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.

Question: What is your economic philosophy?

Paul Krugman: I’m a liberal, and in the proper sense of it. I believe in we are our brothers’ keepers. Not in the sense of communism, but a wealthy, civilized country has an obligation to take care of its less fortunate, and to provide a safety net for everybody.

I believe in democracy in the broad sense, that we should have a shared political vision.

There was a time when I was very young when I flirted with conservatism. I think it’s a phase that people go through. You could see there were excesses; but it didn’t last very long.

And the only thing I would say is I don’t know that my politics have changed much, but I have become more political.

When I was in my 20s, maybe even when I was in my 30s, I could imagine that policy was really a matter of intelligent discussions between people and the best ideas would automatically prevail. And well, that’s not the way it is. There are discussions among intelligent people; but you have to do more than just; being right is nowhere near enough.
