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.

This Text Message Will Self-Destruct In 90 Seconds

December 4, 2012, 1:22 PM

What's the Latest Development?

Representing one potentially big leap for online privacy advocates everywhere is Wickr, a free messaging app that allows users to determine how long the message -- text, image, audio, or video -- exists in online space. The lifespan of the message can last from one second to six days, and the countdown begins as soon as the receiver opens it. Once the timer reaches zero, all traces of the message disappear. Co-founder Nico Sell says she and her team were inspired by self-destructing communications like those in the TV show Mission: Impossible.

What's the Big Idea?

It's common knowledge -- or should be -- that everything an individual does online is stored somewhere, potentially forever, by one or more third parties. Law professor Fred Cate says that there aren't many privacy protections when it comes to sharing data online, and individuals can't do much about it. However, he says, "There has been a lot of discussion in recent years about this idea that you ought to be able to sort of overcome your past...We've all sent intemperate emails we wish would have disappeared." The Wickr team hopes to eventually use its code's destructive powers on e-mails, phone calls, and Facebook posts.
