I think what you’re missing is that academic research focuses on novelty, not basic facts. Ultimately not trusting novelty can save time. Basic facts can be found in reference material.
So it’s more like suppose you want to paint your house green, and you read that somebody says you can mix red and blue paint to make a really cool green paint. Instead of immediately going out and buying enough red and blue paint to cover your whole house, first buy a small amount of red and blue paint, mix them together, and see if you get that neat green paint.
It’s common sense, but the window dressings of academia can lead you to burn time and money on things that are totally silly because somebody important-sounding said they did it once.
Where people get burned is that there’s an enormous power imbalance—-junior scientists can end up stuck trying and failing to make green paint out of red and blue paint because nobody senior is going to take them seriously if they can’t make green paint. This presents a serious ethical challenge if making green paint is impossible.
