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.

Today's Big Idea: Micro Expression

The Big Idea for Saturday, September 29, 2012

There is a national epidemic of lying, James Stewart, author of Tangled Webs: How American Society is Drowning in Lies told Big Think. Stewart was referring to public figures such as Martha Stewart, Bernie Madoff, Scooter Libby and Barry Bonds whose lies, Stewart argued, had cost society. 

And yet, psychological research tells us that we all lie constantly -- on average twice a day. Worse yet, we lie to loved ones the most. Indeed, lying is very much a condition of life. What matters is that we catch the lies that are the most harmful ones, or that society cares the most about.

Psychologist Paul Ekman has devised a tool to spot lying, based on his groundbreaking research into facial expressions, or what he calls micro expressions. It turns out that we are hard-wired to express universal emotions on our faces because there is an evolutionary advantage: when we need to make rapid decisions our body has a way of generating emotions before we have time to think them. 

So how might Ekman's tool be used effectively in the 21st century context. To catch criminals and terrorists in a lie is one area. And yet, on the other hand, what will it mean when computers become really good at recognizing the emotions expressed on our faces? That will require us to sharpen the distinction between what is a white lie and what is a bad lie.
