginning.
No it actually does not, it increases the spread and creates a pressure build up compared to being open, you are initially adding volume into the toilet when you flush with the lid closed this pressure build up is greater and spreada the particles further. You are essentially creating a shit nozzle on the sides of your toilet. All the lid does is help the particles become bigger so there are fewer visible particles but they are bigger and travel further, while remaining airborne longer due to their velocity.
The closed lid increases air speed, not decreases it as you create a higher build up of pressure 🤦♂️
Actually it doesn't, flushing with the lid closed can leave the particles in the air for up to around 11minutes longer as they exit the side of the toilet with more velocity and pressure. It's not a sealed system.
Lid up when flushing means the particles stay in the air for less time vs closing the lid. Closed lid creates more pressure, and the particles will also travel farther.
Not how it works, sorry to tell you. In fact, putting the lid down means you are keeping those particles airborne for another 11 minutes or so due to increased pressure with the lid down.
They also, for some reason, last about 11minutes longer in the air when closed. The studies are misleading because they say there are fewer visible particles, but the bacteria count remains the same.

Why so they want to be some corporate slave for labor, fuck off
Home toilets use the bowl filling up to create a siphon through the drain trap. For that to work your toilet must first raise the water level above the top of the trap to create the pressure with its weight to start the siphon. I.e with the lid closed you are forcing more air to compress in a smaller volume generating a pressure difference outside the bowl and internally. Leave the lid open and that volume of air goes directly into the room without much resistance creating less pressure in the bowl compared to the surrounding air in the room. Hence with the lid open the distance, the spray travels is lower as it has a lower velocity.
