What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

The Big Idea for Sunday, December 01, 2013

Old ideas don't tend to do well in cities, it is thought, because the city has an ethos that encourages interaction. The best ideas rise to the surface in this marketplace. The stagnant, old ideas, die off. 

That is why, despite the fact that technology infrastructure has made location unimportant, we’re becoming more urbanized at a more rapid rate than ever before.

Why is this? According to innovation guru John Hagel, learning faster is becoming more and more important, and we simply learn faster in cities than we could on our own.
