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.

Since the end of the Cold War, popular anxiety over the nuclear threat has largely shifted to a fear of terrorism. But prospects of global atomic annihilation did not, sadly, end in the 1980s.  Let's start with a few facts and figures. Total nuclear warheads in the world: ~10,000 Total ...

As the robins begin to sing, the tulips bloom and the dreadful winter recedes from memory, the surest sign of spring pops into the headlines: Paul Ryan's draconian budget bill.

Like two million other viewers, I am a fan of “The Daily Show with Jon Stewart,” and I think faux-reporter Samatha Bee is pretty funny. I laughed out loud a few times last night when I saw a re-broadcast of a show in which Ms. Bee investigated a report that the federal government spent $172 million ...

“A spectre is haunting Europe,” Marx wrote semi-ironically in 1848, “the spectre of communism.” Almost 170 years after the publication of the Communist Manifesto, the apparition of class warfare is making some wealthy people bug out in outlandishly ridiculous ways. The most alarming and ...

A major new research study shows that income mobility in the United States is right about where it was forty years ago. That may sound like good news if you were assuming that the American Dream has been in decline over the generations, but don't stand up and cheer just yet. First, mobility wasn ...
