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.

Can Neuroscience Conquer Obesity?

What's the Latest Development?

The neuroscience of eating is a budding field that may have profound implications for how we understand, and ultimately defeat, the public health menace that is obesity. Regulating our food intake may require a better understanding of the brain's pleasure centers. "Pictures of mouthwatering foods can activate brain-reward pathways and stimulate the urge to eat—a response that is often countered by simultaneous suppression signals from 'executive control' centers elsewhere in the brain. In obese individuals, though, the ability to suppress the initial brain-reward signals is often impaired. Thus, biological changes in the brain’s capacity to control our drive to eat might serve to perpetuate obesity."

What's the Big Idea?

Ultimately, it remains unclear whether greater understanding will be enough to overcome the potentially harmful changes we have made to our food environment. "Our brains were designed for a time when food was scarce and starvation was a common cause of death. While too much hunger remains in modern times, most people in the United States face a challenge opposite to what our distant ancestors faced. Natural selection has not wired us for a scenario in which food is abundant, relatively inexpensive and often high in calories." Still, knowledge about how our new environment affects us may be an important first step.
