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.

The Case For Having Your Groceries Delivered

What's the Latest Development?

A study recently published in the Journal of the Transportation Research Forum claims that, far from being the lazy way out of shopping, grocery home delivery has the potential to impact the environment in a positive way. University of Washington professor and study co-author Anne Goodchild and her team compared typical methods of individual shopping to basically "[putting] groceries on the bus" and found that, in Seattle at least, home delivery was far more efficient and eco-friendly. In general, and accounting for variables such as store proximity, delivery trucks emitted between 20 and 75 percent less carbon dioxide than the equivalent numbers of cars driven to the store.

What's the Big Idea?

Current home delivery services allow customers to choose when they'll receive their groceries, a benefit that doesn't coincide with efficiency. Rather, "if the delivery service can cluster people along routes...[these] can produce 90 percent less CO2 than a random route." Goodchild also notes that people who are already environmentally- and community-minded are often more willing to accept deliveries at times that are less convenient. She says, "[T]hings that are green are a little more work...Maybe here's something that takes less effort."
