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 Friday, December 21, 2012

Of all the big ideas that have risen to the top of our discourse in 2012 and will have a significant impact in 2013, there are a few ideas in particular that stand out because they have become ascendant very quickly.

The argument for gay marriage as a right, for instance, has rapidly advanced in the court of public opinion and is also likely to win in court, argues Steven Mazie. In today's lesson, Mazie shows how the leading arguments against gay marriage have unraveled in the face of a sea change in public opinion. 

"If principle and logic hold," Mazie argues, and "if the Court takes an honest look at the failure of each revision of the case against marriage equality," the new consensus in favor of same-sex marriage "will be joined by a legal recognition of the equal right of gay and lesbian Americans to marry."
