How Many People Does One Good Deed Spread To?

James Fowler and Nicholas Christakis proved what intuition suspected: kindness is contagious, and its reach extends exactly three degrees out. In their cascading generosity experiment, participants who witnessed generous behavior passed it to strangers, who passed it to strangers, who passed it again.

You're a node in this fabric whether you choose to be or not: the only question is what you're transmitting.

- Why the three-degree rule means one gesture reaches thousands

- How organ donation chains turn single donors into dozens of saved lives

- What makes a circuit breaker the hidden hero of any network
