What is the “six degrees of separation” theory? What does it say about how we’re connected? What is a 6 degrees of separation example?
The six degrees of separation theory is the idea that every person in the world is connected to every other person in the world by a chain of family members, friends, or acquaintances that number no more than 5 people. The idea was popularized by the game “Six Degrees of Kevin Bacon.”
We’ll cover the origins of the “six degrees of separation” theory, look at a 6-degrees-of-separation example, and see how the theory is connected to Malcolm Gladwell’s idea of “connectors.”
The “Six Degrees of Separation” Theory
How do you spark a trend that spreads like wildfire, or turn a product into the latest must-have item? You create a social epidemic. Social epidemics are aided by the “six degrees of separation” theory. The Tipping Point explains how social epidemics — spreading ideas, messages, behaviors, and products — function like viruses, growing gradually until they reach a critical mass (the tipping point) and explode.
6 Degrees of Separation
The “six degrees of separation” theory starts with Stanley Milgram. In the 1960s, psychologist Stanley Milgram conducted the “small-world experiment” to research how closely people are connected. He sent letters to 160 people in Nebraska, giving them the name and address of a stockbroker in Boston and instructing them to write their name on the letter and then send it to a friend or acquaintance who might get the letter one step closer to that stockbroker. Each person who received the chain letter would do the same, until a friend or acquaintance of the stockbroker finally received it and would send it directly to him.
Six degrees of separation meaning: At the end of the experiment, Milgram found that most of the letters reached the stockbroker in five or six steps, creating the concept that people all over the world are all connected by six degrees of separation.
Even further, Milgram discovered that half of the letters were ultimately delivered to the stockbroker by three people. Although everyone is linked by just six degrees of separation, a small group of people are connected to a disproportionately large number of people. Those few, well-connected people are the Connectors.
Connectors: People With Strong Social Networks
Connectors are people who seem to know everyone. You can find Connectors in every walk of life. Connectors are sociable, gregarious, and are naturally skilled at making — and keeping in contact with — friends and acquaintances. To understand the special power of connectors, we need to understand the “six degrees of separation” theory and the profound connectedness of us all.
Connectors tend to be connected to many communities — whether through interests and hobbies, jobs that cause them to work with people in other fields, or other experiences. Their strength is in occupying many different worlds, and bringing them together. Connectors have fewer than six degrees of separation. They may have 2 or 3 degrees of separation.
However, Connectors are not close with all their connections. In fact, Connectors’ power is in having lots of acquaintances, or “weak ties.” Your acquaintances typically have different social circles and communities — exposing them to different people and information — than you, whereas your friends’ knowledge and social ties tend to largely overlap with your own. Thus, your friends can help spread a message in the same communities you occupy, but weak ties can help spread that message beyond your reach because they belong to different worlds than you do.
