I don't think neural networks have the same ability of self deception as humans do. A huge reason human world models vary so much is due to them being tied to tribal membership. A huge fraction of all people will not come to a rational worldview derived from accurate data but will start with their tribe's worldview and filter data to match. I personally have never modified my worldview for social reasons and it is surprisingly isolating.

This. I believe most people don't act as if objective reality matters, hence their worldview can be arbitrarily aligned to the demands of their social context.

Suppose these two premises are true: 1. Objective reality exists. 2. There's a model and corpus of data that converges to approximate reality better than any other model.

Now, suppose we train different models with data sources restricted to different tribes/ ideologies/worldviews. Can we discover how their internal representations differ from each other, and from objective reality? What would we do with that knowledge?

There is universal objective truth, and different opinions or world views are just "tribal membership". If onlymother tribes understood that!
