Bugün öğrendim ki: yaklaşık Altı derecelik ayrılık, tüm insanların ortalama olarak birbirinden altı veya daha az sosyal bağlantı olduğu fikri. Sonuç olarak, herhangi iki kişiyi en fazla altı adımda birbirine bağlamak için bir "arkadaşın arkadaşı" ifadeleri zinciri yapılabilir. 'Altı el sıkışma kuralı' olarak da bilinir.
Concept of social inter-connectedness of all people [![](//upload.wikimedia.org/wikipedia/commons/thumb/e/e1/Six_degrees_social_network.png/310px- Six_degrees_social_network.png)](/wiki/File:Six_degrees_social_network .png) A map of several branches and degrees of a small social group: Ryan is six degrees of separation from Arnold **Six degrees of separation** is the idea that all people on average are six, or fewer, social connections away from each other. As a result, a chain of "[friend of a friend](/wiki/Friend_of_a_friend "Friend of a friend")" statements can be made to connect any two people in a maximum of six steps. It is also known as the **six handshakes rule**.[ _[citation needed](/wiki/Wikipedia:Citation_needed "Wikipedia:Citation needed")_ ] The concept was originally set out in a 1929 short story by [Frigyes Karinthy](/wiki/Frigyes_Karinthy "Frigyes Karinthy"), where a group of people play a game trying to connect any person in the world to themselves by a chain of five others. It was popularized in [John Guare](/wiki/John_Guare "John Guare")'s 1990 play _[Six Degrees of Separation](/wiki/Six_Degrees_of_Separation_\(play\) "Six Degrees of Separation \(play\)" )_. The idea is sometimes generalized to the average [social distance](/wiki/Path_\(graph_theory\) "Path \(graph theory\)") being [logarithmic](/wiki/Logarithm "Logarithm") in the size of the population.
