I think it was during the pandemic that many people saw real science unfolding almost in real time. Until then most people only had the orderly, bite sized chunks in school. Which give the illusion that science is always an orderly process.

But real science is messy, with an educated best guess proven or disproven. Lather, rinse, repeat. It does amazing things but orderly, it is not.

And these many people got very upset and decided it's not a good thing because it's not crisp, black and white and unchanging.
