What should be clear is that neither the American nor Russian media will always be right, and neither the American nor the Russian media will always be wrong, and sometimes one will be right while the other is wrong, while other times both will be wrong or both will be right.

I mean all of that is just common sense. The relative rate at which any of those scenarios unfolds is up in the air, but it's pretty clear all of those scenarios happen at least some of the time. When you see somebody claiming otherwise (e.g. "Russian media disagrees with American media, so the Russian media must be wrong." or "American media disagrees with the Russian media, so the American media must be wrong") you can be sure their opinion is invalid. They could legitimize their opinion by acknowledging a degree of uncertainty, by adding the word "probably" to either of those statements.

Here is the key: recognizing the possibility that you could be wrong. Acknowledgement of uncertainty may run counter to ego, but it's important. Or maybe I'm wrong about that.
