Every society has a certain center of gravity, around which the culture's ethics, norms, rules, and basic institutions are organized, and this center of gravity provides the basic cultural cohesion and social integration for that society. This cultural center of gravity acts like a magnet on individual development. If you are below the average level, it tends to pull you up. If you try to go above it, it tends to pull you down.
