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.

Which of Your Genes Makes You Truly Unique?

What's the Latest Development?

Ironically, what are called compatibility genes give each person their individuality, according to a new book by immunologist Daniel Davis called The Compatibility Gene. "From early on in the evolution of life, individual cells – and later multicellular organisms – developed the ability to recognise that which was the same as them, and that which was different. Davis recounts how, when we are growing as fetuses, our compatibility genes train the immune system to recognise our own cells and tissues as 'self' and so, in healthy people, they know what not to attack."

What's the Big Idea?

The more diverse our gene pool becomes, the first major instance of which occurred as humans left Africa to settle in Europe, the more strongly defined our compatibility gene becomes. For this reason, while millions of people may be willing organ donors, finding a transplant that would not be rejected by the body of the person in need is an extremely difficult task. Because different compatibility genes cause different responses to vaccinations, different disease susceptibility, and different responses to treatment, recognising compatibility genes will ultimately give better health for all.
