Great. It sounds like may reasonably be on the same page at this point.

To reiterate and clarify, you can pretty much make the standards as high as you like as long as: (1) you have a good enough grip on how the elite class thinks,(2) you are using clear indicators of trustworthiness that many people would accept, and (3) you make a good-faith effort not to cherry pick and watch out for the No True Scotsman fallacy. The only major limitation on this I can think of is that there is some trade-off to be made between certain levels of diversity and independent judgment. Like, if you could somehow pick the 10 best people in the world by some totally broad standards that everyone would accept (I think this is deeply impossible), that probably wouldn't be as good as picking the best 100-10,000 people by such standards. And I'd substitute some less trustworthy people for more trustworthy people in some cases where it would increase diversity of perspectives.
