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.

Gernot Wagner: When you look at congestion, traffic congestion, you face a real issue with you getting the private benefit of hopping in your car and driving and incurring very little of the costs of the “damage” you cause for everybody else around you.  Right?  So you add one more car, congestion goes up. 

Now, you are not really incorporating that cost in your private decision.  For you personally, driving makes sense, otherwise you wouldn’t be doing it, right?  That’s sort of, again, economic principle number one.  You wouldn’t be doing it if it didn’t make sense to you.  Your benefits are greater than your personal costs.  Fine.  But there are costs to society of you driving, right?  There are pollution costs, there are congestion costs.  Right?  You driving on that bridge prevents someone else of being in that same spot as you are, and while every bridge has limited lanes and if you want to get into Manhattan there are only so many bridges to choose from and it’s kind of difficult to make the trip if there are millions and millions around you trying to make that trip during rush hour at exactly the same time.  

So, what to do?  Well it turns out, there is a system called Congestion Pricing that tries to incorporate these kinds of costs and tries to make you personally incorporate the costs of your decision to get up, get to your car and drive into Manhattan and compare the benefits, compare the costs and then look at the true dollar value of the cost of driving and say, “Well, it still makes sense to me because the benefits are more than the costs.”  Or, sometimes, of course, you would say, “Actually, it makes more sense to hop in a subway; it makes more sense to telecommute, perhaps.  It makes more sense to maybe take a bus instead of drive” because the costs now to you personally would be lower taking public transport as opposed to sitting in a car idling and causing that pollution damage, causing that congestion cost, shoving that off onto everybody else.
