mass collaboration

Mass intelligence is a process by which the mental acumen of individuals is successfully combined in some way that the noise does not drown or the signal of truth.

As the number of participants increases mass intelligence can normally only be achieved by reducing the vocabulary. The stock market is a successful case of mass intelligence (where the object is to determine asset values) which has only a two word vocabulary - "buy and "sell".

Wikis enable mass intelligence via a collaborative editing process which substantially removes the vocabulary limits, but introduces some errors common to small sample sizes.
