Pragma Synesi – interesting bits

Compendium of interesting bits I come across, with an occasional IMHO

Social circle limit 150?

 http://www.dailyreckoning.us/blog/?p=517

“One of the most fascinating tidbits from the new Bill Bonner book, Mobs,
Messiahs, and Markets http://www.agorafinancialpublications.com/Mobs.html,
is the discovery by anthropologists of a limit to the number of human
interactions the brain is capable of processing.  Citing British
researcher Robin Dunbar:

‘The figure of 150 seems to represent the maximum number of individuals
with whom we can have a genuinely social relationship that goes with
knowing who they are and how they relate to us.  Putting it another way,
it’s the number of people you would not feel embarrassed about joining
uninvited for a drink if you happened to bump into them in a bar.’

“What’s more, Dunbar’s research uncovered dozens of examples of
hunter-gatherer cultures whose average village size was 150.  So it goes
for the modern-day Hutterite communities of the Dakotas and the Canadian
Prairies.  A cohesive fighting unit in the military is limited to about
150 or 200.  But as Bonner and co-author Lila Rajiva point out, this
number is far smaller than what we find in most modern organizations.”
