Study shows people have an upper limit on the number of friends they can add to their social network

(Phys.org)—A pair of researchers has found when people add someone new to their "friends" list, each is more distant than those in the inner circle. In their paper published in the Journal of the Royal Society Interface, Michael Harré and Mikhail Prokopenko, both with The University of Sydney in Australia, describe test data they analyzed covering both hunter-gatherer societies and people living in modern conditions, what they found and what it might mean for people moving forward using virtual social networks.
