Exactomundo! Choosing the dialogue, choosing the spin, it's one the major spheres of control.
My 'breakthrough' moment was during Covid. Just looking at all the news (from sites I deemed 'my side') without any real information, but loaded with emotional phrasing made me realize that I am being used. I love that we have multiple options for news, don't get me wrong, but I felt betrayed.
Since then, I mostly read comments or watch the video of the event the media is spinning. Comments are pretty awesome, cuz real people help digest (or misinterpret) the harsh tone of the outside world.
I'd argue it's being diluted by noise. There have always been conflicting narratives. History is so hard to untangle (for me at least), because most of us come out a bit brainwashed from the system.
I think we are seeing the ends of the safeties this form of democracy has to provide. We are all in it together, everyone hallucinating to some extent. The big difference today is that you don't talk about tv around the watercooler. You send cat pics and talk about Will Smith AI spaghetti videos, digitally or in meat space.
The problem usually isn't lack of shared context, I believe, especially when we have so much in our pockets. It's signal dilution with some plain old ill-intent under the hood (i.e. 'advanced' marketing).
