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.

Dennis Charney: One of the things that we have found in our research is that in general we don't make full use of the capacity of the human brain.  We identified that actually initially from hearing from a couple of the POWs when they were in solitary confinement.  They told us that when they were in solitary confinement for years and all they had was the ability to think that they developed unusual cognitive capacities that they never had before when they were in solitary confinement, like they were essentially exercising their brain.

One individual told us he was able to multiply eventually many numbers by many numbers, 12 numbers by 12 numbers accurately.  Never was able to do that before.  Another told us that he was able to remember to very early times in his childhood, like remembering the names of the students in his kindergarten class.  Admiral Shoemaker, one of the individuals that we came to admire a lot, built a house in his mind nail by nail, cabinet by cabinet, room by room and then when he got out he built that house, and when we met him he was having a fight with his wife because she wanted to renovate the house and he said no way was that going to happen.

That brought home that when you exercise your brain and you don't have any outside distractions because you're in solitary, you have enormous capacities.  Our research group subsequently hearing about this and others around the country have now taken a tact that through specific exercises we might be able to enhance brain plasticity, or using more of the capacity of the human brain.  

For example, we now have a research study in which where through exercises, through psychological exercises are trying to retrain the circuits that are involved in depression.  It's not a typical psychotherapy.  It's very specifically oriented toward improving the circuits that are involved in causing human depression.  So far there are some positive results around that.  For certain forms of learning and memory problems, new therapies have been developed that exercise the human brain around learning and memory mechanisms.  With human anxiety, practicing certain techniques that tap into the circuits and the chemistry of anxiety is now an area of focus.  Mindfulness therapy is an example of that.  

So that's a really emerging area to develop new therapies, non pharmacological therapies, that exercise the human brain to improve learning and memory problems and anxiety and problems with depression.
