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 Is Autism?

Autism is a developmental disorder that appears in children in their first two or three years and is characterized broadly by two components: a deficiency in social and emotional intelligence as well as a tendency towards narrow interests and repeated behaviors. But the symptoms of the disorder are far from uniform, ranging in severity and focus. "Seeing one or two cases of autism...is often insufficient to prepare a psychologist, a developmental pediatrician, or other health professional to really provide a comprehensive diagnosis," says Dr. Susan Wilczynski, director of the National Autism Center, as part of Big Think's "Breakthroughs: Autism" panel.

In fact, experts have recently renamed the disorder "autism spectrum disorder" (ASD), encompassing previously distinct conditions like Asperger's syndrome (a change that will be reflected in the forthcoming fifth version of the Diagnostic and Statistical Manual for Mental Disorders, the Bible of the psychiatric profession). Approximately 1% of American children exhibit some symptoms of an ASD.

What causes autism is still unknown, though scientists have posited vague theories. Big Think panelist Dr. Gerald Fischbach, Scientific Director of the Simons Foundation Autism Research Initiative, believes that the issue is one of connectivity among brain areas: "It’s how these regions talk to each other and how they interact that is just not quite right," he says. UCLA professor Dr. Susan Bookheimer agrees, adding that "areas of the brain that are far from each other are not as well connected, whereas areas of the brain that are very close to each other seem to be over-connected."
