I agree

I understand, one can manufacture a playbook to analyze an individual, just like the one you provided for my two questions.

Still, the problem remains, as it is with most human interactions, there’s no objective answer, it all varies based on human nature and the environment involved.

What is their track record? If it’s consistently good, then that’s kind of a really strong voucher, no?

Indeed It is an indication, but it does not guarantee an absolute answer like: Helium is heavier than Hydrogen; a fact that can’t be disputed.

Can you verify that everything, or at least most of what, they said is correct?

True, you can do that, but if one is asking for another’s opinion, it is hard to evaluate it yourself, there’s bias all around us, more so when we are not aware of it.

I understand your approach, and maybe I’m being a bit pedantic, but I can’t see how this isn’t a really complex problem, with no exact solution.

How does one know if another is mature enough to give truthful and honest feedback? Furthermore, how does one discern if said feedback is actually truthful and honest?

Feels like a simple problem, but the underlying social logistics is quite intricate.
