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.

That Gym Class Isn't Making Your Kid More Active

What's the Latest Development?

A review published last week in the journal BMJ examined 30 studies, published over more than 20 years, that dealt with exercise interventions for children. In many cases, expectations that the interventions would encourage kids to be more active overall didn't bear out. "In general, well-designed, well-implemented and obviously very well-meaning physical activity interventions, including ones lasting for up to 90 minutes, added at best about four minutes of additional walking or running to most youngsters’ overall daily physical activity levels."

What's the Big Idea?

Lead reviewer Brad Metcalf says that a couple of factors may be at work, including the possibility that kids, feeling as though they've put in their "time," activity-wise, are deciding to spend the rest of the day being "extra-sedentary." That said, he and his team do not believe that schools should give up on exercise programs. Physiology professor Frank Booth, who was not involved with the review, suggests researchers go back to the source: "Kids naturally love to run around and play...[b]ut they’re just not doing it as much now. And we don’t know why."
