There is a surprisingly large amount of bad science out there. And we know it. One of my favourite writeup on the subject: John P. A. Ioannidis: Why Most Published Research Findings Are False
https://pmc.ncbi.nlm.nih.gov/articles/PMC1182327/pdf/pmed.00...
John Ioannidis is a weird case. His work on the replication crisis across many domains was seminal and important. His contrarian, even conspiratorial take on COVID-19 not so much.
This is a great paper but, in my experience, most people in tech love this paper because it allows them to say "To hell with pursuing reality. Here is MY reality".
