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.

Over Time, Facebook Users Share More, But With Fewer People

March 5, 2013, 3:30 PM

What's the Latest Development?

A seven-year study of the privacy settings of about 5,000 Facebook users reveals that while the amount of personal data made available to others increased as the number of network data fields increased, the number of those others who were seeing that extra data decreased. The Carnegie Mellon University researchers say that the subjects were mostly undergraduates who signed up for Facebook in 2005 back when it was only open to college students. Over time, as Facebook offered more ways to share more information, it also refined and expanded its privacy settings, which more users took advantage of.

What's the Big Idea?

The independent study is one of the first to examine the evolution of data disclosure and online privacy over such a long period. The findings are consistent with other recent studies done over shorter periods that show Facebook users fine-tuning their privacy settings to control who sees what. Ultimately, though, the researchers concluded that with the increase in the amount of data disclosed, "so [too] have disclosures to Facebook itself, third-party apps, and (indirectly) advertisers."
