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.

Sliding Drug Scale

The British government’s chief drugs adviser has sparked controversy by claiming that ecstasy, LSD and cannabis are less harmful than cigarettes and alcohol. The claims were made by chairman of the advisory council Professor David Nutt as he attacked the government’s decision to upgrade cannabis to a class B drug. “Prof Nutt said smoking cannabis created only a ‘relatively small risk’ of psychotic illness. And he claimed advocates of moving ecstasy into class B from class A had ‘won the intellectual argument’. All drugs, including alcohol and tobacco, should be ranked by a ‘harm’ index, he said, with alcohol coming fifth behind cocaine, heroin, barbiturates, and methadone. Tobacco should rank ninth, ahead of cannabis, LSD and ecstasy,” reports The Belfast Telegraph.
