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.

Fat and Cancer

March 21, 2010, 6:59 AM
Short of a causal relationship, new research shows strong correlation between fat content in the body and occurrence rates for certain types of cancer. "An increasing number of studies are finding that overweight and obese people are more likely to develop cancer of various kinds. At least half a dozen types of cancer are believed to be directly affected by weight. 'As time goes on, we're realizing that obesity is related to more cancers than we originally suspected,' said Dr. Donald Hensrud, an associate professor of preventive medicine and nutrition at the Mayo Clinic College of Medicine. Researchers are unable to prove that obesity actually causes cancer because requiring people to either gain weight or keep their weight down in clinical trials would be impossible. Most of the data come from observational studies, in which people who are thinner are probably doing many things differently than their heavier counterparts. Any number of those factors might be responsible for the difference in cancer rates."
