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.

What's the Latest Development?

Amid the reflection provoked by the human population milestone of seven billion, Deutsche Bank’s Global Strategist Sanjeev Sanyal says the future will not be one of too much population growth, but too little. U.N. forecasts that world population will rise to 9.3 billion in 2050 and surpass 10 billion by the end of this century misrepresent underlying demographic dynamics, he warns.

What's the Big Idea?

In fact, it is likely that world population will peak at nine billion in the 2050’s, a half-century sooner than generally anticipated, followed by a sharp decline. "One could argue that this is a good thing, in view of the planet’s limited carrying capacity. But, when demographic dynamics turn, the world will have to confront a different set of problems." Fertility rates are plunging in most countries, one of the shifts with big implications for global labor supply.
