Linkedin. British anthropologist Robin Dunbar theorized that an average person can't easily have more than 150 people in his tribe. In other words after having add 150 contacts to your Linkedin professional network we can't keep track of more. It's too complicated. Let 150 be the typical figure, if we proceed direct to the facts e.g. 500 is the number of contacts an outstanding person can produce. Is wise to think that less than 15% of networkers would have more than 500 contacts!. If we look for in the tables of Gauss distribution we obtain a standard deviation of 338 for a 85 percentile.
In summary if the average number of Linkedin contacts is 150 contacts, if more than 500 contacts belongs to a first-of- the- class networker then the probability to find someone with more than 1756 contacts is one in a million.
Conclusion: The latter entails that if number of LN networkers are 44 M, only 44 have more than 1756 connections.
Linkedin is not mathematics!
