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.

Debunking Overpopulation: Why the World Needs More People, Not Less

What's the Latest Development?

Doomsday predictions about a world with too many mouths to feed, once predicted to reach 11 billion by 2050, are being drastically reevaluated. The shift comes in light of the over 80 countries that have fewer births than required to replace the number of individuals who die each year, including every country in Western Europe, China, Japan, Russia, Poland, and Canada. "Populations forecasts now assume much lower future fertility levels, but even the present consensus that world population will be about 9.5 billion by mid-century may be too high as fertility continues to fall rapidly in poorer countries."

What's the Big Idea?

Any claims about the disadvantages of an "overpopulated" world must be weighed against the advantages of large populations, according to Nobel Laureate and University of Chicago professor Gary Becker. "These benefits include a larger number of young persons who, as mentioned earlier, are more likely to innovate, such as coming up with more efficient ways to grow food, and pay for the benefits to retired men and women. A bigger population also increases the demand for new drugs, software, social networking, and other innovations that have increasing returns to the scale of demand."
