I would say that nobody agrees, not that nobody knows. And it’s reductionist to think that the brain works one way. Different cultures produce different brains, possible because of the utter plasticity of the learning nodes. Chess has a few rules, maybe the brain has just a few as well. How else can the same brain of 50k years ago still function today? I think we do understand the learning part of the brain, but we don’t like the image it casts, so we reject it
That gets down to what it means to “know” something. Nobody agrees because there isn’t enough information available. Some people might have the right idea by luck, but do you really know something if you don’t have a solid basis for your belief but it happens to be correct?
Potentially true, but I don’t think so. I believe it is understood and unless you’re familiar with every neuro/behavioral literature, you can’t know. Science paradigms are driven by many factors and being powerfully correct does not necessarily rank high when the paradigms implications are unpopular
