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 Do War Injuries Look Like in the Brain?

What's the Latest Development?

Researchers at NYU have recently begun an impressively large and well-funded study of 1,500 individuals who have suffered from post-traumatic stress disorder. The aim of the research, which will last five years, is to find biological markers of PTSD that could provide reliable, objective evidence of so-called invisible war injuries. "We want to elevate mental health to standard physical health," said Dr. Charles R. Marmar, chairman of the psychiatry department at NYU Langone Medical Center, and the lead investigator on the project.

What's the Big Idea?

Biomarkers are physical indications of a disease which may also suggest whether a patient is likely to contract other illnesses in the future. "Tissue damaged by a heart attack releases chemicals into the blood that can be detected. Abnormal levels of the proteins amyloid and tau, as well as shrinkage of certain areas of the brain, are considered markers of Alzheimer’s disease." The current lack of biomarkers for PTSD has been harmful because, without them, disorders can go undetected until they are disabling. Biomarkers can also be used to determine whether certain treatments are effective.
