"In Doug Engelbart's words, Collective IQ is a measure of how well people can work on important problems and opportunities collectively – how quickly and intelligently they can anticipate or respond to a situation, leveraging their collective perception, memory, insight, planning, reasoning, foresight, and experience into applicable knowledge. Collective IQ is ultimately a measure of effectiveness. It's also a measure of how effective they are at tackling the complex, urgent problem of how to raise their Collective IQ to the highest potential, so they will be that much more effective at solving complex, urgent problems. As the rate and scale of change around the world increases exponentially, so must our collective ability to dramatically increase our Collective IQ to stay ahead of the curve and thrive."
