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.

Life Is Dull for the Depressed

July 19, 2010, 6:57 AM
"For people with depression the world really does look dull. That's because their ability to perceive contrast is impaired." A new experiment could help diagnose clinical depression. Participants in a study that examined clinically depressed peoples ability to discern color contrast relative to clinically healthy people were less able to discern contrast if they were clinically depressed. The experiment placed subjects in front of screens that moved from black to white and recorded the frequency of nerve responses to the color changes. Those diagnosed with clinical depression recorded fewer responses thus indicating they were less able to perceive subtle color contrasts.
