This is the theory as I understand it. Most of the entries are guesses. Figure he’ll tell me where it’s wrong :-P.

Taking this a bit further, I suggest that Glenn’s idea of value stratification is related to an proportional overabundance of brain matter in the more abstract regions. They would have “leapfrogging loyalties” and neglect the smaller group in favor of the larger group.
“Modern liberals’ defining trait is making a public spectacle of how their loyalties leapfrog over some unworthy folks relatively close to them in favor of other people they barely know.”
The Self-Righteous Hive Mind
Given the choice between political policies that will help/harm their tribe and their clan, they will either choose to help the greater tribe at the expense of their own clan or be paralyzed by abstract perfectionism (a common behavior that arises from this trait is “letting the perfect be the enemy of the good”) and therefore ineffective in using their political influence.
