If the James Bond movies are good for anything, they serve as a reminder that most of us in society really have no clue how the world of espionage, intelligence, and counter-intelligence really works. And while some may disagree, I don’t think there is a great need for common citizens to know the nuts and bolts of how MI6 and other intelligence agencies operate (other than to be aware of their legal and ethical bounds and their adherence to them). However, one aspect of this shadowy arm of government policy does impact citizens in the heart of our domestic society – the influence foreign governments seek to exert on elections and popular opinion in general. The targets of such activities are the thoughts of ordinary citizens, and the potential extent of this propaganda has been heavily discussed in the media in the past few years. Yet our understanding of how this malevolent influence is spread is severely lacking for such an important, potentially damaging, and well-publicized issue.
