Emotional manipulation is such a strangely intimate place to discover you’re the subject of surveiilance-cum-manipulation, that even your unguarded moments of sharing feelings are subject to someone trying to get something out of you. We want to call into account what makes this system of control possible, but if Cornell is any example of what to expect from the fallout, no one is going to be held accountable for companies like Facebook recklessly endangering users – yet again. For those of us observing this spectacle in a sort-of state of self-aware, displaced horror reserved for those moments when life and sci-fi dystopia cross shadows, it has never been more clear that Facebook’s ideas about organizing society are wholly broken.

In a “tipping” model, each node in a social network, representing an individual, adopts a property or behavior if a certain number of his incoming neighbors currently exhibit the same. In viral marketing, a key problem is to select an initial “seed” set from the network such that the entire network adopts any behavior given to the seed. Here we introduce a method for quickly finding seed sets that scales to very large networks. Our approach finds a set of nodes that guarantees spreading to the entire network under the tipping model. After experimentally evaluating 31 real-world networks, we found that our approach often finds seed sets that are several orders of magnitude smaller than the population size and outperform nodal centrality measures in most cases.
