Hive mind describes swarm intelligence, i.e. the intelligence of the crowd. It is derived from the social phenomenon that describes the group intelligence of many, rather unintelligent individuals (bees). In practice it means that the result of group work exceeds the sum of individual work.
Hive minds have been scientifically observed a number of times by asking several people to guess the weight of an object or animal. Whereas the individual estimates more or less missed the actual weight, the average was nearest to the actual result. Crowdsourcing makes use of this fact. Crowdsourcing compiles the knowledge of many to create a mutual information database.
