While it is tempting to categorize the in-telling of a group as = to the average IQ divided by the number of members, that applies to disorganized mob or "democracy" situations, "spur of the moment."

When group members vote for truth-claims, they typically do better at making correct estimates than do the intelligentsia or "experts." This is the so-called "wisdom of the free market."

The mirroring effect of neuronal endorophins leads to a social-ist bipolarism: "highs" and "lows," as the various gestalts of human needs outpicture.

This is captured in the synthetic enculturation process of "making fads and fashions," "capturing the Zeitgeist" or tension-reduction needs of the mass or "herd."

Such man-i-pollution or manipulation is "wickedness," and noted in such items as the movie "The Matrix," "The Soulless One" by Mark Prophet, etc.
