'its old so we can assume everyone shares the same information and perspective' is a bad way to do decision making and argumentation full stop. Topic and perspective independent.

One of the things I used to see pushed back on, but it seems to have gone by the way side recently, is not citing the original source but rather citing the someone saying something about the source. Its increasingly pervasive in all types of research adn contributes to a giant and slow moving slide of meaning creep.

The OP mentions that reviewing the history would inform the discussion. You dismissed being informed and simply provided a truism - specifically accepted a truism common from oen side. If the issue is confidence in integrity, but there never was an integrity issue, then fixing an integrity issue is neither possible nor a solution to the confidence problem.

Again, I see this everywhere - from polite conversation to academic discourse adn it troubles me about the larger state of knowledge and knowing in the world.
