The world is even smaller than you thought. Scientists reported in November 2011 that there are only 4.74 degrees of separation between any two people in the world instead of 6.
The original "six degrees" finding, (published in 1967 by psychologist Stanley Milgram,) was drawn from only 296 volunteers who were asked to send a message by postcard, through friends and then friends of friends, to a specific person in a Boston suburb.
The new research used a much bigger cohort: 721 million Facebook users, more than one-tenth of the world’s population."
Why should you care?
“People can share ideas with only a few jumps to a large portion of the world’s population and with even fewer steps to the entire population of a nation.”
We have more influence, on more people, than ever before.
For good, or evil.
