Editing Collective Intelligence (section)

Collective intelligence is understood through '''Diversity''' and '''Independence'''.

'''1. The "Average" Truth (Wisdom of Crowds)''':
Why is the "Crowd" "Smarter" than the "Expert"?
* Every "Individual" has some **"Private Information"** and some **"Private Error."**
* When you "Average" the "Many," the "Private Errors" **"Cancel Each Other Out."**
* The **"Shared Information"** (The Truth) is what "Remains."
* For this to work, the group **MUST** be **"Diverse"** and **"Independent"** (Thinking for themselves).
* "Crowds" are "Smart" only if they are "Not a Mob."

'''2. The "Echo" Chamber (Groupthink)''':
The "Failure" of the many.
* If a "Group" is "Too Similar" or "Too Close," they "Start to Copy" each other.
* The "Errors" **"Multiply"** instead of "Canceling."
* This leads to **"Bubbles"** (see Article 514) and "Poor Decisions."
* **Consensus** is "Dangerous" if it is "Forced."

'''3. The "Networked" Brain (The Internet)''':
"Global Scale" Intelligence.
* The **Internet** (see Article 159) "Allows" for "Coordination" of **Millions of People.**
* **Open Source** and **Wiki** models "Enable" "Massive Projects" that "No Single Person" could "Manage."
* We have "Created" a **"Technological Super-organism"** where "Knowledge" is "Accessible" to "Everyone" "Instantly."
* "Humanity" is "Becoming" a **"Global Brain."**

'''The 'Ox-Weight' Experiment (Galton, 1906)'''': The "Birth" of the field. Francis Galton "Calculated" the "Average" of **800 Guesses** at a county fair. The "Crowd's Average" (1,197 lbs) was **99.9% Correct** (The real weight was 1,198 lbs). It proved that "The Many" are "Greater" than the "One."
