  • Happiness is contagious.
  • Your future spouse is likely to be your friend’s friend.
  • Your friends’ friends’ friends can make you fat – or thin.

These are just a few of the startling findings of internationally renowned scientists Nicholas A. Christakis and James H. Fowler. In Connected, they present intriguing new evidence that our real-life social networks shape virtually every aspect of our lives. How we feel, whom we marry, whether we fall ill, how much money we make, and whether we vote – everything hinges on what others around us are doing, thinking, and feeling.

Connected shows that our world is governed by the Three Degrees of Influence Rule: we influence and are influenced by people up to three degrees removed from us, most of whom we do not even know. For example, your friend’s friend’s friend has more impact on your happiness than $5,000 in your pocket. Our social networks underlie financial scams, eating disorders, substance abuse, and suicide clusters, but also voter turnout, innovation, altruism, and “random” acts of kindness.

Provocative, insightful, and useful, Connected explains why emotions are contagious, how health behavior spreads, why the rich get richer, and much more. Overturning the notion of the primacy of the individual, Connected provides a revolutionary new paradigm – that, like schools of fish changing direction in unison, we are unconsciously led by the people around us. Connected will forever change the way we look at one another – and ourselves.
