It’s a reference to an attitude that is prevalent in conspiracy fantasy circles. It’s a deflection of ownership of ideas to lend them more credibility, it’s not actually about researching anything. There is no discussion about research conclusions or facts. there is discussion, but it’s the exact opposite of research, it looks like, what questions give the right answers and how to connect the conclusions to the data. What they mean by saying ‘research’ isn’t what it actually means. Conspiracy fantasy wants you to stumble upon coincidences to lure you into their worldview.
