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.

Study: Bears Find Love at Highway Crossings

As human development continues to encroach on nature, there’s now a proven solution for how wildlife and highways can peacefully co-exist. Wildlife crossings are commonly used to protect the migration routes of various species. A new study published in the Proceedings of the Royal Society B presents the first evidence that they actually work, according to Discover Magazine.

Focusing on the Bow Valley area of Banff National Park in Canada, researchers spent three years studying how grizzly and black bears used the wildlife crossings. During a highway expansion project in the 1990s, crews built two overpasses and 23 underpasses to preserve the free movement of wildlife through the popular park. From over 10,000 DNA samples collected in the area, researchers determined the highway crossings were not only busy for bears, they helped them to find mates.
