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: Are you generally optimistic or pessimistic about the way the world is headed?

Transcript:Well I’d like to think that I’m realistic which means that the optimism is only justified if a few people take very strong action, sometimes putting themselves or their careers at risk. And then you will see this positive feedback loop where more people get inspired by this, and I mentioned some of the people that have inspired me, that have taken their family’s disease and become healthcare activists. If we have a few activists, it doesn’t have to be everybody, but everybody should join with them in doing their little part. So I think that would lead to optimism, but I’m not going to be blindly optimist. We need to have activists and people who get inspired by activists.
