Over the past 5 years, the InfoSec community has had a miopic focus on some of the technical components of influence operations such as twitter bots. At the same time they show marginal, if any, understanding of the underlying social and media theories used in influence operations. In this talk we cover some of the basics that have worked for hundreds of years before social media existed. It focuses on the Media Effects such as two-step flow of information, gatekeeping, agenda-setting, priming, framing, spiral of silence, echo chambers, and cultivation, used to conduct those operations.
The talk itself is an introduction and highlights particular theories, and provides links for further reading. It will briefly also cover Bezmenov’s Subversion Model to provide a frame for the explanation of the social division we have been observing over the past few years, as well as support the thesis with a sociometric study showing the effects.
