The Magic 150

What's so special about the number 150?  Sociologists, scientists, anthropologists, military planners, and business managers all seem to agree that once the number of humans in an organizational unit exceeds approximately 150 individuals the cohesiveness of the unit begins to break down.  Why is this so?  As it turns out, there is something called "Dunbar’s number" (150), which according to Wikipedia “is a theoretical cognitive limit to the number of people with whom one can maintain stable social relationships.”  Basically, our brains are hard-wired to sustain about 150 truly meaningful relationships, beyond that number we begin to become strangers.
