In 1929, Hungarian writer Frigyes Karinthy imagined that anyone on Earth could be connected to anyone else through a chain of six relationships at most. This was the birth of the six degrees of separation theory.

A theory turned science

In 1967, psychologist Stanley Milgram ran the experiment: volunteers were asked to send a letter to a stranger in Boston, passing it only to direct acquaintances. Result: the average chain was 5 to 6 people. The legend was born.

The digital era confirms

In 2011, Facebook and the University of Milan analyzed 721 million users: the average distance had dropped to 3.74 degrees. The world is tightening, but platforms never show us the path — they show us news feeds.

How NexusBiome applies the theory

On NexusBiome, your profile shows your distance to anyone else on the network. You see your direct friend at 1°, their network at 2°, and so on up to 6°. You can select a starting point and a target: the algorithm computes and draws the shortest path on the interactive network. Each degree has its color, each link draws itself before your eyes.

Why it matters

Understanding degrees of separation means understanding that we are all connected. A job application, an introduction, a collaboration: the path already exists — NexusBiome shows you which one to take.
