If you want to counteract the narrative bubbles that you're operating in, you need to work hardest to counteract the one that is the default. If you're like most Americans, you're probably immersed in left-leaning thought. The Left owns the culture. They own the major institutions that are shaping society through Hollywood, academia, sports entertainment, the music industry, social media, etc. They own the bureaucracy that has pretty much eaten up the US government. Even longtime bastions of the Right like the military, FBI, etc. have been taken over by the Left.
If you just consume random media, you're getting the left-leaning perspective. It's the right-leaning perspective that you probably have a deficiency of unless you make a great deal of effort to swim against the current.
Take, for example, Haidt's work on analyzing how well different political ideologies understood each other.
The bottom line: Moderates and Conservatives understood the Liberal perspective better than Liberals understand other perspectives.
