With respect, I asked for data and you came back with “it seems obvious to me…” without citing any real data. I know enough to know people who make feelings-based arguments can’t be persuaded by data-driven discussions.
A reference is not an appeal to authority, it’s an opportunity for you to verify the stance and poke holes in it if you have the capability to do so. You have the opportunity to use whatever authority you want and cherry pick data. I’m just asking for an effort that has some rigor beyond “I can’t prove it, I just know it’s true because my gut tells me so”
