The worrisome likelihood that Russians in addition to other malevolent actors are tinkering amongst world take in inwards Western Europe in addition to the USA through social media creates diverse kinds of anxiety. Are our democratic values thus delicate that a few m Facebook or Twitter memes could seat us on a dissimilar airplane virtually of import questions similar anti-Muslim bigotry, racism, intolerance, or fanaticism virtually guns? Can a butterfly inwards Minsk create a thunderstorm of racism inwards Cincinnati? Have white supremacy in addition to British ultra-nationalism gone viral?
There is an interesting analogy hither amongst the weather. The weather condition adjacent Wed is the internet lawsuit of a publish of processes in addition to variables, none of which are enormously hard to analyze. But inwards their complex interactions they create outcomes that are all simply impossible to forecast over a menstruum of to a greater extent than than iii days. And this suggests the interesting thought that peradventure world take in is itself the resultant of complex in addition to chaotic processes that plough over ascent to striking forms of non-linear alter over time.
Can nosotros practise a amend project of agreement the dynamics of world take in past times making utilisation of the tools of complexity theory? Here is a summary description of complex systems provided past times John Kingdom of the Netherlands inwards Complexity: Influenza A virus subtype H5N1 Very Short Introduction:
Complexity, in ane lawsuit an ordinary substantive describing objects amongst many interconnected parts, straightaway designates a scientific champaign amongst many branches. Influenza A virus subtype H5N1 tropical rainforest provides a prime number instance of a complex system. The rainforest contains an almost endless diverseness of species—one tin plough over notice walk a hundred paces without seeing the same species of tree twice, in addition to a unmarried tree may host over a m distinct species of insects. The interactions betwixt these species attain from extreme generalists (‘ army’ ants volition eat most anything living inwards their path) to extreme specialists (Darwin’s ‘comet orchid’, amongst a foot-long nectar tube, tin plough over notice exclusively live pollinated past times a item moth amongst a foot-long proboscis—neither would live without the other). Adaptation inwards rainforests is an ongoing, relatively rapid process, continually yielding novel interactions in addition to novel species (orchids, closely studied past times Darwin, are the world’s most rapidly evolving found form). This lush, persistent diverseness is almost paradoxical because tropical rainforests prepare on the poorest of soils—the rains speedily leach all nutrients into the nearest creek. What makes such diverseness possible? (1)Let's consider briefly how world take in mightiness jibe into the framework of complexity theory. On the positive side, world take in has some of the dynamic characteristics of systems that are oftentimes treated every bit beingness complex: non-linearity, inflection points, critical mass. Like a disease, a characteristic of world take in tin plough over notice of a abrupt "go viral" -- reproduce many times to a greater extent than rapidly than inwards previous periods. And the collective phenomenon of world take in has a characteristic of "self-causation" that finds parallels inwards other kinds of systems -- a abrupt increase inwards the currency of a sure enough mental attitude or belief tin plough over notice itself accelerate the proliferation of the belief to a greater extent than broadly.
On the negative side, the causal inputs to world take in dynamics practise non appear to live peculiarly "complex" -- word-of-mouth, traditional media, local influencers, in addition to the novel element of social media networks similar Twitter, Weibo, or Facebook. We mightiness conceptualize a given individual's take in formation every bit the internet resultant of information in addition to influence received through these dissimilar kinds of inputs, along amongst some form of internal cognitive processing. And the population's "opinions" are no to a greater extent than than the amount of the opinions of the diverse individuals.
Most fundamentally -- what are the "system" characteristics that are relevant to the dynamics of world take in inwards a modern society? How does world take in derive from a organisation of individuals in addition to communication pathways?
This isn't a peculiarly esoteric question. We tin plough over notice define world take in at the statistical aggregate of the distribution of beliefs in addition to attitudes throughout a population -- recognizing that in that place is a distribution of take in to a greater extent than or less every topic. For example, at acquaint world take in inwards the USA on the theme of President Trump is fairly negative, amongst a tape depression 35% blessing rating. And the Pew Research Center finds that U.S.A. world take in sees racism every bit an increasingly of import work (link):
Complexity theorists similar Scott Page in addition to John Kingdom of the Netherlands focus much attending on a item subset of complex systems, complex adaptive systems (CAS). These are systems inwards which the agents are themselves champaign of report to change. And significantly, world take in inwards a population of human agents is just such a system. The agents alter their opinions in addition to attitudes every bit a resultant of interaction amongst other agents through the kinds of mechanisms mentioned here. If nosotros were to model world take in every bit a "pandemonium" process, thus the possibility of precipitous non-linearities inwards a population becomes apparent. Assume a belief-transmission procedure inwards which individuals transmit beliefs to others amongst a volume proportional to their ain adherence to the belief in addition to the volume in addition to publish of other agents from whom they take away keep heard the belief, in addition to individuals adopt a belief inwards proportion to the publish in addition to volume of voices they listen that are espousing the belief. Contagion is no longer a linear human relationship (exposure to an infected private results inwards X probability of infection), simply rather a non-linear procedure inwards which the previous cycle's increase leads to amplified infection charge per unit of measurement inwards the adjacent round.

Here is a careful report of the diffusion of "fake news" past times bots on Twitter (link, link). (The graphic at the exceed is taken from this article.)
