Why are Pollsters Wrong?

Why pollsters this year were as wrong as last year is going to be source of endless punditry. This will be doubly true over the next few weeks as news networks struggle to avoid uncomfortable riot coverage.

Some people push a DNC-media collusion narrative with respect to systemic polling bias. I just don't buy that. While I'm sure some "news" agencies purposefully push misleading polls in order to grab attention or sell a narrative, I really doubt the aggregate of polling institutions do this.

Rather, it seems likely pollster's just haven't kept up with the demographic shifts that track the moral changes now occurring in political-group identity.  An example in simpler terms may be apt. The left's intersectionalism now means they're the party of "racists" (classical racists at least). See California prop #16.  This has shifted a lot of classical liberals over into the Trump-if-I-must camp. Similarly law and order has shifted a lot of inner city minorities into non-traditional political camps. And, the very wealthy have shifted from Republican to Democrats. Never Trump neo-con's are the obvious example.

But, this just begs the deeper question - why haven't pollsters recognized, what are too many, very obvious social shifts? It's like the woke left that can't even conceptualize how they're the new racists and how the dynamics of BLM supremacy mirrors KKK supremacy. It's the revolutionists blind-side. After most any revolution, the revolutionists become basically indistinguishable from those they overthrew.  Why?

This feels like a General Systems complexity question (see Bathalamy's research from the 1930's - 1960's).

My suspicion is that pollsters just can't control for the levels of tribal group migration/realignment we're now seeing. More importantly, they aren't trying to figure it out.  Because of this they're functionally blind with respect to the changes that actually matter for the levels of precision they're after.

Nate Silver's tunnel vision epitomizes this. They just don't feel how far the world has shifted. And, I would guess there is a sizeable systemic bias in the friends networks. They are just too isolated amongst liberal elite circles to really sense the magnitude of what is happening in the deplorable and red-pill castes.
