This is beyond awesome: Pablo Gleiser, a physicist, took 12,942 issues of various Marvel comics, traced all the connections between 6,486 different characters — and produced a massive social-network map of the Marvel Universe.

Some of his findings? Superheroes have way more connections than villians — which may help explain why they win so often. “Only heroes team up,” Gleiser notes, “while villains do not.” Superheroes are superconnectors; villians sit on the periphery of the social web. This, he theorizes, is probably due to the built-in rules that comic-book authors must follow. As he writes in his paper, the PDF of which you can download here:

We believe that the origin of this division is due to the fact that, although the Marvel Universe incorporates elements from fantasy and science-fiction the arguments of the stories were restricted by a set of rules established in the Comics Authority Code of the Comics Magazine Association of America. In particular, rule number five in part A of the code for editorial matter states that “Criminals shall not be presented so as to be rendered glamorous or to occupy a position which creates the desire for emulation …”

With great power comes great responsibility. Speaking of which, Gleiser found that the single-strongest bond in the network — i.e. the tie most commonly reiterated in Marvel plots — is between Peter Parker and Mary Jane. (“A fact,” he writes, “that shows that although the [Marvel Universe] deals mainly with superheroes and villians the most popular plot is a love story.”) The next most-important superconnectors? The Thing, the Beast, Namor, and the Hulk.

That map above illustrates the sad plight of villians. It shows the strongest 300 links. The black dots are heroes — most of which are nicely and tightly interconnected. The white dots are villians, which tend to be connected only to a black dot — usually their sworn arch-enemy. (The grey dots are “other types of characters, such as people, gods or nodes with no classification.”)

But here’s a thought, fanboys. Network theory also predicts “the strength of weak ties”: I.e. the fact that while superconnectors have lots of strong connections, the most interesting, creative and unpredictable social effects come from weak links — connections between people only slightly joined. Does this hold true for the Marvel Universe? Are the stories in which those weak ties appear particularly intriguing, wacky, or unexpected than the ones that are characterized purely by strong ties? I want some grad student to tackle this one and get a PhD for it.
