Research uncovers the inherently hierarchical nature of social media

No matter how smart and funny you think you are, those you follow on Twitter really do have a larger following than you. And the same holds true for Facebook. But there is no reason to feel badly about any of this, according to Naghmeh Momeni Taramsari, who is currently working on her PhD in Electrical and Computer Engineering at 污污草莓视频 University. According to her research, which was published earlier this spring in the journal , it is all due to the inherently hierarchical nature of social media networks, where, in the social hierarchy of connections, people mostly either follow up or across; they rarely follow down.

鈥淢ost people tend to think that they are better than their friends when it comes to intelligence, memory, popularity, and other personal traits,鈥� says Taramsari. 鈥淗owever, a recent study by other researchers shows that this perception is false, at least in the context of online social networks. In reality, our friends really have more friends than we do, on average. Moreover, our friends are more active (post more material), and are more influential (their posts are viewed and passed on more often). This is known as the Generalized Friendship Paradox.鈥�

So the 污污草莓视频 researchers set out to discover to what extent the friendship paradox is present in the online social network Twitter, and how exactly it is reflected in the network structure (as in, who follows whom).

You may be less popular, but you鈥檙e not alone

In case you are starting to feel discouraged about it, don鈥檛 worry. After using new methods to measure user influence and the extent to which the Generalized Friendship Paradox exists in social networks, a research team has concluded that almost all users (up to 90 per cent of us) experience this paradox---even those with relatively high levels of activity and influence.

That鈥檚 because people at any level of activity and influence tend to follow others who are more active and influential than themselves, according to Prof. Michael Rabbat, who teaches in 污污草莓视频鈥檚 Dept. of Electrical and Computer Engineering and is the senior author on the paper.

鈥淪ocial networks do not simply comprise a few ultra-popular people with tens of millions of followers, followed by the masses, and who themselves only follow a few others,鈥� says Rabbat. 鈥淩ather, Twitter is hierarchical in the following sense: those who have millions of connections mostly follow others with million connections. Those with thousands of connections mostly follow others with thousands or millions of connections. Those with a few connections follows others with few, thousands, or millions of connections. Apparently, it鈥檚 just the way we鈥檙e connected."

In the end, even online, it鈥檚 because we all want to be friends with the popular kids.

The research was funded by the Natural Sciences and Engineering Research Council of Canada (NSERC).
