"When a large group of people make an 'educated
guess' -- say, about the height of Mt. Everest
"Why? Because some people guess high. Some
people guess low. But the average tends to
inexorably zero in on the correct answer. And
the more people, the more accurate they get.
"Surprised? You shouldn't be. It's the same
principle that makes free markets more efficient
than a government planner. It's why millions of
people, making individual decisions, come closest
to 'predicting' what will satisfy the marketplace."
SGA may be a good example of a "group entity" since SGA is a unique identity attribute that belongs only to the group.
"The more restrictions and prohibitions in the world,
the poorer people get." Lao Tzu (Tao Te Ching)
