Maybe the heap of already-discovered knowledge is so unwieldy that diving into it and retrieving a particular piece of already-discovered knowledge becomes its own form of discovery. I once won a research prize for a paper which was basically "HEY GUYS HAVE YOU HEARD DONALD KLEIN'S THEORY OF PANIC DISORDER?" Everyone who read my paper agreed that the theory was beautiful and important and they'd learned a lot from it, but my apparently prize-worthy contribution was just to dig it up and show how it applied to a particular patient whose condition was otherwise mysterious. Probably a lot of work linking conspiracy theories and the discovery drive has already been done somewhere; Hon either independently rederived it, or read it and realized it applied to QAnon. Either way, he got it in front of a lot of people who were happy to learn about it and it's fair to celebrate his contribution.

The obvious next question - is Coplan Sr’s work on panic disorder any good? Answer: yes! - he co-published with Donald Klein, whose ventilatory hypothesis of panic revolutionized my understanding of the condition. Great Families theory undefeated.
