As humans, we align to our experiences and values, all of which are very diverse and nuanced. Reminds me of a friend who loves any medical conspiracy theory, whose dad was a bit of an ass to him, and of course, a scientist!
Without our cognitive biases, are we truly human? Our values; our desired outcomes inherently are part of what shapes us. and of course the sources we choose to trust reinforce this.
It's this that makes me think AGI can never be achieved, or human-like ability for AI to think, because we are all biased, like it or not. Collectively and through challenging each other, this is what makes society thrive.
I feel there is no true path towards a single source of truth, but collaboratively we can at least work towards getting there as closely as possible
