Collective Intelligence can be measured through the actions of a group and their ability to efficiently perform a variety of tasks. More specifically through a comparison of the group's ability to perform one task which is then correlated with the same group's ability to perform a variety of other tasks.

Evidence for a Collective Intelligence Factor in the Performance of Human Groups

Scholars are interested in how collective intelligence can influence a group's performance. They are also interested in whether collective intelligence can be used to predict group performance.
