Kevin Bacon facebook 4.74 degrees game

kevin bacon facebook game Facebook's data analysis team has released what it calls the largest social networking study ever, and discovered that only 4.74 people separate strangers from each other. That's largely thanks to Facebook itself, of course, as well as other modern social networks.
Since the American social psychologist, Stanley Milgram, conducted his famous ‘small world experiment’ in the 1960s, it has been commonly accepted that most people have six degrees of separation between them.

However, a vast new study by Facebook’s data team and the University of Milan, which assessed the relationships between 721 million active users (more than 10 per cent of the global population) of the social network, has found that the average number of connections between people has dropped to four.
"When considering even the most distant Facebook user in the Siberian tundra or the Peruvian rainforest, a friend of your friend probably knows a friend of their friend," wrote the Facebook data team in a blog post explaining its research. The average number of acquaintances between any two people in the world is now pegged at 4.74. The researchers used Facebook because of the 721 million users. That huge number of users allowed for a more accurate finding. The original six degrees came from a study in the late 60′s that had people send actual postcards to specific other people via friends.

The experiment used one month and used a special algorithm to calculate the distance between any two people on Facebook using a sample path. The links between one person and another averaged 4.74 and in the US with more than half the population on Facebook, there was only 4.37 folks between each of us. "At first glance, the median friend count on Facebook — 100 — may seem surprisingly low; a quick survey of my own friends reveals that they almost all have more than 100 friends," the team wrote.

That's a sociological phenomenon that's well documented, in fact.

The information comes from research Facebook released late Monday evening on 721 million active Facebook users and their 69 billion connections, done in collaboration with Università degli Studi di Milano.
