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.

You Know the Placebo Effect. Now There's the Nocebo Effect.

What's the Latest Development?

Similar to the placebo effect, in which a fake medication can give patients the benefits of having taken the real drug, the nocebo effect is the little-studied fact that patients taking a fake drug can also experience real negative side effects. "In one remarkable case, a participant in an antidepressant drug trial was given placebo tablets—and then swallowed 26 of them in a suicide attempt. Even though the tablets were harmless, the participant's blood pressure dropped perilously low." Other data comes from drug trials where patients stop taking their placebo pills because they experience adverse side effects. 

What's the Big Idea?

The nocebo effect extends beyond fake medication to drugs that doctors prescribe patients for genuine medical problems. How doctors warn patients of side effects partially determines how those effects will be experienced. "The nocebo effect presents doctors and nurses with an ethical dilemma: on one hand, they are required to tell patients about the potential complications of a treatment; on the other hand, they want to minimize the likelihood of side effects. But if merely telling patients about side effects increases their likelihood, what is to be done?" Psychologists recommend doctors receive better training in how to communicate with patients.
