At the democratic party blog I got bonked about for saying that Jains have the best attitude for politics. "You're right, and you're right too" attitude was a bit of a stretch for KA progressives when confronted with narrow-minded conservative/authoritarian parrots. And I can see the point, and know about the example of Germany when supremacists gained too much power.
But I still think that Jains would make the best leaders in large and diverse countries.
Have you read The Political Brain -about mental rewards for group behaviors? (I have only read articles by Weston and and curious about the book.)
