I believe this particular study makes a point that's being missed.

Is it possible that the reason these two sides get more and more entrenched in their beliefs is that when people hear their objections treated as shit on a wall (or other words to that same effect) they tend to get defensive, and thus much less likely to accept evidence? Is it possible that this feeling of anger and frustration (even if the frustration is due to them being slower to understand a concept) makes them act more and more arrogant and rude? And could that arrogance and rudeness create similar feelings in scientists and their defenders, leading to further rudeness directed back?

Could it be that we don't just have a positive feedback loop making it more and more difficult for radiation to leave Earth (poetic license?), but another positive feedback loop making it more and more difficult for information and cooperation to flow?
