We do have shared values that are universally agreed. Everyone wants their kids to grow up to be capable and successful and happy. Everyone wants clean air and water. Everyone wants to be able to make a living. All three of those things are being misrepresented and argued over in the ‘culture wars’ despite the fact that we all share these values. I even might argue the whole reason we fight over them is precisely because they are shared values so it’s relatively easy to create arguments where both sides can be right about some core principles and both sides demonize the other over minutiae, and it stays that way.
The debate over trans people has surfaced lots of incidents in which people will say, to the world and to the faces of their kids, that they would prefer them to be dead rather than transition. Sometimes they take steps to ensure this themselves. https://www.independent.co.uk/news/world/americas/eden-knigh...

.. for themselves. There's always someone who realises that they can make a billion dollars by pouring carcinogens in the river, so why shouldn't they as long as they stick to bottled water?
Everything is simple and happy until we get to having to make a tradeoff.
If you can dig through the incredible dense ideological jungle of liberalism and conservatism, you'll find that they really boil down to societal responsibility vs self responsibility, and that in any given scenario both of those are viable takes with their own set of pros and cons.
That's quite a hard task nowadays; given how polarised society is (at least in the US), the list of shared values may be quite small.
Most Republicans and Democrats are moderates, and the polarization is coming from loud vocal minorities at the fringes. Republicans and Democrats erroneously assume that the other party's median is far more extreme than they really are.
Most Americans share far more values with each other than they do with the Woke/Maga extremists.
If you want to know what the consensus of a specific echo chamber would be (aka, what the stereotypical pov is), having models trained to represent that echo chamber would be incredibly valuable imo.
If you want a sum of all echo chambers, you will obviously need the echo chambers to sum first.
