14% is a lower bound. I suspect if you include studies that can't be replicated it's well over 50%. And yes with that much garbage the public should dismiss all new published scientific findings. Modern scientific publishing has been gamed it's nearly useless for learning anything directly because you can't trust it. Some fields more than others of course, but it's all bad. Yes this includes tier 1 journals.
This has always been true? The vast majority of scurvy research was unreplicatable bullshit, and for hundreds of years if you “Trusted the Science(TM)” on scurvy, you were liable to die horribly on long ocean voyages. Mind you, if you didn’t Trust the Science you’d die just the same.
Then, someone worked out a theory and replicable experiment (humans and guinea pigs are the only mammals that die horribly when not fed vitamin C) and with a replicable experiment in hand, you could use little s science and now no one gets scurvy, trust not required.
