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.

What's the Latest Development?

Jan-Emmanuel De Neve, a researcher at the London School of Economics and Political Science, recently asked 2,500 Americans how satisfied they were with life. Then he analyzed their genetic makeup. What he found was that the respondents most satisfied with life were more likely to have two long versions of the gene 5-HTT which is involved with the transport of serotonin, a feelgood chemical, in the brain. "De Neve looked at the genetic makeup of 2,574 people selected to be representative of the general population, whose medical histories were recorded for the U.S. National Longitudinal Study of Adolescent Health."

What's the Big Idea?

Should depressives blame their genes? Should the irrepressibly optimistic thank theirs? Probably not. Happiness is only partly influenced by genetic makeup, but De Neve's study could provide a greater understanding of happiness and, in the future, might allow would-be parents to create a child who will be more satisfied with their life. "'This gene [5-HTT] has an important influence, but you cannot say it causes happiness. Happiness is hugely complex and your experiences throughout the course of your life will remain the dominant force on that,' De Neve said."
