Just don't like seeing misleading info spread around as honestly the science behind it is pretty interesting.

I don't want to step on your toes, so hopefully this doesn't come across that way:

You mentioned Myth Busters and an article from 2019 on microbiologyresearch.com in another comment .

Let's just say without further elaboration, that Myth Busters are not a solid scientific source.
I couldn't really find a paper from the article you linked in another comment. Just this: https://www.microbiologyresearch.org/content/journal/acmi/10.1099/acmi.fis2019.po0192

I don't know whether it's an issue with the website, but currently I can't see much else besides some text which sounds like an abstract. This makes it currently difficult to see this as a good source or estimate the quality of the work. Judging on this abstract alone, although it mentions that the time particles are detectable is about 10 minutes longer with the lid down, it also reports a 30 to 50 % decreased amount of particles. It also states a lack of research regarding smaller particles.

As far as I can see we could safely say, that this issue, whether it's better to keep the lid up or down, is still debated and a final verdict is still out:

https://doi.org/10.1016/j.jhin.2011.08.010

https://doi.org/10.1063/5.0040310

https://doi.org/10.1063/5.0013318

https://doi.org/10.1038/s41598-022-24686-5

However, to me it seems that there are indications that a combination of proper ventilation and closing the lid might be better than an open lid.
