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.

Is it Safe to Use Recreational Marijuana?

What's the Latest Development?

Proponents of marijuana use have enjoyed a string of successes lately as both Washington and Colorado voted to legalize recreational use of the drug in the November 2012 election. Eight states and the District of Columbia also permit the use of marijuana for medical reasons. Despite the rising potency of the plant's active ingredient, due to a professional class of growers, and evidence suggesting that the drug slows reaction time and impairs distance perception behind the wheel, most new marijuana regulations, for medical or recreational use, fail to account for these potential risks.

What's the Big Idea?

Whether the kinds of impairment caused by marijuana use that have been documented in laboratory conditions translate into traffic accidents is still under debate. Even less sure than the drug's immediate effects, however, are its long term consequences for users' health and intelligence. "In one recent study, clinical psychologist...found that people who began using pot earlier in life and used it most frequently over the years experienced an average decline of eight IQ points by the time they turned 38. By comparison, those who never smoked pot had an average increase of one IQ point by the same age."
