Thanks for the great article, Frogza. The neurological response to cognitive dissonance does help explain the persistance of an ideology in the face of contradictory evidence.
This research would likely find the same results for any firmly held belief systems. When I see a "hard wired" neurological response such as this study implies, I look for the evoluntionary advantage that underpins it. One guess would be that small social unit cohesion in basic beliefs would make the social unit a more stable one, increasing it's chances of survival. I wonder how well that innate behavior is serving us now?
