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.

Yes. Link cites researchers and institution. https://microbiologysociety.org/news/society-news/does-putting-the-lid-down-when-flushing-the-toilet-really-make-a-difference.html

Ninja edit: Does not eliminate but greatly reduces. Appears "Worth it."

The research found that putting the toilet lid down reduced the number of both visible and smaller droplets during and after flushing by 30-60%. However, use of the lid also increased the diameter and concentration of the bacteria in these droplets.

It was also found that airborne microdroplets were detected for 16 minutes after flushing the toilet with the lid down, 11 minutes longer than when the toilet was flushed with the lid up. The researchers suggest that this could be due to particles being re-aerosolised from surfaces rather than being created by the turbulence of the toilet flushing. Alternatively, the researchers suggest that airborne particles could stick together, or agglomerate, which would cause them to remain airborne for longer.

Those are fascinating findings; I wouldn't expect that in some ways lid-down is worse...
