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.

Why Are "Cougars" Multiplying? Where Is It the Norm for Men to Have Sex With Men?

February 26, 2010, 12:57 PM

We accept the evolutionary explanation as to why older men tend to seek younger, more fertile women; but recently there has been an increase in "cougars," older women pairing with younger men. How does that trend serve our species? In his Big Think interview, Ted Fischer ponders this and other mysteries of evolution, sex, and love.

He explains that love's purpose, at least historically, has been to ensure that we bear and raise children successfully. And while that human instinct is universal across cultures, how we form family bonds differs around the world. The men of the Sambia tribe of New Guinea establish intimate relationships with one another before becoming paired with a wife. And in modern Western society, emphasis on independent sexual attraction, rather than familial influence, instigates love. Like the village matchmakers of old, however, new algorithms used by Internet dating sites attempt to calculate successful pairings.

Love, it seems, is an ever-evolving thing.
