Friendship paradox
The friendship paradox was first observed in 1991 by sociologist Scott Lauren Feld . It describes the phenomenon that almost every person's friends have more friends than they do themselves.
Regardless of the apparently paradoxical statement, the phenomenon is real and can be explained as a consequence of general mathematical properties of graphs of social networks . However, it can also be the cause of numerous social misunderstandings.
The friendship paradox can be explained sociologically by the fact that one would rather make friends with people who have many friends than with those who have only a few friends. Or purely statistically because each individual is probably one of the friends of people with many friends.
This knowledge is one possible way of predicting the course of epidemics.
