Online sensemaking often seems to require choosing between two kinds of information sources: smarter, more knowledgeable people with more incentives to lie, and dumber, more ignorant people with less incentive to lie.
The other 2 quadrants are usually either empty or easy to dismiss (dumb-ignorant with more incentives to lie = low-level easily spotted grift, smart-knowledgeable with less incentives to lie = likely to just not care enough to conscientiously supply information)
I think you dismiss the knowledgeable with less incentives to lie too easily. My feed has been full of experts with little incentive to lie over the past year.
“Integrity” is just another incentive. It means you think your intent is sincere to the extent you can examine it. Says nothing about the moral-epistemic foundations of your institution.
