Great thoughts! It was hard to say epistemic humility out loud though :-).
As writes, its important to emphasize what we know and what we don't. Many a times, we get into the "preacher" mode or "prosecutor mode" and forget to be in the "scientific mode", which allows us to openly acknowledge what we know and more importantly what we don't know and then have the intellectual curiosity to know the unknown parts and then use that to either refine our argument or even take a different stance altogether.
Adam Grant has called this as "scientific thinking" and wrote an entire book called Think Again, where he talks about developing such a mindset.
