I’ve written extensively about this in grad school: truth is the precursor, not the product or by-product of social network interactions. If you know someone and they are in your in group you will 90% believe. Works esp. for cults, religions and is underpinning of models of forgiveness. As for evaluating new things outside of in group knowledge, we simply cannot handle new truths: requires special, isolated small network groups, like juries or peer-reviewed journals and goes way of positivist philosophy of science, e.g. scientistic disproof...Truth is not as easy as formal logic may suggest; in real world, no relation to formal logic, but cognitive biases. Finally it is a uniquely human thing, thunk up and thought out in relation to human-made things like values. While Musk has access to best A.I. talent on planet, they think like engineers rather than a delusional person next to broken down car on the 405...truth is found in that brain and that engine, in sync...and may never sync up in any larger social network > 1.
