There are two types of intelligence: Collected and Collective.
There is no such thing as “all by yourself” intelligence.
“Collected intelligence” is when one person or group collects intelligence primarily for its own use and benefit. It doesn’t require other people’s permission or even awareness that their data is being collected, or how it is being used.
“Collective intelligence” is intelligence collected from or contributed by many people who are aware (or have the ability to be aware) of what is being collected and how it is being used – and where those people have rights and abilities to use the intelligence for their own purposes,subject to agreed on constraints, privacy rights, etc.
Collective intelligence, according to this description, is absolutely required for reducing social fragmentation and for increasing social coherence, innovation, and prosperity for all. Collective intelligence is also required for producing anything that could be called “collective consciousness.”
Collective intelligence can also be described as “connected intelligence” which might be a good idea, since many people still use the term “collective intelligence” when they really mean “collected intelligence.”
